expansion into Nubia (from 1866 to 1863 BC) where he erected massive river forts including Buhen, Semna, Shalfak and Toshka at Uronarti. He carried out at least four major campaigns into Nubia in his Years 8, 10, 16, and 19. His Year 8 stela at Semna documents his victories against the Nubians, through which he is thought to have made safe the southern frontier, preventing further incursions into Egypt. Another great stela from Semna dated to the third month of Year 16 of his reign mentions his military activities against both Nubia and Canaan. In it, he admonished his future successors to maintain the new border that he had created: The Sebek-khu Stele, dated to the reign of Senusret III (reign: 1878 – 1839 BC), records the earliest known Egyptian military campaign in the Levant. The text reads "His Majesty proceeded northward to overthrow the Asiatics. His Majesty reached a foreign country of which the name was Sekmem (...) Then Sekmem fell, together with the wretched Retenu", where Sekmem (s-k-m-m) is thought to be Shechem and "Retenu" or "Retjenu" are associated with ancient Syria. His final campaign, which was in his Year 19, was less successful because the king's forces were caught with the Nile being lower than normal and they had to retreat and abandon their campaign in order to avoid being trapped in the hostile Nubian territory. Such was his forceful nature and immense influence that Senusret III was worshipped as a deity in Semna by later generations. Jacques Morgan, in 1894, found rock inscriptions near Sehel Island documenting his digging of a canal. Senusret III erected a temple and town in Abydos, and another temple in Medamud. His court included the viziers Nebit, and Khnumhotep. Ikhernofret worked as treasurer for the king at Abydos. Sobekemhat was treasurer too and buried at Dahshur. Senankh cleared the canal at Sehel for the king. Horkherty was king's acquaintance. Length of reign A double-dated papyrus in the Berlin Museum shows Year 20 of his reign next to Year 1 of his son, Amenemhat III; generally, this is presumed to be a proof for a coregency with his son, which should have been started in this year. According to Josef W. Wegner, a Year 39 hieratic control note was recovered on a white limestone block from: Wegner stresses that it is unlikely that Amenemhat III, Senusret's son and successor, would still be
