The important facts about her life are outlined by Professor Glasgow of Bowie, Maryland:
"Her extraordinary story begins about 1582, the year of her birth. She is referred to as Nzingha, or Jinga, but is better known as Ann Nzingha. She was the sister of the then-reigning King of Ndongo, Ngoli Bbondi, whose country was later called Angola. Nzingha was from an ethnic group called the Jagas. The Jagas were an extremely militant group who formed a human shield against the Portuguese slave traders. Nzingha never accepted the Portuguese conquest of Angola, and was always on the military offensive. As part of her strategy against the invaders, she formed an alliance with the Dutch, who she intended to use to defeat the Portuguese slave traders."
In 1623, at the age of forty-one, Nzingha became Queen of Ndongo. She forbade her subjects to call her Queen, She preferred to be called King, and when leading an army in battle, dressed in men's clothing.
In 1659, at the age of seventy-five, she signed a treaty with the Portuguese, bringing her no feeling of triumph. Nzingha had resisted the Portuguese most of her adult life. African bravery, however, was no match for gun powder. This great African woman died in 1663, which was followed by the massive expansion of the Portuguese slave trade.
