Centralized government 中央集权

A centralized government (also centralised government (non-Oxford spelling)) is one in which power or legal authority is exerted or coordinated by a de facto political executive to which federal states, local authorities, and smaller units are considered subject. In a national context, centralization occurs in the transfer of power to a typically sovereign nation state. Menes an ancient Egyptian pharaoh of the early dynastic period, credited by classical tradition with having united Upper and Lower Egypt, and as the founder of the first dynasty (Dynasty I), became the first ruler to institute a centralized government.
