Thutmose I (also known as "Thothmes," "Thutmosis" or "Tuthmosis I", meaning "Thoth-Born") was the third Pharaoh of the 18th dynasty of Ancient Egypt. He became pharaoh after the death of Amenhotep I. During his reign, he sent his armies into the Levant and Nubia, pushing the borders of Egypt further than ever before. He built many temples in Egypt and a tomb for himself in the Valley of the Kings. He is the first king known to have done this, though Amenhotep I may have done it first. He was succeeded by his son Thutmose II, and then his daughter, Hatshepsut. He ruled from 1506 to 1493 BC. Some scholars give his dates from 1526 BC to 1513 BC. This depends on where the astronomical observations used to calculate ancient Egyptian dates were made. If the observations were from the city of Memphis it would give the dates 20 years earlier than if it was Thebes.
