Mid Rim / Legends The Mid Rim , also known as the Mid - Rim , Middle Rim , Mid - systems , or the Mid Rim Territories , was a region of the galaxy located between the Expansion Region and the Outer Rim Territories . With fewer natural resources — and therefore a smaller population — than many neighboring regions , the Mid Rim was a territory where residents worked hard for everything they had . Several planets built up impressive economies , and pirate raiders often hid in the relatively unexplored spaces far from major trade routes . Astrography . The Mid Rim was comprised of over 160 , and a region of free - standing subsectors on its southwestern flanks . History . Early Beginnings . During the Pre - Republic era , the Wookiees of Kashyyyk were ruled by the galactic - spanning Infinite Empire of the Rakata who terraformed the planet ’ s surface for agricultural purposes . The collapse of their empire left the terraforming machines unattended which resulted in the planet ’ s abnormally large foliage . The Hutt Empire encompassed a number of Mid Rim worlds including Nal Hutta and Nar Shaddaa . However , the Bothans were able to resist Hutt expansion and carve up their own independent region of space which evolved into the Bothan sector . The Mid Rim politically developed as a consequence of a colonization boom in the Expansion Region during the Great Manifest Period ( 20 , 000 — 17 , 000 BBY ) . Profits from business ventures in the Expansion Region prompted several Inner Rim political systems and religious organizations to colonize and develop the worlds in the Mid Rim ' s portion of the Slice . This colonization boom attracted few corporations which chose to remain in the Expansion Region due to the region ' s business friendly policies . Over the following millennia , colonization in the Mid Rim developed at a progressive albeit leisurely pace which provided successive generations of colonists with ample space to expand into . Due to the stronger presence of central government from Coruscant , there was less criminal activity in the region compared to the more distant Outer Rim Territories . The crime - dominated Hutt Space bordered the eastern fringes of the Mid Rim . Around 15 , 000 BBY , the factious Aqualish were discovered by the Galactic Republic following a violent first - encounter which led to the Aqualish – Republic War . Subsequently , the Aqualish joined the Republic after agreeing to abide by Republic law . In 12 , 000 BBY , Ord Mantell was settled by Corellian colonists as a Republic military outpost . Circa 8000 BBY , the Republic established an outpost on Malastare which was home to the sapient quadruped Dug species . In 7000 BBY , the reptilian Trandoshan species of Trandosha joined the Republic . In 4020 BBY , Kashyyyk was rediscovered by the Czerka Corporation , which renamed the planet " G5 - 623 " and subsequently " Edean " . Circa 4000 BBY the Mid Rim was known as the Frontier or Galactic Frontier , as it was the limit of the then explored galaxy . Most Mid Rim colony worlds became dependent on low - cost manufacturing and agriculture as the basis of their economies . However , this prosperity attracted the attention of pirates who used unexplored space as a hiding place and staging ground for raids on colonies . This became a problem in the period following the Sith Civil War . During the Mandalorian Wars , the Mandalorians considered invading Kashyyyk and using it as a training center for their troops but later abandoned such plans . Later , the Wookiee Chuundar seized power as Chieftain from his father Freyyr and banished his own brother Zaalbar . Chuundar actively collaborated with the Czerka Corporation by allowing them to exploit Wookiee slave labor in exchange for weapons . Freyyr went into self - exile to the Shadowlands of Kashyyyk . In 3956 BBY , Czerka ' s control of " Edean " was disrupted when the enslaved Wookiee populace , led by Freyyr and the former Jedi Revan , overthrew the local corporate headquarters and drove all outsiders off the planet , save from the Ebon Hawk crew . Around 3951 BBY , the Grizmalltian Queen Elsinoré den Tasia sponsored an expedition by the Republic explorer Kwilaan who discovered the planet Naboo . The planet became notorious amongst big game hunters who favored the indigenous veermoks , although it would be five decades before permanent Human settlement . Eventually , in approximately 3900 BBY , Human refugees fleeing a violent revolution on Grizmallt settled in the mountains and great grass plains . Cultural differences between the Human colonists and the indigenous Gungans led to tensions and conflict over the millennia . In 3700 BBY , the discovery of the Hydian Way encouraged colonization in the northern and southern arcs of the region . By this time , the region was organized into structured government - zoned settlement districts . Following the Great Galactic War , large portions of the Mid Rim came under the resurgent Sith Empire after the Treaty of Coruscant in 3653 BBY including loyalist worlds and species like Rodia and the Bothans . The