The first female pharaoh, Hatshepsut, was a noble and powerful leader even though she was a woman.
Hatshepsut was different, she didn't want to conquer lands she instead wanted to enrich Egypt by building and helping Egyptians.
After she died...
In order for people to accept her as pharaoh, Hatshepsut began to dress like a pharaoh. She even wore a fake beard and a short kilt like the men wore.
What really happened to cause this...
She had a husband (her half-brother) and he died when he was 56, though she had a step-son (Thutmose III) that couldn't rule due to his age. That is why she became Egypt's first female pharaoh for an act of regent.
Little things remained surprisingly because usually there would be a lot that remained, though archaeologists found out that someone almost erased her from history.
Though, the one who almost erased her from history might have been Thutmose III, her son in law.
