Galactic Alliance Senate The Galactic Alliance Senate or Galactic Alliance Assembly was , during the time of the Galactic Federation of Free Alliances , the leading legislative body of the galaxy . The Senate was the successor of the New Republic Senate of the New Republic . The Alliance Senate met in the Senate Building on Coruscant as did its predecessors . In comparison to the Galactic Senate of the Old Republic and the New Republic Senate , the Galactic Alliance Senate possessed greatly reduced executive functions and acted primarily as the government ' s legislative organ . History . Early days ( 28 ABY - 29 ABY ) . The Galactic Alliance Senate was the ruling body of the Galactic Federation of Free Alliances , succeeding the New Republic Senate and was led by a Chief of State . The Alliance and its governing body were temporarily based on Denon following the culmination of the Yuuzhan Vong War , but five years later , it had been relocated to the traditional galactic capital of Coruscant . The Galactic Alliance was reorganized from the New Republic by Chief of State Cal Omas in the final years of the war against the Yuuzhan Vong , largely in response to the corruption within the government that allowed the Vong to steadily defeat the Republic . Omas ' reorganization of the system of government saw a greater level of separation of powers . The office of the Chief of State was installed with a majority of the executive responsibilities previously possessed by the New Republic Senate . As a result the Galactic Alliance Senate held few executive powers , while maintaining all of their legislative functions , causing it to become little hindrance in the Alliance ' s war effort against the Vong , as its predecessor had been to the New Republic . In addition , by bringing the Imperial Remnant and the Hapes Consortium into the fold , the Alliance achieved what no other government since the Old Republic had achieved ; a unified galactic government . The Alliance was also originally built on strong relations with the New Jedi Order ; allowing six of its members to serve on the High Council which was formed to advise the Chief of State on directing the war effort . The High Council also included several high ranking Senators and military officials . The Alliance , under Chief Omas , ultimately proved victorious in the war ; indeed , it could be said that the reorganization of the New Republic into the Alliance was instrumental in ensuring victory in the face of defeat . Reconstruction . With the war over , the Senate and the Alliance began financing huge reconstructive efforts . With executive duties largely in the hands of the Chief of State , the New Jedi Order seemed to advise him directly , rather than acting as responsible to the Senate as the Old Order had . The Senate was located on Denon for a time , though by 35 ABY had relocated to Coruscant . Dark Nest Crisis ( 35 ABY — 36 ABY ) . With the rediscovery of the Killik s came the destructive effects of the Dark Nest ' s black membrosia . Confounded by the death of Supreme Commander Sien Sovv in an incident involving membrosia , relations between the Alliance government and the Killik Colonies soured . This also caused rising tensions with the New Jedi Order , who permanently withdrew from the High Council , in favor of creating a more centralized Jedi High Council to take formal control of the Order . As such , the Galactic Alliance Advisory Council , including several Senators , became Chief Omas ' official advisory board . Ultimately , the Jedi Order and the Galactic Alliance Defense Force proved able to defeat the Dark Nest , quelling the Killik ' s and restoring peace to the galaxy for a short time . Second Galactic Civil War ( 40 ABY — 41 ABY ) . In the midst of tensions between Corellia and the Alliance , Chief Omas created the Galactic Alliance Guard , whose leader Jacen Solo was granted extraordinary powers by the Senate so as to allow the GAG to successfully fulfill their purpose . Solo who was in fact a fledging Sith Lord manipulated the Senate , similarly to Palpatine decades earlier , into granting him emergency powers . Using a power granted to him by the Senate , Solo was able to remove heads of state ; including Chief Omas himself if they became a threat to the Galactic Alliance . After obtaining evidence that Omas was committing treason , Solo removed him from office . Solo ' s ally Cha Niathal was then promoted to Chief of State and instituted a joint - Chief system ; allowing the Sith Lord to rule the Alliance along with her . Niathal ultimately became disturbed by Solo ' s extreme tactics however , and created a breakaway Alliance - in - exile which joined the Jedi Coalition in a bid to defeat Solo , now known as Darth Caedus . With Caedus ' death , the Senate agreed to the ascension of Natasi Daala as the new Chief of State , and continued to act as the legislative organ of government under her . Powers . There were substantial differences between the Galactic Alliance Senate and the Old and New Republic Senate s , making it similar to the Imperial Senate . The Alliance Senate simply elected and had oversight of the Chief of State , but it had little say in the actual executive branch . It ' s role was confined to simply legislative . Also , there was an independent judiciary , which was intended to keep some of the more corrupt members of the Senate in line . They did , however , rely on the New Jedi Order ' s High Council for advice . Despite these new limits , and even at this early stage , the more greedy and selfish politicians and bureaucrats were already becoming adept at manipulating the Senate , forcing the Jedi Knights under Luke Skywalker ' s direction to spread themselves thin across the Galactic Alliance to settle disputes of all kinds . Composition . The Senate was headed by the Chief of State alongside the Chair of the Senate . It mainly consisted of representative assemblymen . Primary members are represented in the Senate by a governor - delegate , or Senator . Each Senator has a single vote , regardless of the population represented . Affiliate members are represented on Coruscant by a Legate , who may speak in general sessions of the Senate , but may not vote on official Senate business ( to avoid dual representation ) or serve in the Senate ' s various working bodies . The Inner Rim Caucus was a political faction in the Senate .
