Queen Nzinga
Nzinga was the Queen of the Kingdom of Ndongo and the Kingdom of Matamba in the 17th century, in the area of modern-day Angola. Born into the ruling family in 1583, her father trained her in military and political tactics from a young age. While her older brother was ruling the Kingdoms, he asked Nzinga to become the ambassador to Portugal for him, as the Portuguese had begun to colonize and infringe on their native area. When Nzinga assumed power over the kingdoms after her brother died, it was during a period of unprecedented growth in the African slave trade. The Portuguese continued to agitate and break treaties, taking slaves and other valuables. Nzinga was an astute and super-intelligent leader and often bent the allegiances of the Europeans to her advantage. Forging an alliance with the Dutch, she was able to defeat the Portuguese and drive them out. She also made her kingdom a safe haven for runaway slaves. Her reign lasted 37 years - she is considered a legendary figure in Angola to this day.
Good news is, Queen Mary herself was dead 4 years later at age 42.
Karma's a b*tch.
Hmm, I'm thinking Arsenio Hall.
