28 February 1922 (from UK protectorate status; the revolution that began 23 July 1952 led to a republic being declared on 18 June 1953 and all British troops withdrawn 18 June 1956); note - it was in ca. 3200 B.C. that the Two Lands of Upper (southern) and Lower (northern) Egypt were first united politically.
