Ñusta Huillac was a Qulla leader who rebelled against the Spanish in Chile in 1780. She was nicknamed La Tirana (Spanish for "the Tyrant") because of her alleged mistreatment of prisoners. The term ñusta comes from the Quechuan languages and was the name for the princesses in the Inca Empire.
According to legend, she fell in love with Vasco de Almeida, one of her prisoners, and pleaded with her people for him. After her father's death, she became the leader of a group of former Incas who were brought to Chile to mine silver in Huantajaya.
