During the Cold War the Jedi Ki Sazen participated in the signing of the Treaty at Bresnan.
Millennia later, Bresnan was the location of the Wellte-ir Massacre during the Galactic Civil War, prior the Battle of Yavin. Fifteen of twenty-one members of the Rebel Alliance's Scandium Team were lost on the plains of Bresnan, including Nyik, and Tor'ara; Commander Dutra Zeneta, Korgath, Rith Tar'ak, Opit-Wenbruh, Aven Cholus, and Harovan Toth were the six surviving Special Forces infiltrators.
