Senusret I also anglicized as Sesostris I and Senwosret I, was the second pharaoh of the Twelfth Dynasty of Egypt. He ruled from 1971 BC to 1926 BC, and was one of the most powerful kings of this Dynasty. He was the son of Amenemhat I. Senusret I was known by his prenomen, Kheperkare, which means "the Ka of Re is created."
He continued his father's aggressive expansionist policies against Nubia by initiating two expeditions into this region in his 10th and 18th years and established Egypt's formal southern border near the second cataract where he placed a garrison and a victory stele. He also organized an expedition to a Western Desert oasis. Senusret I established diplomatic relations with some rulers of towns in Syria and Canaan. He also tried to centralize the country's political structure by supporting nomarchs who were loyal to him. His pyramid was constructed at el-Lisht. Senusret I is mentioned in the Story of Sinuhe where he is reported to have rushed back to the royal palace in Memphis from a military campaign in Libya after hearing about the assassination of his father, Amenemhat I.
