The Second Battle of Guararapes was the second and decisive battle in a conflict called the Pernambucana Insurrection, between Dutch and Portuguese forces in February 1649 at Jaboatão dos Guararapes in Pernambuco. The defeat convinced the Dutch "that the Portuguese were formidable opponents, something which they had hitherto refused to concede." With the defeats of the Dutch in the two battles, and the further setback of the Portuguese Recapture of Angola, which crippled the Dutch colony in Brazil as it couldn't survive without the slaves from Angola, opinion in Amsterdam considered that "Dutch Brazil by now no longer had a future worth fighting for," which "effectively sealed the fate of the colony." The Dutch still retained a presence in Brazil until 1654. The Treaty of The Hague was signed on 6 August 1661 between representatives of the Dutch Empire and the Portuguese Empire. Based on the terms of the treaty, the Dutch Republic recognized Portuguese imperial sovereignty over New Holland (Dutch Brazil) in exchange for an indemnity of 4 million reis over the span of 16 years.
