Sobekneferu
Sobekneferu (sometimes written "Neferusobek") was an Egyptian woman reigning as pharaoh after the death of her brother Amenemhat IV. She was the last ruler of the 12th Dynasty and governed Egypt for almost 4 years from 1806 to 1802 BC. Her name means "the beauty of Sobek."
Family
She was the daughter of Pharaoh Amenemhat III. Manetho states she also was the sister of Amenemhat IV, but this claim is unproven. Sobekneferu had an older sister named Nefruptah who may have been the intended heir. Neferuptah's name was enclosed in a cartouche and she had her own pyramid at Hawara. Neferuptah died at an early age however.
Reign
Sobekneferu was the first known female Pharaoh for which there is confirmed proof, although Nitocris may have ruled in the Sixth Dynasty, and there are five other women who are believed to have ruled as early as the First Dynasty.
Amenemhat IV most likely died without a male heir; consequently, Amenemhat III's daughter Sobekneferu assumed the throne. According to the Turin Canon, she ruled for 3 years, 10 months, and 24 days in the late 19th century BC.