Republic Classic era . During the New Sith Wars in 1800 BBY , Republic forces bombed the Ubese homeworld of Uba IV and exterminated all life on Uba I , II and V . This led to the near - extinction of the Ubese species who maintained an everlasting belligerence towards the Republic and the Jedi . Throughout this period , Gap Nine and Almas were the sites of battles between the Republic and various Sith factions . In the Light and Darkness War , the Brotherhood of Darkness invaded Kashyyyk and Trandosha . However , the Trandoshans slaughtered many of the troopers . The Sith retaliated by invading their world and burning the homes of the Trandoshans , leading the surviving Trandoshans to save themselves from death by pledging loyalty to the Brotherhood . In 1000 BBY , the lush world of Ruusan was the site of seven epic battles which culminated in the destruction of the Brotherhood . Following the campaign , the Republic enacted the Ruusan Reformation s which increased the powers of the Galactic Senate while reducing the number of senators . Circa 1000 BBY , Malastare was colonized by Gran colonists from Kinyen which resulted in a bloody and violent war . Using their influence in the Senate , the Gran were able to settle the conflict in their favor and established the colonial Gran Protectorate . The native Dugs were demilitarized and resettled on Malastere ' s western continent where they were exploited by their Gran colonial masters over the millennia . Throughout the last centuries of the Republic , the Gran colonists dominated Malastare . In 32 BBY , Supreme Chancellor Valorum increased taxation of Outer Rim trade routes , prompting the Trade Federation to blockade and occupy Naboo . With the support of the Jedi and the Gungans , the Naboo Queen Padmé Amidala regained control of the planet during the Naboo crisis . Meanwhile , Trandoshan terrorists attempted to assassinate the Wookiee senator Yarua in protest of their homeworld being directly represented in the Senate by Kashyyyk . In 23 BBY , further tensions between the two species led to a Wookiee blockade of Trandosha and peace talks collapsed when it was revealed that the Trandoshans were seeking to obtain representation with Trade Federation backing . In 22 BBY , the secession of various Republic worlds into Count Dooku ’ s Confederacy of Independent Systems created a flow of Loyalist refugees from Separatist worlds . The Refugee Relief Movement organized the resettlement of these refugees on ten Mid Rim worlds including Naboo , Kalarba , Monastery , Cerea , Sneeve , Bimmisaari and Durkteel . The Aqualish government on Ando also joined the Separatists but were opposed by the rival Andoan Free Colonies which remained loyal to the Republic . Due to Jedi intervention , the backwater world of Ansion remained within the Republic . Similarly , the Gran Protectorate on Malastare remained loyal to the Republic with its Senator Ask Aak serving on the Loyalist Committee . An organization called Dugs - for - Democracy opposed the Military Creation Act and fought for the civil rights of Dugs . During the Clone Wars , control of the Mid Rim fluctuated between the Confederacy of Independent Systems and the Galactic Republic . The Confederacy took advantage of interspecies rivalry between the Wookiees of Kashyyyk and the Trandoshans by arming Trandoshan commercial raiders on attacks against Republic shipping . In 22 BBY , the Separatist launched their first offensive against Kashyyyk with Trandoshan support but were repulsed by Republic forces . During the Dark Reaper campaign , the Chiss mercenary Sev ' rance Tann raided Wookiee colony on Alaris Prime . Due to its vital fuel reserves , Malastare was targeted by Separatist forces but were repulsed by local Dug forces and Republic reinforcements under Jedi General Anakin Skywalker who accidentally awakened the Zillo Beast . In 21 BBY , Separatist attempts to encourage the planets Junction V , Bezim , Delaluna and Vicondor to secede failed due to Jedi intervention . Republic forces under Anakin Skywalker also captured the Techno Union Foreman Wat Tambor on Metalorn and destroyed the Confederacy ’ s cortosis battle droid project . In 19 . 9 BBY , Armand Isard — the Director of the Senate Bureau of Intelligence — deployed mutant stone mites on the backwater world of Orleon in response to rumors of Separatist biolabs . While such rumors were later proven false , the devastation wrought by the stone mites destroyed much of the planet ’ s infrastructure ; prompting the planet ’ s entire population to emigrate offworld . In 19 BBY , Separatist forces were repulsed at Azure . Towards the end of the war , most CIS forces were repulsed to the Mid and Outer Rims . Separatist forces also launched a massive invasion of Kashyyyk in an attempt to capture the Claatuvac Guild ’ s secret archive of hyperspace routes . Republic reinforcements under Jedi Master Yoda crushed the droid army but the Jedi were then targeted for extermination under Order 66 . Under the Emperor Palpatine ’ s new Galactic Empire , Imperial forces invaded Kashyyyk and