As theSwtor CreditsRepublic thrived, more worlds joined the Republic following the Mandalorian Wars and the Jedi Civil War. Unbeknownst to the Senate or the Jedi High Council the hidden Sith Empire had already infiltrated the ranks of the Senate and the Jedi Order in perparation for their return. When the Sith did return, Coruscant was taken unawares and the Empire struck at the Senate District, blackening the facade of the Republic Executive Building and leveling the nearby Jedi Temple. With the security command center in the Temple crippled, Sith forces swept through the Senate and Supreme Chancellor Berooken was executed by Darth Angral. With the Chancellor dead and Coruscant defenseless, the Republic was forced to sign the Treaty of Coruscant and broker peace with the Empire. With the treaty signed, the Empire immediately withdrew from Coruscant and the rebuilding process begun. Over the course of the next week, an enraged Jedi Master called Dar'Nala orchestrated a bombing at the Senate building, blasting apart the upper levels from the inside and killing targeted senators who backed the treaty with the Sith. The attack was designed to reincite the hatred of the Sith and lead the Republic back into war; the plot was revealed by Dar'Nala's former Padawan, Satele Shan, and the peace was kept. As Interim Chancellor Paran Am-Ris took the reigns of the Senate, repairs were made to the Senate Building while funds could not be diverted to the rebuilding of the Jedi Temple.
Following the end of the Swtor Gold War with the Sith Empire, the Republic began to thrive once more; the Jedi Temple began reconstruction and worlds ravaged by the Sith were rehabilitated. Peace reigned in the Republic until the devastating battle at Mizra between the Republic and a new breed of Sith. The loss for the Republic ushered in the begin of the New Sith Wars and the Republic Dark Age. Jedi began taking up the mantle of Supreme Chancellor, an unprecedented move by the Order as the Jedi tried to keep the increasingly shrink Republic intact. After four centuries of Jedi rule, Tarsus Valorum was elected Chancellor, the war was ended and the Brotherhood of Darkness routed, and the Senate passed the Ruusan Reformation to bring the Republic back in line.
At the Buy Swtor Credits close of the Republic's Golden Age, the Vote of No Confidence in Chancellor Finis Valorum was accepted by the Senate and Senator Palpatine of the Chommell sector became Chancellor. During his term, the Separatist Crisis tore the Republic apart; as more worlds broke away, tensions rose. Dark Jedi Granta Omega attacked the Senate during this time, killing several senators with a dangerous air-borne toxin developed by scientist Jenna Zan Arbor. Eventually the conflict in the Senate evolved into the Clone Wars. As thousands of star systems withdrew from the capital and the Jedi Order suffered Grievous losses in the war, arguments in the Senate chamber became as heated as the Republic's battlefields. After three years of death and destruction in the name of peace, Chancellor Palpatine announced the end of the war and the Declaration of a New Order, the first Galactic Empire. Disbanding the Jedi Order, Palpatine, in fact the mysterious Dark Lord of the Sith Darth Sidious' alter-ego, was confronted by the Order's Grand Master, Yoda, in the Grand Convocation Chamber. Hurling over a dozen repulsorpods with the Force and damaging countless others during the confrontation, the newly christened Emperor Palpatine emerged victorious and Yoda fled into exile.
