The Galactic Federation of Free Alliances, also known as the Federal Galactic Republic, but most commonly the Galactic Alliance, was the galactic government directly following the New Republic. Incorporating most of the known galaxy, the Galactic Alliance was the first government to achieve this since the Galactic Empire. Between 2373 and 2374 NE, the term New Order was applied to the Alliance for a short period of time. The rest of the time it was referred to as the Old Order. It replaced the New Republic after the first war and a major player in the Second Multiverse War.
Governmental changes between the New Republic and the Galactic Alliance included a new constitution, a stronger judicial branch, and a better system of checks and balances that curbed the power that had been almost exclusively in the hands of the Senate. The new federalism properly defined the roles between the government and its member worlds.
The Galactic Alliance government was led by a Chief of State and a High Council that consisted of Jedis , Senators, and members of the Alliance's military and governmental leadership. The Jedi later withdrew from the High Council in favor of forming their own leadership body; the Jedi High Council. As such, the Alliance created an Advisory Council to replace the High Council.
The new alliance was a federal republic, properly defining the roles of both the federal government and the member worlds and states. A stronger federal system was the largest change in the overall structure of the government following the dissolution of the New Republic.
