Siptah was the seventh ruler of Dynasty 19, a son of Sety II and a secondary queen, Tia'a. He became ruler after the official heir, Sety-Merenptah, predeceased his father. Because of Siptah's young age, his step-mother Tausert became regent of the country. Siptah died during his sixth reignal year. He was buried, probably with his mother Tia'a, in the unfinished KV 47. In 1898, his mummy was found in KV 35, which was reused as a cache.
