Outer Rim Territories / Legends The Outer Rim Territories , simply known as the Outer Rim and alternatively called the Outer Rim Systems , were located outside the Mid Rim . The Outer Rim was the least widely settled and explored expanse of the galaxy before Wild Space and the Unknown Regions . The largest region in the galaxy , it was strewn with diverse worlds , and rugged , primitive frontier planets . History . Pre - Republic era . For much of galactic history , little was known about the history and cultures of the Outer Rim until the formation of the Galactic Republic in 25 , 053 BBY . During this period , the Gree Enclave reached its apex while the reptilian Kwa developed the Infinity Gate s which allowed them to teleport between worlds . Between 30 , 000 to 25 , 200 BBY , the far - reaching Rakata n Infinite Empire ruled a number of Outer Rim worlds including Tatooine , Dantooine and Honoghr . By the dawn of the Republic , these civilizations had faded into history and little remained of their former power . Around that period , the worlds of the Tion Cluster were colonized by Human settlers from an ancient Core Worlds sleeper ship . Between 25 , 130 to 25 , 100 BBY , the tyrannical Tionese dictator Xim the Despot conquered much of the Tion Cluster including the Livien League . Eventually , his empire stretched from the Radama Void to the Maw . However , his incursions into the Si ' Klaata Cluster brought him into conflict with the growing Hutt Empire . During the Third Battle of Vontor in 25 , 100 BBY , Xim was finally defeated by Kossak the Hutt ' s newly acquired army of Klatooinian , Vodran , and Nikto mercenaries . Xim died a slave in the dungeons of Kossak on Varl , but Tionese history claimed that he was treacherously killed at Vontor . The Tion Cluster split into several competing states including the Honorable Union of Desevro & Tion . The Old Republic era . Circa 25 , 000 BBY , the discovery of the Perlemian Trade Route linked the growing Republic with the Outer Rim world of Ossus , which became the domain of the Jedi Order over the subsequent millennia . Eventually , the Republic began colonizing hundreds of other worlds within the area of Ossus . While the Republic continued to expand in the Core Worlds and the Colonies , Ossus became a fortress world blocking Tionese and Hutt expansion into the Perlemian . In 24 , 000 BBY , war broke out between the Republic and the Union , spreading to both sides of the Perlemian . The Republic won by turning the Hutts against the Tionese , ending the Union ' s existence as an independent state and paving the way for galactic domination by the Core - based Republic . By 23 , 900 BBY , the worlds of the former Honorable Union had all joined the Republic as a means of protection against the Hutts with the exception of Desevro which remained proudly isolationist . In 12 , 000 BBY , the Republic came under the influence of the theocratic and humanocentric Pius Dea sect which posited Contispex I as Supreme Chancellor . Taking advantage of the unpopularity of the Hutts among the Republic ' s citizens , Constipex sanctioned a crusade against the Hutts . Over the following centuries , his descendants sanctioned several crusades against some rival alien sects in the Outer Rim which fought back , leaving the galaxy in a never - ending state of alternating hot and cold wars . Though Pius Dea rule came to an end in 11 , 000 BBY , the repercussions of these crusades would sour relations between the Core and the Outer Rim over the millennia . Around 10 , 000 BBY , Vall Kumauri established the short - lived Kumauri Empire in the remote frontier areas of the Outer Rim . At its height , the Kumauri Empire included more than thirty star systems . Eventually , the Republic gained the upper hand in the conflict and re - conquered all the territory he had seized . Kumauri ' s legacy would live on in the tradition of warship design that culminated in the " Cal " - class battleship . At the end of the Hundred - Year Darkness in 6900 BBY , several Dark Jedi were defeated at Corbos and banished into the uncharted expanses of the Outer Rim . The Jedi exiles fled to the remote world of Korriban . After conquering it , they interbred with the native Sith species through the art of Sith alchemy and began a long period of building and expansion . The Sith Empire developed in complete isolation in the Outer Rim for two thousand years before it eventually rediscovered the Republic . Under the Sith Lord Naga Sadow , the Empire invaded Republic space in 5000 BBY , during the Great Hyperspace War , but it was defeated . The Sith Empire was believed to have been destroyed by Republic forces during the Second battle of Korriban , but in fact survived due to a single Sith Lord who escaped to the Unknown Regions . There , this new Sith Emperor , whose rule lasted for well over a thousand years , rebuilt the Sith Empire in preparation for a Great Galactic War against the Republic . With the Sith threat apparently vanquished , the Republic continued exploring and colonizing worlds in the Outer Rim . In 4800 BBY , the spice ryll was discovered on the Outer Rim world of Ryloth , home of the humanoid Twi ' lek species . However , the Neimoidians seized exclusive distribution rights to the spice and sold them to the newly discovered Porporite species . Unfortunately , the spice drove them into a homicidal frenzy . Terrified , the Neimoidians hired several Gank mercenaries to protect them . Instead , the Ganks exterminated the Porporites and then embarked on a full - scale war against the Republic , but were eventually put down by the Jedi . Around 4000 BBY , the Mon Calamari and Quarren species of watery Dac were discovered though its inhabitants had already been exploring nearby star systems for several years . During the Old Republic era , the Outer Rim had several remote , scarcely populated planets that