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, the former capital world of the Empire, the provisional government was officially led by Grand Vizier 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.

History
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.

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 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. Among the remnants of the Empire, a provisional government was established under the leadership of Grand Vizier Mas Amedda, who represented the Empire at the signing of the peace treaty known as the Galactic Concordance. The conditions of the treaty required 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 stormtrooper forces, as well as the use of torture. In addition, the Empire had to shut down the Imperial Academy system.

All surviving Imperial officials were categorized as war criminals. Non-combatant functionaries were pardoned by the Republic, but on the condition that they adhere to the conditions 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.
