Outer Rim Territories The Outer Rim Territories , also known as the Outer Rim or Outer Systems , was a sparsely populated region of the galaxy located outside the Mid Rim before Wild Space and the Unknown Regions . The largest region in the galaxy , it was home to diverse worlds and rugged , primitive frontier planets . History . Days of the Old Republic . With the formation of the Old Republic and the bustling Core planet of Coruscant being homeworld to the pioneering human species , galactic expansion occurred along trailblazing new hyperspace route s emanating outwards from the Core Worlds , with colonist s heading towards the Outer Rim in search of opportunities and a better life . Owing to economic and legal restrictions , coupled with political repression , many chose to live beyond the civilizing grasp of the Core . Navigational beacon s set up by Republic survey teams such as in the Tertiary Usaita system aided travelers heading towards the galactic periphery . The comet Kinro was predicted to carve a path through the Core Worlds , but was eventually stopped by the Jedi before it even entered the Mid Rim . Eventually , tensions arose between the Republic and its Jedi allies over the warrior culture of of the Outer Rim world of Mandalore , leading to a destructive conflict that ultimately saw the theft of the Darksaber from the Jedi Temple . While the Sith following their birth in the Hundred - Year Darkness eventually collapsed from continual infighting , resulting in Darth Bane enacting the Rule of Two , while he and other Sith Lord s were buried in the Valley of the Dark Lords on Moraband . Clone Wars . With the collapse of the Old Republic roughly a thousand years before the Clone Wars , its successor state , the Galactic Republic , remained one of the dominant galactic powers of the millennium , with trade and galactic commerce booming between the Core and Outer Rim Territories . Republic Judicial Forces and the Jedi Order enforced order throughout the galaxy , preventing a major galactic war for centuries . Several years before the Clone Wars , those in the Outer Rim eventually came to believe themselves victims of economic and social injustices , as Judicial s were often withheld in intervening in Outer Rim affairs after many far - flung worlds refused to provide the Core with profitable deals . Harassed by numerous pirate s and lacking protection from a federal military , the Outer Rim world of Eriadu formed the Outland Regions Security Force for the protection of the Seswenna sector . Funded by off - world loans and composed of an amalgam of ships , it received weapons from arms merchant s who had for centuries been ignoring a Republic ban on the sale of weapons to member worlds . Initially lacking major success , it came to the forefront after Wilhuff Tarkin joined its anti - piracy task force , in which he was able to significantly reduce pirate raids throughout neighboring systems . With the monolithic Trade Federation slowly encroaching on the Outer Rim and the perceived weakness of Supreme Chancellor Finis Valorum , who was already embroiled in numerous scandals and unable to bring the growing corruption in the Galactic Senate under control , Governor Tarkin of Eraidu turned Valorum from investigating a trade summit in an effort to weaken his authority . Ending in a disaster , the summit hastened the Trade Federation ' s Invasion of Naboo over the recently proposed the taxation of the Free Trade Zone s and disputes over plasma exports . With increasing dissatisfaction over years of neglect from the Core Worlds , dashing political idealist Count Dooku managed to foment political turmoil on worlds such as Kashyyyk , Sullust and Onderon . He eventually hijacked a HoloNet station in the Raxus system to voice his opinion . This precipitated the Separatist Crisis , which would see thousands of worlds leave the Galactic Republic and join the growing Confederacy of Independent Systems . After the Battle of Geonosis , the deadly three - year Clone Wars engulfed the galaxy and resulted in billions dead on both sides of the conflict . The Republic was forced to raise the Grand Army of the Republic to combat the Separatist threat , with the war finally ending following the Outer Rim Sieges and the death of the Separatist Council on Mustafar . Meanwhile , Chancellor Palpatine transformed the Republic into the First Galactic Empire , wiping away the thousand - year - old democracy — and the Jedi Order — in an instant . Imperial Era . The budding Galactic Empire saw increasing attempts of control of the Outer Rim . Believing control of the galaxy ' s outer systems would stabilize and secure the galactic center , Galactic Emperor Palpatine oversaw the continual military buildup of the Imperial Military and ruthlessly quash dissent and remaining Separatist holdouts across the Outer Rim . Worlds such as Jelucan and Lothal saw Imperial occupation and development , often leading to rampant pollution and industrialization to support the Imperial war machine , while men and women would be conscripted to join the Imperial Army and Navy . A ' five - year plan ' was implemented for numerous Imperial - occupied worlds under the supervision of Imperial Outer Rim High Command . In the farthest reaches of the Outer Rim , the Empire barely bothered to patrol its territory , and local citizens ' militias took it upon themselves to protect friendly convoy s . Never being able to fully control the Outer Rim , the Empire would often utilize its worlds as testing grounds for new biological weapons and as a source of labor , brutally wiping out the Outer Rim world of Lasan of its native species and exploiting the native Twi ' lek species of Ryloth by rounding up native villagers for slave labor . Seeking to embody the spirit of the Tarkin Doctrine , the Empire oversaw the construction of the first Death Star over Geonosis and exterminated the native Geonosian population . Grand Moff Tarkin was tasked with imposing order in the Outer Rim Territories , being promoted to Governor of the Outer Rim . After limiting the HoloNet of various Outer Rim worlds to Imperial use five years after the formation of the New Order , many dissatisfied systems viewed the embargo as the unofficial