In his history of Egypt Manetho states that with the death of Unas the Fifth Dynasty came to an end. This may be because Unas died without a male heir, his probable son Unas-Ankh having predeceased him. This might have caused a succession crisis hinted at by the personal name chosen by Teti upon his accession to the throne: "Seheteptawy" meaning "He who reconciles/pacifies the two lands". Teti's claim to the throne could have relied on his marriage to Iput, who may have been a daughter of Unas. This possibility is heavily debated, as the interpretation of Iput's titles that would indicate that she was the daughter of a king is uncertain. Furthermore, the idea that Teti could legitimate his claim by marrying into the royal family is rejected by many Egyptologists, including Munro, Dobrev, Baud, Mertz, Pirenne, and Robin, who do not think that the right to the pharaonic throne passed through the female line.
