The Chancellor of the High Council is the leader of the High Council of the Klingon Empire and is the head of government for the Klingon Empire. The Chancellor became the head of government for the Empire after the fall of the post of Emperor in the mid-21st Century. The Chancellor doubled as the head of state until the restoration of the imperial throne in 2369, but retained political power. The Chancellor is protected at all times by the Yan-Isleth; in 2376, a line of Chancellor-class ships was produced by the Klingon Defense Force, each named in honor of previous chancellors.
