Pharaoh Siptah (Mer-en-ptah), who's name means "Son of Ptah, Beloved of Ptah", was the son of King Seti II. He ruled the country with his stepmother Tausret as a regent.
The history of the Tomb of Siptah which measures 125 meters long is confusing. At the end of the Ninth Dynasty, after Siptah's burial, the King's cartouches were erased, then later restored in blue paint. The tomb was re-used in the Third Intermediate Period. Some excavations were made in 1905, 1912, and 1916, but they were thwarted because poor quality bedrock posed structural problems. Recently some excavations have been attempted.
