Empress Gao was an empress of the Chinese/Xianbei dynasty Eastern Wei -- a branch successor state to Northern Wei. Her husband was Emperor Xiaojing, Eastern Wei's only emperor. She was the second daughter of the paramount general Gao Huan, who, after a formal break with Emperor Xiaowu of Northern Wei in 534, made Emperor Xiaojing, then age 10, emperor, thus dividing Northern Wei into Eastern Wei and Western Wei.