start of the Imperial conquest of the Outer Systems . Eventually , a growing rebel network would cause worry to the Ruling Council , and would see the formation of the Alliance to Restore the Republic and its subsequent bases on the worlds of Dantooine and Yavin 4 . With the dissolution of the Imperial Senate , Regional Governors were given oversight of their subsequent sector s and systems . Luke Skywalker from Tatooine ultimately destroyed the Empire ' s planet - killing battle station in the Battle of Yavin after its plans were stolen nineteen years after the Order ' s political formation . The Outer Rim Territories would become embroiled in the Galactic Civil War , with the Alliance Fleet dispersed across the region and the Empire fortifying the border of the Mid Rim against the lawlessness of the outlying systems . Due to its distance from the Core , unauthorized holofeeds operated in abundance in the Outer Rim owing in part to the Empire ' s tentative control of the region . After the Mid Rim Retreat , the Empire discovered the Rebellion ' s new base on Hoth , destroying it in the Battle of Hoth and splintering the Rebellion into fragments spread across the Outer Rim . Following Operation Ringbreaker , roughly six months after the Battle of Hoth , Operation Yellow Moon allowed the scattered Rebel Fleet to converge over Sullust to strike on the Empire ' s new Death Star under construction over Endor . Its destruction in the Battle of Endor saw the fragmentation of Imperial authority , resulting in the gradual retreat of Imperial dominion from the Outer Rim . New Republic . The New Republic admitted Akiva as the first Outer Rim world to formally join the Republic in the months after Endor . By 5 ABY , the Empire had lost control of much of the Outer Rim with the exception of Zhadalene , Korrus , and Belladoon . Under the orders of Fleet Admiral Gallius Rax , the Empire nationalized the Imperial weapons and vehicular factories there for the war effort . In coordination with Imperial fleets hidden in the Vulpinus Nebula , the Almagest , the Recluse ' s Nebula , the Queluhan Nebula , the Ro - Loo Triangle , and the Inamorata , Rax planned to use the three Outer Rim holdouts as a cord to strangle the New Republic . Shortly before the Battle of Jakku , Prince ss Leia Organa reported that Tatooine and Horuz were in the thrall of some Imperial remnant , criminal syndicates or gangster s . The Red Key Raiders tried to take over Tatooine but were opposed by Cobb Vanth , the elusive Mayor and Sheriff of Freetown . In 28 ABY , New Republic member worlds included Arkanis and Daxam IV , which were aligned with the Centrist faction in the Galactic Senate on Hosnian Prime . The Outer Rim planet Ryloth chose not to join the new galactic government . The planet Pamarthe was known for producing pilot s . The New Republic took steps to control organized crime by introducing new financial regulations and patrolling the major shipping lines . However , organized crime later returned to the Gaulus sector and adversely affected the economy of Ryloth due to the indecisiveness of the Galactic Senate . One major crime syndicate was the Nikto crime lord Rinnrivin Di ' s cartel , which was based on Bastatha . Rinnrivin ' s smuggling activities took a toll on Ryloth ' s economy and precipitated a New Republic senatorial investigation led by Organa and Ransolm Casterfo . In truth , Rinnrivin ' s cartel was a criminal front organization set up by several Centrist senators including Lady Carise Sindian to bankroll the Amaxine warriors and the First Order ' s fleet . The planet Daxam IV was the site of an Amaxine base which housed a thousand Amaxine warriors . The Amaxines were a militia that was led by former Imperial officer s like Arliz Hadrassian , who admired the Old Empire and sought to overthrow the New Republic . The organization was largely destroyed when an explosion destroyed their main base on the Expansion Region world of Sibensko . Rise of the First Order . Shortly before the attack on Tuanul , the First Order operated a mining operation in Pressy ' s Tumble , an artificial asteroid field in the Pressylla system . The former stormtrooper Finn and his commanding officer Captain Phasma took part in suppressing a strike at Pressy ' s Tumble . The planet D ' Qar in the Ileenium system hosted the Resistance ' s base of operations . Following the Battle of Takodana , the First Order tried to destroy D ' Qar with its Starkiller Base superweapon . However , the Resistance destroyed Starkiller Base before it could fire its superlaser . Before the Resistance could complete their evacuation of D ' Qar , they were attacked by the First Order Navy . Despite destroying a " Mandator IV " - class Siege Dreadnought , the Resistance lost several bomber s and starfighter s . Fleeing through hyperspace , they were pursued by the First Order Navy including Supreme Leader Snoke ' s flagship " Supremacy " , which was equipped with a hyperspace tracker . The Resistance operatives Finn and Rose Tico traveled to the planet Cantonica to recruit the Master Codebreaker to disable the First Order ' s hyperspace tracker . However , their mission went awry , and they were only able to recruit the criminal slicer DJ . After abandoning the Resistance flagship " Raddus " , the Resistance evacuated in U - 55 orbital loadlifter s to the planet Crait . However , the Resistance were betrayed by DJ , who revealed the Resistance ' s plans to the First Order . Despite sustaining heavy casualties , five of the Resistance loadlifters managed to regroup on Crait due to Vice Admiral Amilyn Holdo ramming the " Supremacy " with the " Raddus " . After killing Snoke , Kylo Ren claimed the mantle of Supreme Leader and led an assault against the Resistance on Crait . However , the Resistance escaped offworld due to Luke Skywalker ' s final stand with Ren . Government . Due to its distance from the Core Worlds , the Outer Rim lacked a stable , central authority to maintain order across the vast expanses of space in the region throughout its history . As a result , numerous crime families such as the Hutt Clan and Pyke Syndicate operated with impunity in the region , with slavery being common despite a Republic ban on its practice .
