Relatively little is known about the history of the tomb. Seti II was buried there, but he may have originally been buried with his wife Twosret in her tomb in KV14 and subsequently moved to the hastily finished KV15 tomb, perhaps by the later pharaoh Setnakhte, who took over KV14 for his own tomb.[2] Seti's name appears to have been carved, erased and then re-carved. Amenmesse or possibly Siptah may have been responsible for the erasure, while Twosret may have had Seti's name restored.[2] Seti's mummy was later moved to the mummy cache in tomb KV35; only the lid of his sarcophagus remains in KV15.[2]