included expensive resort worlds for rich tourists , ruined settlements and , it was rumored , hideouts for the Black Sun , the Hutts and several outlaws . The Outer Rim Oreworks corporation used its exploratory branch to search useful planets that the corporation could settle and exploit . The Old Sith Wars era . During the Great Sith War in 3996 BBY , the Krath under Aleema Keto destroyed the Republic jump station of Kemplex IX in the Auril sector . Shortly afterward , the Krath and their Jedi pursuers were destroyed in a massive supernova which engulfed the Cron Cluster , a nearby stellar body of ten densely packed stars . The ensuing blast devastated the surface of the ancient Jedi outpost of Ossus and created the Cron Drift . During the Mandalorian Wars ( 3976 - 3960 BBY ) , the Mandalorians chose the Outer Rim to begin their campaign against the Galactic Republic . In 3976 BBY , the Mandalorian Neo - Crusaders under Mandalore the Ultimate embarked on a campaign of conquest along the Outer Rim Territories , on the edge of Republic space . Conquering worlds as varied as Althir III and Cathar , the Neo - Crusaders had carved out a clan territory larger that the space ruled by the Hutts in less than a decade . Weakened by the Sith War , the Republic and the Jedi Council refused to intervene at first . In 3970 BBY , the Myrialites under Provisional Governor Myrial of Argazda seceded the Kanz sector from the Republic . Myrialite forces invaded worlds in that sector that resisted her rule including Lorrd and Amaltanna . For three hundred years , her successors ruled the sector as an independent fiefdom known as the Argazdan Redoubt — enslaving many peoples including the Lorrdians . In 3670 BBY , the " Kanz Disorders " came to an end when Jedi / Republic forces under the Lorrdian Jedi Master Mari - Elan Nora toppled the regime and restored Republic rule to the sector . In 3963 BBY , the Mandalorians invaded the Galactic Republic proper , forcing the Republic to enter the war . In defiance of the Jedi Council , the Jedi Knights Revan and Malak led the Republic Navy in a fierce counter - offensive against the Neo - Crusaders , winning key battles at Taris , Jaga ' s Cluster and Althir . During the cataclysmic battle of Malachor V , much of the Mandalorian fleet was destroyed and the planet was fractured to the core . Defeated , the Mandalorians capitulated and destroyed their weapons and armor . In 3960 BBY , during the Jedi Civil War , Telos IV was devastated by a Sith fleet under the command of the renegade Jedi - turned - Sith Lord Malak and former Republic Admiral Saul Karath . Later , in 3956 BBY , Sith forces leveled the surface of Taris , destroying the world - spanning city and killing billions . By 3950 BBY , much of the Rim had fallen into chaos as a result of infighting amongst the various surviving Sith warlords . Thus , the Republic was able to reclaim much of the Rim that had been under Sith control since the Great Sith War . In 3700 BBY , the female pioneer Freia Kallea discovered a new hyperspace route which became known as the Hydian Way . Spanning the width of the galaxy , the Hydian Way ran from the Outer Rim world of Bonadan and continued through the Core Worlds to Eriadu on the other side . The Hydian helped open up much of the galaxy beyond the region known as the Slice , fundamentally altering the scale of galactic civilization . As a result , the Republic established new colonies in the Mid Rim and Outer Rim Territories . In 3681 BBY , the resurgent Sith Empire struck back against the Republic in the Great Galactic War . Catching the Republic by surprise , the Sith seized many worlds in the Outer Rim Territories , destroyed the shipyards at Sluis Van and cut off the Rimma Trade Route . The Republic suffered further defeats at Agamar and Utapau , and was constantly harassed over the century . By 3653 BBY , the Republic had been driven back to the Core Worlds , leaving the Sith in control of much of the Rim . Following the Sacking of Coruscant , the Republic was forced to give up many outlying systems to the Sith in the punitive Treaty of Coruscant . The end of the Great War set the stage for a Cold War between the Sith Empire and the Republic in the years that followed . This cold war saw a number of border skirmishes and proxy wars , pushing the two superpowers to the brink of another war . During this time , Mandalorian armor and weaponry was mysteriously seen in the hands of Outer Rim pirates . Eventually , someone was assigned to discover the source of the materials . The New Sith Wars era . In 2000 BBY , the Republic once more faced the menace of the Sith in the New Sith . Over the centuries , the Republic continuously fought various Sith factions across the galaxy including the Rim . The losses for the Republic were so catastrophic that a dark age began in 1100 BBY , with widespread social unrest and economic collapse . The collapse of the HoloNet and interstellar commerce precipitated a breakdown in communication and trade between the Core and the Rim . The Republic itself shrank to a mere rump state surrounding the Core Worlds , with the Sith Empire encompassing virtually the rest of the entire galaxy . The Jedi took over absolute authority , ruling the remainder of the Republic directly . In 1000 BBY , the Sith were finally defeated at Ruusan in the Mid Rim although much of the galaxy was left scarred and devastated by the attrition warfare . Tensions still lingered between inhabitants of the Outer Rim and the Core Worlds due to the former ' s perceived exploitation by the latter , as in the case of Apatros which was controlled by the Outer Rim Oreworks company . Both the Republic and the Sith sought to exploit the labor and resources of many Rimward worlds . Taking advantage of regional tensions , the Sith enticed many Rim inhabitants into their military forces and the Sith order . Rise of the