12th Dynasty

The 12th Dynasty of Egypt was the only dynasty of the Middle Kingdom in the revised history, with dynasties 7-11 and 13-14 being the First Intermediate Period, and dynasties 15-17 being the Second Intermediate Period. It followed the 13th and 14th Dynasties, and was followed by the 15th Dynasty. This dynasty lasted from 1341 to 1231 B.C., or 110 years. The occupants of the 12th Dynasty were Amenemhat I, Senusret I, Amenemhat II, Senusret II, Senusret III, Amenemhat III, Amenemhat IV, and Sobekneferu.

The dynasty began when Amenemhat I united Egypt, and appointed his son Senusret I as ruler in the south. This dynasty followed the Old Kingdom in that it had a northern and a southern portion. It was very uneventful until the reign of Senusret III, when he and his son Amenemhat III conquered Nubia together.

The final ruler of the dynasty was Amenemhat III. His son and coregent in the south, Amenemhat IV, was killed by preliminary Hyksos attacks. In an attempt to salvage the dynasty, Amenemhat III appointed his daughter Sobekneferu pharaoh with him. However, she died in the Hyksos invasion of 1241 B.C., and the 15th Dynasty began. Amenemhat III was pushed to the south where he would spend the last ten years of his life.
