Hatshepsut of Egypt

She was the daughter of Thutmose I[?]. Ostensibly regent for Thutmose III of Egypt, she gradually assumed power for herself, eventually being crowned as Pharoah. Along with it, she assumed the male trappings of power, wearing the male clothing and even false beard of the Pharaohs and having herself addressed by the male titles. She was a hands-on ruler, leading a successful military campaign in Nubia and traveling on a rich trading mission in Punt.

Hatshepsut is regarded as the first female monarch in recorded history.
