Usurtasen II. reigned for nineteen years. He does not seem to have associated a son, but was succeeded by another Usurtasen, most probably a nephew. The third Usurtasen was a conquering monarch, and advanced the power and glory of Egypt far more than any other ruler belonging to the Old Empire.

The great official, who is named Khnum-hotep, receives the foreigners, accompanied by an attendant who carries his sandals and a staff, and who is followed by three dogs. A scribe, named Nefer-hotep, unrolls before his master a strip of papyrus, on which are inscribed the words, "The sixth year of the reign of King Usurtasen Sha-khepr-ra: account rendered of the Amu who in the lifetime of the chief, Khnum-hotep, brought to him the mineral, mastemut, from the country of Pit-shu—they are in all thirty-seven persons." 

Usurtasen, after reigning ten years in conjunction with his father and thirty-two years alone, associated his son, Amenemhat II., who became sole king about three years later. His reign, though long, was undistinguished, and need not occupy our attention. He followed the example of his predecessors in associating a son in the government; and this son succeeded him, and is known as Usurtasen II. 

It was through his sculptures and his architectural works that the first Usurtasen made himself chiefly conspicuous. Thebes, Abydos, Heliopolis or On, the Fayoum and the Delta, were equally the scenes of his constructive activity, and still show traces of his presence.