enslaved the Wookiees with the collaboration of the Trandoshans who profited in the slave trade . The Empire and Beyond . Following the Declaration of a New Order , a series of Imperial academies were established throughout the Mid Rim . It was heavily patrolled by the Empire , which feared that it was ripe for the Rebellion to set up bases there . The region ’ s interstellar markets also profited from favorable trading incentives . As the Empire withdrew from the Rim following their defeat at Endor , the Mid Rim remained one of the few places unquestionably under Imperial control . In 4 ABY , an experimental Ssi - ruuvi Hyperdrive system was discovered to have crash - landed on the planet Garos IV over 25 , 000 years before . After the Battle of Endor , it housed many hidden Imperial bases and makeshift shipyards . Many rival Moffs maintained " private empires " in this region on the condition that they supply troops and taxes to legitimate Imperial fleets in the region . During the time of the return of Palpatine in 10 ABY , the Mid Rim was still a significant Imperial power base which kept their massive fleets supplied . In 11 ABY , Palpatine ’ s final clone body and spirit were destroyed during a battle at Onderon . Following his demise , the Alliance ’ s successor state the New Republic recaptured much of the Mid Rim . By 19 ABY , the Empire had been pushed out of the Mid Rim into eighteen backwater sectors in the Outer Rim known as the Imperial Remnant . During the Caamas Document Crisis , the Bothan capital of Bothawui was the site of fighting between various pro and anti - Bothan factions . With the appearance of Imperial forces , these disparate factions united to defeat a common foe . Shortly afterwards , the Imperial Remnant and the New Republic signed the Bastion Accords which ended the Galactic Civil War . During the Yuuzhan Vong War , much of the eastern Mid Rim was invaded by the extragalactic Yuuzhan Vong . In 25 ABY , Ithor was devastated by a Yuuzhan Vong bioweapon while New Republic and Imperial forces succeeded in evacuating many refugees from Ord Mantell . In 26 ABY , the Yuuzhan Vong conquered and devastated much of the region as part of their campaign to secure the strategic Corellian Run . Several worlds including Sriluur , Druckenwell , Falleen , Ando Prime , Rodia and Ansion were conquered and occupied . Kalarba was destroyed by using the Yo ' gand ' s Core tactic to draw down its moon Hosk Station while Rodian captives were " shaped " into Vagh Rodiek warbeasts . The Yuuzhan Vong also invaded Hutt Space , capturing Nal Hutta and Nar Shaddaa . However , they failed to penetrate the well - defended Bootana Hutta region . The region was also economically wrecked due to the collapse of the local economy and trade routes . A few worlds managed to escape invasion by aligning themselves with the collaborationist Peace Brigade only to be raided by New Republic forces during the later stages of the war . With the end of the war and the recapture of the galactic capital Coruscant , those Peace Brigade worlds were unpopular with the Galactic Alliance government — the successor state to the Republic . Rejecting foreign aid , the Mid Rimmers managed to rebuild their worlds and establish new trade routes which brought a post - war boom to the region . Meanwhile , the slave - trading Senex and Juvex sectors encouraged the immigration of refugees . During the Second Galactic Civil War , Bothan Space , Bimmisaari , the Halla sector and Beris sided with the Corellian - led Confederation against the Galactic Alliance . Following a coup by Darth Caedus , Alliance forces attacked Kashyyyk for sheltering Jedi . Orbital bombardment of Kashyyyk ' s forests created a firestorm that engulfed much of the planetwide jungle and killed many Wookiees . In response , the Confederation redirected fleets from Kuat in the Core Worlds to help the Wookiees which led to the repulsion of Alliance forces . Despite Confederation assistance , the Wookiees joined the Jedi Coalition . . Following the Sith – Imperial War in 130 ABY , Darth Krayt ' s Galactic Empire seized control of much of the Mid Rim and sought to " divide and conquer " the various worlds and species . Viewing the Wookiees as a potential threat , the Sith Empire did not enslave the entire species as their predecessors but rather isolated Kashyyyk from the rest of the galaxy by destroying all spaceports and shipyards . No Wookiees were allowed to leave or visit Kashyyyk without an Imperial order and HoloNet transmissions to the planet were completely cut off . Supplies and traders still could come and go , after swearing under penalty of death not to provide Wookiees with information of the state of the rest of the galaxy , but the Wookiees themselves were completely isolated and largely left alone . In contrast , other species like the Trandoshans and Rodians prospered economically and militarily as " favored species " . The Trandoshans prospered from the redirection of trade to their homeworld while Rodian bounty hunters claimed more Jedi bounties than their rivals .
