Thutmose I was the third pharaoh of the Eighteenth Dynasty of ancient Egypt, ruling from around 1506 to 1493 BCE. He is known for expanding Egypt's territory through military campaigns into Nubia and Syria, establishing Egypt as a powerful empire. His reign marked significant developments in architecture and art, including the construction of impressive temples. Thutmose I was also the father of Hatshepsut, who would later become one of Egypt's most famous female pharaohs. He was buried in the Valley of the Kings, and his legacy includes the establishment of a strong foundation for future pharaohs to build upon.
