Hatshepsut was regent for her young stepson Thutmose III and then took the full titles of a pharaoh. She reigned for roughly two decades, in a period of prosperity and trade rather than conquest.
The temple was designed by Senenmut, her chief official, and built against the cliff opposite Karnak — deliberately aligned with it across the river.
Senenmut is a story in himself: a man of modest origins who accumulated more titles than almost any official of the New Kingdom, tutor to the royal daughter, with a tomb nearby whose ceiling carries one of the earliest astronomical charts known. His closeness to the female king fed gossip even in antiquity — a famous piece of period graffiti says so crudely — and speculation ever since.
The cliffs here kept one more secret: in 1881, in a tomb shaft just south of the temple, the mummies of many of the New Kingdom's greatest rulers — Seqenenre, Thutmose III, Ramesses II among them — were found stacked together, hidden by priests centuries after their burials, when the Valley of the Kings could no longer be protected.
After her death, her monuments were attacked and her name removed from king lists, apparently in the later reign of Thutmose III. The temple was later used as a Coptic monastery, which is the origin of the modern name Deir el-Bahari, meaning northern monastery.
