In 1618, which leader of escaped slaves gained the founding of a free village and freedom for his band of maroons, recorded as the first free Black autonomous region in the Americas, in the present day Mexican state of Veracruz?

Gaspar Yanga, originally from Gabon, was sold into slavery in Mexico. In 1570, he led the escape of slaves into the mountains of Veracruz. He and his companions lived there for nearly 40 years, supplying themselves by raids on Spanish colonists. The Spanish colonial powers went into battle but never achieved a final victory. In 1618, Yanga achieved an agreement with the colonial government for self-rule of the settlement.
