Federal Era History . the Federal Era began in 1581 BBY ( 11 , 138 Tapani calendar ) when a cadre of military officers staged a coup and placed the government of the sector into the hands of a group of reformers . The reformers that came from nearly all the noble houses formed a federation of the planets from the fallen empire . The new federal government was ruled by a Prime Minister elected by a parliament on Procopia . This system of government was more decentralized than the Imperial structure and gave more power to the individual house leaderships . The position of Prime Minister of the Tapani Federation was later elected by a Great Council . During the 15 centuries of the Federal Era , the balance of power shifted from one house to another as leaders formed Great Council coalitions that elected them to power . Most of these leaders came from Pelagia or Mecetti but from time to time even the lesser houses took charge when an effective leader rose from their ranks . Several houses rose and fell during this period in Tapani history and two left the sector entirely in search of greater opportunities . The Federal Era was also a time of change in the , at the time , backwater worlds near the Herglic border . These periphery worlds settled in the Dynastic Era were initially considered a new source of new raw materials for the high - consumption worlds of the sector . When Republic scouts opened up a new trade route circa 2203 BBY which reduced several days off the established Rimma hyperlane , however , these worlds enjoyed a huge and unanticipated surge in growth . This new route resulted in a pouring of credit and influence into the coffers of the periphery worlds that it ran through , as well as the systems along several spacelanes leading to the Shapani Bypass , leading the Great Houses to squabble over rights to the worlds . This area of space would be known as the Freeworlds Territory , as it was decided that no individual house would lay claim to any of the worlds , much like they had done with Procopia . Yet as time passed the Freeworlds began to become more and more self - sufficient and ambitious , and eventually they nationalized House interests , promptly selling them to private investors , and became fully independent of Expanse rule . A League of the five most powerful worlds was established to collude in setting tariffs , coordinating a common defense strategy , and other top level arrangements . Finally , during the Federal Era the Tapani sector joined the Galactic Republic . In 1486 BBY ( 11 , 234 Tapani calendar ) Procopia sent its first representatives to the Senate and was officially designated a sector of the Republic . Several members of House Pelagia were recruited by the Jedi Order and a bloodline strong in the Force was established . Members of the nobility frequently traveled to the Core to do business and ambassadors forged alliances and links with important Core worlds such as Alderaan and Corellia . There were many Tapani expatriates that lived on Core worlds such as Coruscant and members of the Galactic Senate enjoyed a good degree of influence and authority in galactic affairs . Although the Great Council sent representation to Coruscant the nobility generally viewed the Republic as a business necessity and looked down on the rest of civilization .
