The Captaincies of Brazil (Portuguese: Capitanias do Brasil) were captaincies of the Portuguese Empire, administrative divisions and hereditary fiefs of Portugal in the colony of Terra de Santa Cruz, later called Brazil, on the Atlantic coast of northeastern South America. Each was granted to a single donee, a Portuguese nobleman who was given the title captain General.
Beginning in the early 16th century, the Portuguese monarchy used proprietorships or captaincies—land grants with extensive governing privileges—as a tool to colonize new lands. Prior to the grants in Brazil, the captaincy system had been successfully used in territories claimed by Portugal—-notably including Madeira, the Azores, and other Atlantic islands.
