Coruscant provisional government In the aftermath of the Galactic Civil War , the Galactic Empire was officially dissolved and a provisional government was set up on Coruscant , a core world and the former capital of the Empire , in the year 5 ABY and officially led by Grand Vizier Mas Amedda . However , Amedda ' s administration was powerless as it was placed under the supervision of Republic overseers ; their purpose to confirm that Amedda remained little more than a figurehead . History . Origins . In 4 ABY , Emperor Sheev Palpatine was killed in the Battle of Endor . Without the Emperor , the Galactic Empire splintered into various political and military factions such as Governor Adelhard ' s domain in the Anoat sector . At the same time , the Rebel Alliance capitalized on its victory at the Battle of Endor , reforming into the New Republic while Imperial authority increasingly diminished across the galaxy . Coruscant meanwhile had dissolved into a state of civil war with Imperial forces under Grand Vizier Mas Amedda fighting Rebel factions attempting to take control of the Federal District and other government sectors . However , it was Fleet Admiral Gallius Rax who assumed " de facto " control of the Empire , forcing Amedda to become a figurehead whom Rax used for propaganda and kept imprisoned in the Imperial Palace . Formation . Within a year of the Emperor ' s death , the Empire was decisively defeated by the New Republic at the Battle of Jakku , resulting in the death of the usurper and Counselor to the Empire Gallius Rax . Though a few Imperial remnants continued to persist in their resistance , the Galactic Civil War came to an end in 5 ABY . Following the dissolution of the Imperial government , a provisional government was established on Coruscant — the capital planet of the former Empire — under the leadership of Mas Amedda . The Grand Vizier represented the Empire at the signing of the peace treaty , known as the Galactic Concordance , on the former Republic capital of Chandrila , an event announced by the Republic to various sector s — such as the Velcar sector , where Governor Ecressys had already fled in advance to the Western Reaches with the wealth of hundred of worlds — across the galaxy . The conditions of the Concordance required the Empire to remain within the predetermined boundaries set in the Core Worlds and Inner Rim , reducing it to a rump state . It also prohibited the use of torture as well as the recruitment and mobilization of stormtrooper s , reducing the Empire ' s once - vast military through severe disarmament treaties and war reparations . In addition , the Empire had to shut down the Imperial Academy system ; and had ceded control of Coruscant to the Republic , with a planetary provisional government being permitted to form on the former Imperial capital while the remaining old establishment relocated to Imperial - held territories . As such , Republic observers were tasked with monitoring Amedda ' s government while the New Republic itself concentrated on restoring the rule of democracy . Others fled into hiding after all surviving Imperial officials were categorized as war criminals by declaration of Chancellor Mon Mothma of the New Republic . Among the officer s who eluded capture by the Republic was Nash Windrider , a commander who withdrew to the Queluhan Nebula along with remnants of the Imperial Navy . Despite its size , the fleet was able to hide its presence from Republic sensor s by using the nebula ' s ionized gas es for cover . Other Imperial officer s and loyalists — such as Rae Sloane , Commandant Brendol Hux , and his son Armitage — along with noble s , technologists , and warlord s embarked on an exodus into the Unknown Regions of the galaxy where they would ultimately establish a military junta known as the First Order . Organization . The provisional government of Coruscant was a powerless regime led by a nominal leader ; the grand vizier of the former Galactic Empire , Mas Amedda retained his position for his part in ending the Galactic Civil War . By design of the New Republic , however , he would only serve as a figurehead overseen by Republic officials . Coruscant was in a state of turmoil at the time of the provisional government ' s formation , having experienced a decline in public order and the planetary civil war that followed in the wake of Emperor Palpatine ' s death . Behind the scenes . Mas Amedda ' s provisional government was first mentioned in the canon novel " " , which was written by Chuck Wendig and released in 2017 .