Empire era . Under the Ruusan Reformation instituted by Supreme Chancellor Tarsus Valorum in 1000 BBY , many Outer Rim systems and sectors benefited from the Republic granting greater administrative power to local and sector governments . With the demobilization of the Republic Military in favor of smaller Judicial Forces , many Outer Rim governments , such as that of Utapau , developed their own local defense forces . Over the centuries , much of the galaxy including the Outer Rim presumably recovered from the Sith Wars . Still , the region was considered remote and undeveloped by the Core - based government . Around 702 BBY , the Grissmath Dynasty ruled the Meridian sector . The dynasty exiled dissidents to Nam Chorios and attempted to exterminate prisoners by seeding the planet with the Death Seed plague . However , they survived and their descendants would become known as Oldtimer s . At an unknown date , the capital Meridian was reduced to a charred radioactive ball as a result of orbital bombardment . Soon , the Grissmath Dynasty collapsed . In 600 BBY , a fallen Jedi Knight named Allya was exiled to the rugged frontier world of Dathomir . The planet had served as an outlying penal colony since it was colonized around 3000 BBY by the Paecian Empire . Gradually , she established a matriarchal Force - sensitive cult known as the Witches of Dathomir . In 490 BBY , a free - enterprise fiefdom known as the Corporate Sector was established in the Outer Rim , in the Tingel Arm region , to resolve differences between the Republic government and the various corporations and to establish a free trade zone . Over the following centuries , the sector became dominated entirely by various corporate interests including Kuat Drive Yards , Cybot Galactica . The sector had its own government which remained outside the jurisdiction of the Coruscant government known as the Corporate Sector Authority . In 340 BBY , the Jedi training vessel " Chu ' unthor " crashed on Dathomir . A group of Jedi ( including Yoda , Gra ' aton , and Vulatan ) were sent to attempt a rescue of the vessel ' s crew and passengers , but were stopped by the Witches of Dathomir . However , after Yoda saved the life of a young witch named Rell , the two parties were able to come to a peaceful settlement . In 300 BBY , the Republic took over Lianna in the Tion Cluster from Barseg . In 150 BBY , the Bakur Mining Corporation of Hemei IV under Captain Deredith Arden colonized the planet of Bakura in the Shiritoku Spur . Around 100 BBY , Sienar Technologies set up operations on Lianna . Soon after , the company was taken over by Kerred Santhe , who moved his company ' s headquarters to Lianna . In 124 BBY , the Jedi Master Omo Bouri helped pass the Treaty of Trammis . However , that same year , the Galactic Senate declared the Outer Rim to be a free trade zone . This allowed corporations like the Trade Federation and the Commerce Guild to represent local governments that aligned with them in the Senate , giving them voting power . In 53 BBY , the dictatorial Governor of Telos Crion was overthrown during the Telosian Civil War . In 44 BBY , the pirate Iaco Stark was defeated in five consecutive battles around Troiken during the short - lived Stark Hyperspace War . Despite the defeat of the piratical Stark Commercial Combine , the heavy casualties sustained by the Republic forces in bringing down the insurrection renewed calls for the rejuvenation of the Republic Army and Navy . In 33 BBY , a trade summit on Eriadu was interrupted by the successful assassination of six Trade Federation Directorate members and a failed attempt against Chancellor Finis Valorum . The Summit ended prematurely , with nothing resolved . The Senate unilaterally passed Senate Resolution BR - 0371 which increased taxation of hyperspace routes in the Mid and Outer Rim with revenue going to the Republic . Aspiring Senator Palpatine — who had orchestrated the assassination as Darth Sidious — was a prominent supporter of the resolution . In defiance of the taxation of the Outer Rim trade routes , Trade Federation Viceroy Nute Gunray blockaded the Mid Rim world of Naboo in 32 BBY . Concurrent with the events on Naboo , the Force - strong Anakin Skywalker was discovered by Jedi Master Qui - Gon Jinn on the remote desert world of Tatooine . Shortly afterward , Qui - Gon and his Padawan Kenobi were attacked by Darth Maul . In 29 BBY , the Republic Outland Regions Security Force under Wilhuff Tarkin launched an unsuccessful attack against the planet Zonama Sekot in the Gardaji Rift . In response , the sentient world unveiled its own hyperdrive system and fled into the Unknown Regions . Clone Wars . Between 24 BBY to 22 BBY , dissatisfaction with the Republic for various reasons culminated in the Separatist Crisis . The Outer Rim , dissatisfied with their lack of representation in the Senate , and the disproportionate amount of economic or military attention they received , even during crises , made up a large portion of those who supported the Separatists . Under the leadership of former Jedi Count Dooku , various worlds , corporations and factions across the galaxy seceded from the Republic . Many Outer Rim worlds including Geonosis , Muunilinst , Jabiim and Sullust joined the budding Confederacy of Independent Systems , offering their labor and resources to the Separatist cause . In 22 BBY , the Elrood , Danjar , Tantra , Sluis , Lahara and Abrion sectors left the Republic ; bringing parts of the Rimma Trade Route , Mirgoshir hyperspace crossroads and over 200 agriworlds under Separatist control . Later that year , the Clone Wars started with the First Battle of Geonosis which pitted the clone - based Grand Army of the Republic against the Separatist Droid Army . Lianna was strategically important to the Republic as the site of a Sienar Fleet Systems starfighter facility . With Raith Sienar ’ s designers