Second king ('c.'1965 - 1920 BC) of the 12th Dynasty, son and successor of Amenemhat I after he was murdered (see the 'Teachings of Amenemhat' and the Tale of Sinuhe). Senwosret I maintained diplomatic contacts with Syria and Palestine, but also conquered part of Nubia and stationed a border garrison near the fortress of Buhen. He also undertook expeditions to the west in order to ward off the threat of invasion from Libya. Many temples all over Egypt were expanded during his reign and decorated with texts and representations. Senwosret I was buried in a pyramid at Lisht, close to the residence of the time, 'Itjitawy'.
