Inner Rim / Legends The Inner Rim , also called the Inner Rim Planets , or the Inner Rim Territories , was a region of the galaxy between the Colonies and the Expansion Region . History . The Inner Rim was originally just called " the Rim " when first settled by the Galactic Republic in 20 , 100 BBY during the Great Manifest Period . It was expected to be the farthest extent of the known Galaxy for centuries , but the Expanded Rim ( later renamed the Expansion Region ) was opened within a hundred years of the Inner Rim . Due to their closer proximity to the hub of galactic civilization in the Core Worlds , Inner Rimmers gradually developed a condescending attitude towards those of the " outer galaxy " but were looked down upon by the inhabitants of the Core and Colonies . During the Pre - Republic era , several worlds in the region including Denon and Manaan were ruled by the Rakata n Infinite Empire which contained various worlds across the Galaxy . Between 5200 BBY to 4600 BBY , the jungle world of Onderon was settled by shipwrecked human colonists who established a civilization centered on the city of Iziz . In 4400 BBY , the planet was taken over by the Dark Jedi Freedon Nadd who established a Dark Side theocracy . The Naddist s expelled dissidents into the wilds of Onderon who established a new civilization known as the Beast Riders . In 4000 BBY , a Jedi mission led by Ulic Qel - Droma teamed up with the Beast Riders to overthrow the Naddists ; ending the centuries - long Beast Wars . In 3996 BBY during the Great Sith War , Mandalorian forces invaded Onderon but were decimated by Republic reinforcements while their leader Mandalore the Ultimate met his demise on the jungle moon of Dxun . For much of the Jedi Civil War , the Selkath of Manaan maintained a state of neutrality and supplied the therapeutic kolto to both the Republic and Darth Malak ’ s Sith Empire . With the decline of the kolto market and the destruction of its surface cities during the Great Galactic War , Manaan slipped into primitive decline . In 22 BBY , several Inner Rim worlds including the Givin homeworld of Yag ' Dhul joined Count Dooku ’ s Confederacy of Independent Systems during the Separatist Crisis . The Gotal homeworld of Antar 4 was the site of fighting between the pro - Republic Antarian Rangers and the Separatists . The fallout from the deployment of the electromagnetic pulse weapon that incapacitated many Gotals prompted thousands of worlds to secede and join the Confederacy . During the Clone Wars in 21 BBY , the Fourth Constitutional Amendment gave Republic worlds in the Core , Colonies , and Inner Rim more voting power than worlds in the Expansion Region and beyond . During the reign of Palpatine , the Galactic Empire ruthlessly controlled the Inner Rim . Rather than rebel , many residents chose to flee to the Outer Rim Territories . In 6 ABY , the Dark Jedi warlord Shadowspawn waged a dogged and savage campaign against New Republic forces on Mindor . In 7 ABY , Thyferra was the site of fighting between Ysanne Isard ’ s Imperial faction and Rogue Squadron over control of the production and supply of therapeutic bacta . Due to the entrenched Imperial presence , much of the region was held by the Empire until as late as 9 ABY . Subsequently , many Inner Rimmers later resented the New Republic ' s sluggishness in liberating the region . Many worlds , despite joining the New Republic , were openly afraid that the government was not strong enough to maintain power . Their concerns were borne out following the return of Palpatine in 10 ABY during Operation Shadow Hand . Following the deployment of the world - destroying Galaxy Gun against several Republic targets , the clone incarnation of Palpatine reclaimed most of the Inner Rim . With the final demise of Palpatine during the Battle of Onderon in 11 ABY , much of the region quickly fell back under the New Republic ’ s control . By the end of the Galactic Civil War in 19 ABY , the remnants of the Empire had been driven into eight barren sectors in the Outer Rim . During the Yuuzhan Vong War , the Ailon Nova Guard joined forces with the Yuuzhan Vong invaders in conquering several Inner Rim worlds including Cona , Manaan and Zeltros . However , the invaders suffered a substantial setback at the Battle of Yag ' Dhul . Following the cessation of conflict in 30 ABY , the Republic ’ s successor state the Galactic Federation of Free Alliances temporarily established its capital on Denon until reconstruction concluded on the devastated galactic capital Coruscant .
