Coruscant provisional government

"In the month since the Battle of Jakku, the Empire has attempted no further large-scale offensives. Sources report all Imperial vessels within the Core and Inner Rim staying within the boundaries defined by the treaty. A few prominent members of the Provisional Senate have speculated that the New Republic's war with the remnants of the Empire has finally come to an end and that a final surrender may be imminent. However, in her address today, the chancellor warned that all planets should remain on high alert, and the New Republic Starfleet should be kept on a war footing for the foreseeable future."

In the aftermath of the Galactic Civil War, the Galactic Empire was officially dissolved and supplanted by a provisional government in the year 5 ABY. Located on Coruscant, a core world and the former capital of the Empire, the provisional government was officially led by Grand Vizier of the Imperial Ruling Council Mas Amedda. However, his administration was powerless as it was placed under the oversight of New Republic overseers; their purpose to confirm that Amedda remained little more than a figurehead.

"You&hellip;you're serious. You want me to surrender&hellip;the entire Galactic Empire?''" "That's right." "I don't&hellip;" "You don't have the power, do you?" "I&hellip;" "''So, get it back. And then bring a treaty to our door."

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. 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.

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 under the leadership of Grand Vizier Mas Amedda, who escaped from Coruscant after Rax had him imprisoned in the Imperial Palace. Amedda represented the Empire at the signing of the peace treaty known as the Galactic Concordance on the former Republic capital planet of Chandrila; its conditions requiring the former Empire to remain within the predetermined boundaries set in the Core Worlds and Inner Rim. It also prohibited the recruitment and mobilization of stormtroopers, as well as the use of torture. In addition, the Empire had to shut down the Imperial Academy system; and although they ceded control of Coruscant to the Republic, the provisional government was permitted to remain on the former Imperial capital, albeit under the surveillance of Republic overseers. Over time, political hardliners rose to dominate the internal affairs of the post-war government.

Non-combatant functionaries were pardoned by the Republic and allowed to remain part of the provisional government, but on the condition that they adhere to the terms of the treaty. As such, Republic observers were tasked with monitoring Amedda's government while the New Republic itself concentrated on restoring the rule of democracy. All surviving Imperial officials were categorized as war criminals by declaration of Chancellor Mon Mothma of the New Republic. By then, however, remnants of the Empire's once-powerful starfleet&mdash;including those led by Commander Nash Windrider&mdash;began withdrawing to the Queluhan Nebula, its ionized gases allowing them to amass a large fleet while avoiding the Republic's sensors due to the ionized gases of the nebula. Other Imperial officers and loyalists &mdash;such as Rae Sloane, Commandant Brendol Hux, and his son Armitage &mdash;along with many Imperial warlords embarked on an exodus into the Unknown Regions of the galaxy where they would ultimately establish a military junta known as the First Order.
