Teti was the first king and the founder of the 6th Dynasty. He ruled Ancient Egypt from 2323 till 2291 BC. His wife, Queen Ipwet, is the daughter of King Wenis who was the last king of the 5th Dynasty. The queen was the mother of Teti's heir, King Pepi I. Historians believe that she is the one that gave him the royal power. Almost all the major court officials of King Wenis remained in power during Teti's reign. The king was murdered by his guards for mysterious reasons. Teti granted more lands to Abydos and his name was inscribed in Hatnub. He built a pyramid in Saqqara which is called by modern Egyptians the " Prison Pyramid". Most of his reign was not documented. Egyptologists discovered a statue of him made of black and pink granite. The statue is located at the Egyptian museum. Teti's son-in-law, Mereruka, was also his vizier. The Mastaba of Mereruka is located in Saqqara.