working on new fighters for the Republic Navy , it was invaded by Separatist forces . However , Republic forces under the Jedi General Cei Vookto repelled them . In 22 BBY , Republic forces under Kenobi and Skywalker captured the Separatist financial center Muunilinst . Another important Outer Rim planet was Tatooine since Jabba the Hutt controlled major routes . Obi - Wan Kenobi , Anakin Skywalker and Ahsoka Tano went there to arrange a peace treaty with Jabba as did Count Dooku . This resulted in the Republic earning the alliance of Jabba Desilijic Tiure ' s criminal empire against the CIS during the war . During the Battle of Hypori , the cyborg Kaleesh General Grievous made his debut . That same year , the Republic suffered a massive defeat at Jabiim . In 20 BBY , Honoghr was devastated by the toxin Trihexalophine1138 released from the crashed " Lucrehulk " - class Core Ship " Gahenna " . Separatist forces also conquered Gentes , enslaving the native Ugnaughts . Republic forces under Skywalker succeeded in securing the key HoloNet hub of Praesitlyn . By 19 BBY , the Republic had driven much of the Confederacy from the Core Worlds and Colonies into the Mid and Outer Rims . This set the stage for the Outer Rim Sieges , which embroiled worlds as myriad as Saleucami , Utapau , Sluis Van and Felucia . With the death of the Separatist Council on Mustafar , the Confederacy was defeated by the Republic ' s successor state — the Galactic Empire . The Imperial Period . Much of the early Imperial Period was spent suppressing the remaining Separatist holdouts including Acherin , New Plympto and Enarc . In retaliation for the signing of the Petition of 2000 by both Mon Calamari and Quarren senators , their homeworld of Dac was invaded by Imperial forces under Grand Moff Wilhuff Tarkin . Under Order 66 , all Jedi operating in the Rim were targeted for execution , forcing the survivors into hiding . In large part because of the Imperialization efforts shortly after the formation of the Empire , the Outer Rim Territories were occasionally referred to as the Imperial Outlands . In addition , the Outer Rim was also subject to several campaigns in the Reconquest of the Rim . Due to its distance from the Core Worlds , and its former status as the core of Confederacy of Independent Systems support , the region was home to many supporters of the Rebel Alliance . Jedi Knight Luke Skywalker — son of Anakin Skywalker — was raised on the desert world of Tatooine . Mon Calamari Admiral Gial Ackbar , who became a prominent naval commander in the Alliance and New Republic during the Galactic Civil War , was a native of the watery world of Dac . Jedi Master and Alliance operative Kyle Katarn , who destroyed the dark trooper program , came from the moon Sulon in the Sullust system . Grand Moff Tarkin was assigned the difficult task of bringing and keeping the Outer Rim Territories in line . Much of the Outer Rim was consolidated under Oversector Outer , patrolled by the Outer Rim Imperial Fleet . As part of the Tarkin Doctrine , the planet - destroying Death Star superweapon was constructed for twenty years over the planet Despayre through the use of slave labor . Soon after the battlestation was completed in 0 BBY , Despayre itself was destroyed to test the Death Star ' s effectiveness . As a means of increasing the Empire ' s presence in this region , three Stormtrooper batches were grown in the Outer Rim . In 18 BBY , Palpatine dispatched the " Eye of Palpatine " dreadnaught on a mission to destroy Belsavis ' s Plawal Rift which sheltered Ho ' Din Jedi Master Plett and the Children of the Jedi . However , the battlemoon was sabotaged by Jedi Purge survivors Geith Eris and Callista Ming . During this period , Lianna in the Tion Cluster remained the main center of operations for the pro - Imperial Sienar Fleet Systems which supplied starfighters and starships to the Imperial Navy . Around 15 BBY , Ylesia was first settled by Aruk Besadii Aora who established the Cult of The One and The All as a cover for their spice mining operations . The Abominor known as the Great Heep was also destroyed on Biitu by the efforts of R2 - D2 and C - 3PO . In 13 BBY , the descendants of the Republic - era Grizmallt colonists in the Renatasia system were rediscovered . The next year , in 12 BBY , Imperial and Centrality forces under Osuno Whett conquered the Renatasia system . In 11 BBY , Gizor Dellso ' s Separatist Remnant was defeated on Geonosis by the elite 501st Legion . Around 9 BBY , Captain Thrawn finally succeeded in crushing the decade - long Kaleesh insurgency , although with heavy casualties on both sides . As a result , the Kaleesh Bentilais san Sk ' ar joined the Imperial military . In 5 BBY , the Erhynradd Mutiny occurred . In 4 BBY Moff Sarn Shild considered seceding from the Empire and carving out his own empire in the Outer Rim territories once he tapped into the wealth of the Hutt clans . During the Firrerreo Genocide that same year , the Firrerreo Procurator of Justice Hethrir destroyed all life on his homeworld of Firrerre by unleashing a lethal strain of the hive virus . The planet was quarantined while thousands of adult Firrerreo were abducted and imprisoned in suspended animation aboard passenger freighter s . Meanwhile on Rafa IV , the activation of an ancient Sharu relic discovered by Lando Calrissian known as the Mindharp unleashed subharmonic emanations which started a reversal of social order in the Rafa system . The Toka were restored as the legendary Sharu while the pyramids crumbled , with strange , new cities emerging . This also created an interdiction field which prevented hyperspace travel in and out of the system for weeks . Many of the Human settlements had also been destroyed , and the surviving settlers fled . Trade with the Rafa system also collapsed overnight . In 3 BBY , the Imperials and Centrality attempted to exterminate