Dynasties in Chinese history, or Chinese dynasties, were hereditary monarchical regimes that ruled over China during much of its history. From the inauguration of dynastic rule by Yu the Great in circa 2070 BC to the abdication of the Xuantong Emperor on 12 February 1912 in the wake of the Xinhai Revolution, China was ruled by a series of successive dynasties. Dynasties of China were not limited to those established by ethnic Han—the dominant Chinese ethnic group—and its predecessor, the Huaxia tribal confederation, but also included those founded by non-Han peoples.
