 The first royal tombs in the Valley of the Kings were those of Amenhotep I (although this identification is also disputed), and Thutmose I, whose advisor, Ineni, notes in his tomb that he advised the king to place his tomb in the desolate valley (the identity of this actual tomb is unclear, but it is probably KV20 or KV38).The Valley was used for primary burials from approximately 1539 BC to 1075 BC.It contains at least 63 tombs, beginning with Thutmose I (or possibly earlier, during the reign of Amenhotep I) and ending with Ramesses X or XI, although non-royal burials continued in usurped tombs.
