Senusret 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 and his wife Nefertitanen. His own wife and sister was Neferu. She was also the mother of the successor Amenemhat II. 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 at the fortress of Buhen near the second cataract where he placed a garrison and a victory stele. He also organized an expedition to a Western Desert oasis in the Libyan desert. 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 Asia after hearing about the assassination of his father, Amenemhat I.
A well known open bark shrine (known as the White Chapel) with fine, high quality reliefs of this ruler, was built at Karnak to commemorate his Year 30 jubilee; it is still on display today after being successfully reconstructed from various stone blocks discovered by Henri Chevrier in 1926. Finally, Senusret remodelled the Temple of Khenti-Amentiu Osiris at Abydos, among his other major building projects.
