He was a son of Ahmose I and Ahmose-Nefertari, but had at least two elder brothers, Ahmose-ankh and Ahmose Sapair, and was not expected to inherit the throne. However, sometime in the eight years between Ahmose I's 17th regnal year and his death, his heir apparent died and Amenhotep became crown prince. He then acceded to the throne and ruled for about 21 years.Manetho - translated by W.G. Waddell, Loeb Classical Library, 1940, p.109
