Thutmose III (sometimes read as Thutmosis or Tuthmosis III, Thothmes in older history works, and meaning Thoth is born) was the sixth Pharaoh of the Eighteenth Dynasty. During the first twenty-two years of Thutmose's reign he was co-regent with his stepmother, Hatshepsut, who was named the pharaoh. While he was shown first on surviving monuments, both were assigned the usual royal names and insignia and neither is given any obvious seniority over the other.[3] He served as the head of her armies. After her death and his later rise to pharaoh of the kingdom, he created the largest empire Egypt had ever seen; no fewer than seventeen campaigns were conducted, and he conquered from Niya in North Syria to the Fourth Cataract of the Nile in Nubia. Officially, Thutmose III ruled Egypt for almost fifty-four years, and his reign is usually dated from April 24, 1479 BCE to March 11, 1425 BCE; however, this includes the twenty-two years he was co-regent to Hatshepsut—his stepmother and aunt. During the final two years of his reign, he appointed his son and successor, Amenhotep II, as his junior co-regent. When Thutmose III died, he was buried in the Valley of the Kings as were the rest of the kings from this period in Egypt.
