Senusret I (Middle Egyptian: z-n-wsrt; /suʀ nij ˈwas.ɾiʔ/) also anglicized as Sesostris I and Senwosret I, was the second pharaoh of the Twelfth Dynasty of Egypt.

[4] 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.

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.

His main wife was Neferu III who was also his sister and mother of his successor Amenemhat II.

In his 18th year of reign Senusret I launched a military campaign against Lower Nubia and conquered the region down to the Second Cataract.

[8] Senusret I dispatched several quarrying expeditions to the Sinai and Wadi Hammamat and built numerous shrines and temples throughout Egypt and Nubia during his long reign.

He erected 2 red granite obelisks there to celebrate his Year 30 Heb Sed Jubilee.

Finally, Senusret remodelled the Temple of Khenti-Amentiu Osiris at Abydos, among his other major building projects.

Hor is known from several stelae and from an inscription in the Wadi el-Hudi where he was evidently the leader of an expedition for amethyst.

Another Antef was the son of a woman called Zatuser and was most likely also high steward in the king's reign.