the Oswaft species but were thwarted by the joint efforts of Calrissian and Vuffi Raa during the Battle of ThonBoka and the arrival of the mysterious Silentium . The Sorcerer of Tund Rokur Gepta was also slain during the battle . In 2 BBY , Han Solo and Chewbacca accidentally started the Cult of Varn amongst the insectoid Kamarian s of the desert world of Kamar who revered water . By 2 BBY , most of the Separatist holdouts in the Outer Rim had been absorbed into the newly formed Alliance to Restore the Republic , beginning the Galactic Civil War . In 1 BBY , the Mon Calamari Resistance succeeded in wresting Dac from Imperial control . However , that same year , Sriluur and Sulon were conquered by the Imperials . Meanwhile , the Rebel Alliance launched an attack on Ylesia , disrupting the Besadii clan ' s spice mining operations and freeing the slaves . With the dissolution of the Imperial Senate in 0 BBY by order of Emperor Palpatine , Moffs and Regional Governors were given direct control over their systems and sectors . That same year , the Rebel Alliance scored an important victory at Toprawa by capturing a large portion of the Death Star plans . In retaliation , the Imperials destroyed Alderaan using the Death Star . However , the Alliance scored a major victory when X - wing pilot Luke Skywalker destroyed the Death Star during the pivotal Battle of Yavin . Later that year , the Outer Rim was the site of a battle between the Alliance and Imperials . After his exile , rogue Imperial Commander Rezi Soresh spent twenty - seven days on the run before settling in the Sixela system . There he established an outpost on a barren moon . After capturing the Arkanian colony vessel " Endeavor " , Soresh used the people on board as hostages to lure the Rebel pilot Luke Skywalker to the system in order to turn him into his personal assassin . Skywalker was tortured for two weeks . Soresh also used a brainwashed spy to lure the Alliance Fleet to the star system . Contacting Darth Vader via hologram , Soresh ensured the Sith Lord would arrive at the same time as the Rebel fleet . When the opposing fleets arrived , Soresh sprung his trap , launching prototype resonance torpedo es at the system ' s Blue giant star . Skywalker betrayed Soresh and freed his companions , who participated in the battle until the torpedoes hit the sun and started a chain reaction , forcing the Rebels and Imperials to escape . Soresh was killed by Han Solo near the end of the battle . The system was turned into dust and radiation when the sun went supernova . In 0 ABY , the Alliance managed to evacuate its base on Yavin 4 despite an Imperial blockade . During the ensuing fighting , Admiral Ackbar launched a feint attack in the Vallusk Cluster to draw away Imperial forces . Meanwhile , Rebel General Jan Dodonna was captured and later imprisoned aboard Ysanne Isard ' s " Executor " - class Star Dreadnought " Lusankya " . In 1 ABY , Bakura was annexed by Imperial forces under Governor Wilek Nereus . Ore from its mineral rich moons would be used in the construction of the second Death Star above the Forest Moon of Endor in the Moddell sector . In 2 ABY , the Rebel Alliance established a new base known as Echo Base on the icy world of Hoth . In 3 ABY , Darth Vader ' s elite Death Squadron including his new flagship " Executor " launched an attack on Hoth , forcing the Alliance to retreat . Later , Cloud City in the gas giant Bespin was occupied by the Empire after Baron Administrator Calrissian defected to the Alliance . Meanwhile , Imperial Admiral Harkov ended the Sepan Civil War . In 4 ABY , the Hutt Desilijic crime family suffered a severe setback with the death of Jabba the Hutt on Tatooine at the hands of Princess Leia . Later , the Rebel Alliance scored a major victory during the Battle of Endor with the destruction of the second Death Star and the Order of the Sith Lords with the deaths of Emperor Palpatine and Darth Vader . As a result , the Rebel Alliance was reorganized into the Alliance of Free Planets with Endor as its capital . That same year , the saurian Ssi - ruu k launched an invasion of Bakura from the Unknown Regions but were repelled by the combined efforts of the local Imperial garrison and an Alliance task force under Skywalker . Bakura subsequently joined the Alliance of Free Planets . During the brief Nagai – Tof War , the Nagai and Tof invaded Endor and Iskalon but were quickly defeated and retreated back into Wild Space . New Republic era . When news of the events on Endor reached the galactic public , hundreds of worlds predominantly in the Rimward territories joined the newly formed New Republic — the successor to the Alliance of Free Planets . With the deaths of Emperor Palpatine and Darth Vader at Endor , the Imperial forces throughout the Rim were unable to put up an effective resistance against the New Republic . Across the galaxy , the Galactic Empire fragmented into squabbling kingdoms ruled by local Imperial military commanders and Moffs who established themselves as independent warlords . Admiral Gaen Drommel established a dictatorship in the Oplovis sector while Grand Moff Ardus Kaine created the Pentastar Alignment which dominated a large area of the Outer Rim . Meanwhile , Moff Getelles and Admiral Zsinj consolidated their control on the Antemeridian and Quelii sector s respectively . In the wake of Endor , the Corporate Sector ' s capitalistic regime attempted to remain neutral and sold products to both the New Republic and the Imperial warlords . The New Republic , however , was too burdened with establishing a new government to sign a long - lasting partnership with the corporate - minded fiefdom — especially since some in the New Republic considered the Corporate Sector Authority to be just as bad as the Empire . By 7 ABY , the New Republic ' s successes in securing the Outer and Mid Rim territories allowed the Republic to