Imperial Throne Room The Imperial Throne Room of the Imperial Palace on Coruscant served as the seat of the Galactic Emperor Palpatine , ruler of the Galactic Empire . That chamber was used from its construction circa 18 BBY until Palpatine ' s demise aboard the second Death Star at the battle over Endor in 4 ABY . During the Galactic Civil War between the Empire and the Rebel Alliance , Palpatine frequently summoned his trusted agents in the throne room , including Darth Vader , Mara Jade , and Xizor . History . At the end of the Clone Wars in 19 BBY , the Supreme Chancellor of the Galactic Republic Palpatine revealed his true nature as a Sith Lord and anointed himself ruler of an authoritarian Galactic Empire . He declared martial order and decreed the extermination of all Jedi , the long - time enemies of the Sith . Palpatine also ordered the refurbishment of the stately Presidential Palace , making the tallest structure on the planet of Coruscant . By 18 BBY , the changes to the Palace were completed . Several audience chambers were integrated into the building , each designed to serve a specific need . One of them served as the Palpatine ' s public throne room , where bureaucrats and honored citizens were summoned to listen to the Emperor ' s decrees . During the Galactic Civil War that pitted the Empire against the Rebel Alliance , Emperor Palpatine frequently summoned Darth Vader to his favorite throne room for important matters . Shortly before the Battle of Yavin the Empire discovered the location of the Dark Woman , a Jedi who had survived the Jedi purge . Palpatine summoned Vader in the throne room , informing him of the situation , and ordering him to travel to Cophrigin V so he could kill the survivor . Not long thereafter , the Empire ' s planet - killing Death Star battlestation was destroyed by the Rebel Alliance in the Yavin system . While trying to find the location of the young pilot responsible for the destruction of the Death Star , Vader made reports to the Emperor in the Palace throne room . Beside Darth Vader , Emperor Palpatine maintained contact with other agents in his throne room , including his elite operative Mara Jade , and Prince Xizor of the Black Sun . It is also in that room that Palpatine relieved Moff Tiaan Jerjerrod from his work in Logistics and Supply , naming him sole commander of the still - under - construction second Death Star battlestation . Layout . Sunken into the stone , the Emperor ' s primary throne room was an immense auditorium that could be divided in two sections . The first section , through which visitors entered the room , was an antechamber with curved walls and a number of stations occupied by stormtroopers . The second section was an apse that contained the throne itself , perched atop a dais . Additional stations used by members of the Emperor ' s Royal Guard jutted from the dais to either sides of the throne . Three circular windows lined with a web - like framework were located behind the throne and on both sides of it . A fourth , much larger window occupied the upper register of the back wall . At the other end of the antechamber , facing the throne , was a turbolift access that lead to the Supplicants Waiting Hall , where courtiers waited for an audience with their Imperial master .
