Ahmose I (Egyptian: , sometimes written Amosis I, "Amenes" and "Aahmes" and meaning Born of Iah ) was a pharaoh of ancient Egypt and the founder of the Eighteenth dynasty. He was a member of the Theban royal house, the son of pharaoh Seqenenre Tao and brother of the last pharaoh of the Seventeenth dynasty, King Kamose. During the reign of his father or grandfather, Thebes rebelled against the Hyksos, the rulers of Lower Egypt. When he was seven his father was killed, and he was about ten when his brother died of unknown causes, after reigning only three years. Ahmose I assumed the throne after the death of his brother, and upon coronation became known as Neb-Pehty-Re (The Lord of Strength is Re). The name Ahmose is a combination of the divine name 'Ah' (see Iah) and the combining form '-mose'.
