King of Egypt (c 1545 BC) who, according to tradition, faced unreasonable demands from the Hyksos, the west-Semitic conquerors who had overrun much of Egypt in the 17th century BC. This Theban ruler of the 17th Dynasty began the series of campaigns against the Hyksos rulers in the Delta, which were eventually to culminate in the liberation of Egypt by his son Ahmose I (1550-1525 BC), the first ruler of the 18th Dynasty. He was probably assassinated.
