About Grand Chancellor

The grand chancellor, also known by its Chinese name as zaixiang is a generic blanket title identifying the highest-ranking ministers wielding both formal and actual authorities in the imperial Chinese government. Such ministers' titles varied over time and their responsibilities and actual authorities fluctuated widely throughout Chinese history, even within a particular dynasty or within the reign of a particular emperor. During various periods, two or three ministers/titles would be recognized jointly as the grand chancellor at any given point, either exercising authorities in commission with each other or each with authorities over a broad range of functions.
