How old was Tuthmose3 when he got married to hatshepsut?

Answer 1

Since Thutmose III was too young to assume the throne unaided, Hatshepsut served as his regent. Initially, Hatshepsut bore this role traditionally until, for reasons that are unclear, she claimed the role of pharaoh. Technically, Hatshepsut did not 'usurp' the crown, as Thutmose the III was never deposed and was considered co-ruler throughout her life, but it is clear that Hatshepsut was the principal ruler in power. They didn't get married.
