The Battle of Jakku was the decisive last stand of the Galactic Empire made on Jakku at the dawn of the era of the New Republic as it fought against the Republic following the Battle of Endor that took place in the year 5 ABY. During the waning months of the conflict, Counselor Gallius Rax assumed control of the Empire and concentrated much of its remaining forces on Jakku, an Inner Rim desert world where the Empire would make its last standoff against the New Republic.
Unknown to his own soldiers, Rax plotted to destroy the Empire in order to fulfill his obligations to the late Emperor Sheev Palpatine. However, he also intended to retreat into the Unknown Regions where he could forge a new Empire with those whom he regarded as the worthy few, such as Commandant Brendol Hux. When the Republic’s forces attacked the Empire on Jakku, Rax attempted to destroy the entire planet along with both factions. However, his efforts were thwarted by Grand Admiral Rae Sloane, who killed Rax during the battle.
While the fighting on Jakku would continue in the months that followed Rax’s death, the battle was a decisive victory for the New Republic. In the aftermath, Grand Vizier Mas Amedda and Chancellor Mon Mothma signed the Galactic Concordance on Chandrila, officially marking the end of both the civil war and the Empire itself. Following the end of the Civil War, an Imperial remnant was formed from the remaining Imperial forces on Jakku and fought against the New Republic.