secure several key worlds in the Colonies and Core Worlds including Borleias and the galactic capital Coruscant itself . With the defeat of warlord Isard in the Bacta War which embroiled the Inner Rim , Republic forces were able to turn their attentions to warlord Zsinj ' s territorial ambitions in the Outer Rim . By now , Zsinj was embroiled in war against both the Republic and rival Imperial factions . During the Battle of Ession , Alliance forces under Wedge Antilles scored an important victory against the warlord ' s forces . During the Battle of Selaggis , however , Zsinj tricked Republic forces under Han Solo into believing that his flagship " Iron Fist " had been destroyed . In 8 ABY , Zsinj unleashed his orbital nightcloak satellites on Dathomir in retaliation for the Nightsisters ' failure to destroy the Singing Mountain Clan . However , the warlord was defeated in the succeeding Battle of Dathomir by a joined Republic and Hapan fleet under General Solo . With the acquisition of captured Star Destroyers supplied by the Hapes Consortium , New Republic forces under Admiral Ackbar were dispatched to the Outer Rim to finish off the scattered remnants of Zsinj ' s forces . Unfortunately , midway they were intercepted by Mid Rim warlord Treuten Teradoc who inflicted heavy casualties on the New Republic fleet , forcing a retreat to the Hast Shipyards . By the end of the standard year , the Republic controlled three - quarters of the known galaxy including large areas of the Outer Rim . The Outer Rim worlds of Dac , Sullust and Sluis Van became prominent member worlds of the New Republic within the region . However , in 9 ABY , the Republic suffered serious military reverses with the arrival of Grand Admiral Thrawn . Having returned from the Unknown Regions , the blue - skinned Chiss commander rallied the scattered Imperial forces and unleashed a military campaign against the New Republic . During the Battle of Sluis Van , an Imperial victory was narrowly prevented by the last - ditch efforts of Calrissian . On remote Wayland in the Ojoster sector , Thrawn ' s forces acquired an operational cloaking device , several Clone Wars - era Spaarti cloning cylinder s and the services of the Dark Jedi clone Joruus C ' baoth . Utilizing these resources , Thrawn launched several attacks against Republic worlds including the Outer Rim worlds of Ord Mantell and Ukio . However , Thrawn ' s Noghri commandos turned against him and he was assassinated during the Battle of Bilbringi . Despite his death , the New Republic had lost a third of its territory to Thrawn ' s Imperial forces especially in the Rimward territories . The Republic was forced to move its forces further into the Outer Rim away from the strategically important Core Worlds . Taking advantage of this , the clone incarnation of Emperor Palpatine launched a second offensive from his stronghold in the Deep Core in 10 ABY . Several key Core Worlds including the capital Coruscant were recaptured and the New Republic was forced to evacuate to Da Soocha V in the Outer Rim . Shortly afterward , Imperial forces attacked several New Republic worlds in the Borderland Regions and the shipyard world of Dac with World Devastator s to punish the native Mon Calamari and Quarren for their resistance to the Empire . Due to the efforts of Skywalker and R2 - D2 , the Devastators were defeated . In a second skirmish over Pinnacle Moon , Palpatine ' s flagship " Eclipse " was destroyed . In retaliation , he destroyed Pinnacle Moon itself with a projectile from the Galaxy Gun . The Emperor continued to launch more projectiles , destroying unruly worlds and nearly crippling the New Republic . As a result , the Empire quickly regained key territories in the Outer Rim . However , this victory was short - lived as Palpatine ' s spirit was finally destroyed during a showdown on Onderon . By 11 ABY , the Galactic Empire had yet again descended into infighting amongst the Warlords and high military officers . Still , Imperial Royal Guardsman Carnor Jax and his Interim Council controlled a thin band stretching from the Outer Rim to the Colonies . Amidst the infighting among the Council , Xandel Carivus established himself as the new Emperor on the Outer Rim world of Ord Cantrell . Tensions between Carivus and fellow Imperial Baron Ragez D ' Asta culminated in the Battle of Ord Cantrell where the former was forced to sue for peace . During this period , several Yuuzhan Vong advance agents including Nom Anor were active in stirring up local conflicts . Meanwhile , New Republic attempts in the forms of Han Solo and Chewbacca to establish contact with Kessel were met with failure . The duo only succeeded in rescuing the Force - sensitive Kyp Durron from slavery . Fleeing into hyperspace , the former Rebels stumbled upon an isolated Imperial research base known as the Maw Installation . There , they encountered Admiral Natasi Daala — one of the few high - ranking female Imperial military officers and a protégé of the late Grand Moff Tarkin . During an escape attempt , the companions made off with an experimental Imperial superweapon the Sun Crusher , capable of destroying entire stars with a projectile . Shortly afterward , New Republic forces launched a successful attack on the Maw Installation , destroying both the Sun Crusher and the Death Star prototype and forcing Daala to retreat . Daala ' s surviving Imperial forces fled to the Deep Core and succeeded in unifying the Imperial forces there . As part of his efforts in establishing a New Jedi Order , Jedi Master Skywalker established a Jedi Praxeum at the former Rebel base on remote Yavin IV . In 12 ABY , Skywalker and Jedi Purge - survivor Callista succeeded in destroying the " Eye of Palpatine " in the Moonflower Nebula . Later that year , the New Jedi Order successfully fought off two successive attacks by Daala ' s Imperial fleet and the Empire