Between 1624 and 1654, the Dutch West India Company occupied part of the northeast of Brazil. A private company, in 1621 it obtained from the Republic of the United Provinces of the Netherlands a monopoly on trade and the authorization to conquer land and operate in waters on both sides of the Atlantic Ocean. It was created as a weapon against the Habsburg Monarchy, contrary to whom the Republic waged a long conflict: the Eighty Years War (1568–1648). The primary objective of the Company was to undermine the foundations of the Iberian overseas economy, which was of vital importance to the Spanish empire, and open the ports of the Spanish and Portuguese colonies to the Republic’s merchant vessels. Interest in Brazil was principally related to the possibly of making profits from sugar, tobacco, and wood for dyes, products already distributed in the Republic through direct negotiations of the Dutch in Brazilian ports and indirectly through a trade route that connected Dutch cities and Portuguese ports. Incorporated in the Spanish crown as a result of the 1580 Portuguese dynastic crisis, Brazil became the target of a military assault when trade between Brazil and the Netherlands was affected by the various embargos imposed by the Habsburg Crown. The first great attack of the Company against Brazil resulted in the capture of Salvador, seat of the general government of Brazil in 1624, but their control of the city only lasted one year, resulting in a loss for the Company. After an incredible financial recuperation due to capture of the Spanish silver fleet in 1628, the Company devised a new plan. Pernambuco was the new target. A long conflict continued until January 1654, when the government of the Company of Brazil capitulated to the Portuguese.
