Hatshepsut
Today it is generally recognized that Hatshepsut assumed the position of Pharaoh. The length of her reign usually is given as twenty-two years. The third-century B.C. historian, Manetho, gave that figure of twenty-one years and nine months, and he had access to many records that now are lost. She died in 1458 BC, which means that she became pharaoh in about 1479 BC.