Reborn . Meanwhile , the Hutt crime lord Durga Besadii Tai attempted to construct a down - scaled version superweapon known as the " Darksaber " in the Hoth asteroid field with the assistance of former Imperial weapons designer Bevel Lemelisk . A New Republic task force including General Madine and Admiral Ackbar succeeded in destroying the " Darksaber " by driving it into the asteroid field . In the ensuing conflict , Madine was executed by Durga . Following Daala ' s defeat at Yavin IV , Daala retired and was succeeded as Supreme Commander by Admiral Pellaeon — Thrawn ' s second - in - command . Under Pellaeon , the Imperial Remnant began harassing Republic shipping in the Outer Rim and consolidated Imperial control over that region and the neighboring Mid Rim and Wild Space . The Imperial Remnant also annexed Kaine ' s Pentastar Alignment . In 13 ABY , conflict broke out on Nam Chorios between the " Oldtimer s " and the more recent group " Newcomer s . " During a diplomatic mission to Chorios , Chief of State Leia Organa Solo was kidnapped by former Republic senator Seti Ashgad . Ashgad planned to unleash a deadly infection of droch s throughout the Meridian sector called the Death Seed plague as part of a deal with Moff Getelles and the Loronar Corporation . However , their efforts were thwarted by the combined efforts of the Skywalkers , Solo , Calrissian and Daala . Later , Skywalker was able to negotiate and establish contact with the native crystalline Tsil s who agreed to help eliminate the drochs within the sector . Meanwhile , the New Republic dispatched two full fleets and invaded the Antemeridian sector . Getelles proved unable to stop them and the sector , along with much of neighboring space was captured by the Republic before Pellaeon halted their advance . In 14 ABY , Chief of State Organa Solo embarked on a diplomatic tour of several Rimward worlds with her three children Jaina , Jacen and Anakin Solo . At Munto Codru , the children were kidnapped by agents of the Empire Reborn . Their leader Dark Jedi Hethrir attempted to indoctrinate the Solo children and planned to sacrifice Anakin to the demonic Waru at Crseih Station . However , the Empire Reborn was defeated during a confrontation and the Crseih system was destroyed in the resulting supernova . With the defeat of the Empire Reborn , the Republic freed and repatriated many of Hethrir ' s former slaves including the kidnapped children on the Worldcraft " Rebirth " and the imprisoned passengers aboard Hethrir ' s passenger freighter s . At an unknown period prior to 17 ABY , former Jedi cadet Dolph overthrew the tyrannical Je ' har regime on his homeworld of Almania . Having turned to the dark side he adopted the pseudonym Kueller and established a military junta which attempted to overthrow the Republic in 17 ABY . He used rigged bombs to exterminate the populations of Pydyr and Auyemesh and then attempted to overthrow the New Republic through a mixture of subversion and terrorist attacks . After the defeat of Kueller , Alania came under the control of his chief lieutenant , Yanne , who opened diplomatic talks with the New Republic . However , Yanne was soon overthrown by Gant , who in turn was overthrown by an unstable military junta . As a result Almania remained impoverished and was never able to join the New Republic . As of 22 ABY , trade languages were common in the Outer Rim . New Jedi Order . In 25 ABY , much of the Outer Rim was devastated by the Yuuzhan Vong invasion . However , undercover Yuuzhan Vong operatives had already infiltrated various Outer Rim worlds since the Clone Wars including Belkadan , Artorias and Helska IV ; the latter becoming a base for the advanced invasion force known as the Praetorite Vong . The Yuuzhan Vong began their attack at Vector Prime in the northern quadrant . Following events in the Expansion Region , the Yuuzhan Vong Warmaster Shedao Shai authorized the use of the Yo ' gand ' s Core tactic on Sernpidal , destroying the world and killing millions . After attrition warfighting , the New Republic destroyed the Praetorite Vong base on Helska IV which hampered the Yuuzhan Vong war effort by two months . However , the Coruscant government underestimated the Yuuzhan Vong and was reluctant to commit resources to the Outer Rim . In a swift blitzkrieg , the invaders seized a string of worlds including Dubrillion , Destrillion , Dantooine , Artorias , Rychel , New Holgha and Garqi . Billions of sentients were displaced resulting in a massive refugee problem . Having seized the north - eastern quadrant of the Outer Rim and severed the Hydian Way and the Perlemian Trade Route , the newly formed Yuuzhan Vong empire then proceeded into the Mid Rim and Expansion Region as part of their campaign to seize the strategically valuable Core region . In 26 ABY , the Yuuzhan Vong invaded Hutt Space but failed to penetrate the well - defended Bootana Hutta enclave . As part of their campaign against the Jedi , the Vong and the collaborationist Peace Brigade destroyed the Jedi Praxeum on Yavin IV where they established a damutek colony . This colony became the birthplace of the Jeedai heresy which drew a substantial following among the lowly Worker caste and Shamed Ones . During a mission above Myrkr in 27 ABY , the Jedi sustained heavy casualties including the death of Anakin Solo . With the loss of Coruscant that year , the New Republic relocated to the strategically important Outer Rim world of Dac which retained its importance as a military shipyard . The new Chief of State Cal Omas had the New Republic reformed as the Galactic Federation of Free Alliances which increased the power of the judiciary over the Senate . In 28 ABY , the Galactic Alliance recaptured Ylesia from the Peace Brigade but their successes were dampened by Yuuzhan Vong victories in Barab I , Rutan and Belderone . Following an attack on Yaga Minor and Muunilinst , the Imperial Remnant entered the war on the side of the Republic , protecting its holdings on Bastion and nearby worlds . Meanwhile , the Ssi - ruuvi Imperium attempted a second invasion of Bakura with the support of the treacherous Bakuran Prime Minister Molierre Cundertol but were repulsed by the Bakurans , the Galactic Alliance and the P ' w ' eck Emancipation Movement . , The southern quadrant was not attacked while the Yuuzhan Vong limited their campaign in the Tion Cluster to seizing several fringe worlds including Caluula . In 29 ABY , the Yuuzhan Vong launched an ill - fated final offensive against Dac which the Alliance took advantage of to launch a counter - attack on Coruscant , recapturing it after prolonged fighting . The Alliance unleashed the Alpha Red bioweapon on Caluula which eliminated the Yuuzhan Vong garrison but then mutated and destroyed the planet ’ s biosphere . With the end of the war , the Outer Rim returned to the control of the Galactic Alliance while the Hutts reasserted control over their region of space . However , little central government existed in the region while the slave - trading Senex and Juvex sectors encouraged the immigration of refugees . Legacy era . About a decade after the calamity of the Yuuzhan Vong War , the Outer Rim was the site of battlegrounds for the Second Galactic Civil War , on planets such as Ossus ; however , it did not play a very important role in that conflict . In 43 . 5 ABY , when the exiled Luke Skywalker and his son traveled away from Coruscant , they found a lost Sith order in the Outer Rim as well as a huge being of dark - side energy by the name of Abeloth in the Maw Cluster . In 127 ABY , Darth Krayt ' s resurgent One Sith order collaborated with the Yuuzhan Vong pariah Zenoc Quah to sabotage the Ossus Project — a joint initiative by the Jedi and the Yuuzhan Vong to terraform several devastated worlds as a peaceful gesture . This action stirred anti - Vong sentiment which the Fel Empire — the successor state to the Imperial Remnant — took advantage of to invoke war on the Alliance . By 130 ABY , the Alliance had capitulated and the Imperials seized Coruscant . However , Krayt toppled the ruling Roan Fel and re - established the Empire as his own Sith Empire . The Jedi Academy on Ossus was a battleground of the Third Jedi Purge . Purge survivor Cade Skywalker , a member of the legendary Skywalker family , traveled through the Outer Rim in order to redeem himself . Various Rim worlds like Socorro , Daluuj , Borosk , Iego , Munto Codru and Wayland were the sites of skirmishes between the One Sith and their Jedi , Fel - loyalist and Alliance opponents . In 137 ABY , Roan Fel ' s forces recaptured Bastion and secured the surrounding space . A joint Alliance and Imperial force raided the Sith stronghold of Dac ; damaging the Mon Calamari Shipyards and capturing the Advanced Star Destroyer " Imperious " . The Sith retaliated with a genocide targeting the Mon Calamari species . After several setbacks , Darth Wyyrlok initiated the Final Protocol which authorized the poisoning of Dac ' s oceans with toxins crafted by Sith scientist Vul Isen . The toxins killed all life within the ocean world within days , prompting the Alliance and Imperials to pool their resources into organizing a mass evacuation . They succeed in evacuating 20 % of the planet ' s population including billions of Mon Calamari , Quarren , Whaladon s and Moappa but Dac was rendered uninhabitable . Piracy was rife in the Arkanis sector which became the site of a Sith ambush against Admiral Gar Stazi ' s Alliance forces . Black Sun ' s operations in the region particularly Tatooine was also smashed by the efforts of Cade and Gunn Yage . During , Sith forces attempted to ambush and capture Roan Fel at Agamar but only succeeded in capturing his daughter Marasiah Fel . Later , the Sith ' s poisoning of Da Soocha and the destruction of the Hutt Temple Maya Armus on Napdu prompted the Hutts into entering the conflict against the Sith on the side of the Alliance and Imperials . Government . Due to its distance from the Core Worlds , the influence of any galactic region was profoundly limited throughout the Outer Rim . As a consequence , communications and law enforcement in the region were limited and the various institutions of galactic civilization were little more than concepts . Various crime and atrocities went unnoticed particularly in Hutt Space , the Juvex and Senex sectors , and the Kanz sector during the Kanz Disorders . Throughout the history of the Galactic Republic , central control was limited and much of this was lost during the New Sith Wars . The Republic never regained full control over the region which was further affected by the disestablishment of the Republic Military under the Ruusan Reformations . The ensuing power vacuum was gradually occupied by the Hutts and conglomerates like the Trade Federation and Commerce Guild . Political representation of many Outer Rim worlds in the Galactic Senate was bought up by the latter while many disillusioned worlds joined the Confederacy of Independent Systems . The Clone Wars provided the opportunity for the Republic and its successor state the Galactic Empire to re - establish central albeit militarized control over the region . Throughout the Galactic Civil War , central government faltered at alternating intervals due to the fighting between Imperial forces and the New Republic . What little remained collapsed during the devastating Yuuzhan Vong War and efforts to re - establish it was hampered by the Second Galactic Civil War . Thus , much of the region was left to its own devices . Behind the scenes . In the first and second drafts of the " Star Wars " script , the Outer Rim was called the Outlands , and stretched from " the celestial equator to the farthest reaches of the Great Rift . " It was the center of resistance to the Empire .
