small and scattered, and so expeditions continued periodically into the interior. During this time the vast majority of the enslaved Africans who were brought to Pernambuco were from Portuguese Angola, perhaps as many as 90%, and therefore it is no surprise that tradition, reported as early as 1671 related that its first founders were Angolan. This large number was primarily because the Portuguese used the colony of Angola as a major raiding base, and there was a close relationship between the holders of the contract of Angola, the governors of Angola, and the governors of Pernambuco. In 1630 the Dutch West India Company sent a fleet to conquer Pernambuco, in the context of the Dutch-Portuguese War, during the period of the Iberian Union. Although they captured and held the city of Recife, they were unable (and generally unwilling) to conquer the rest of the province. As a result, there was a constant low-intensity war between Dutch and Portuguese settlers. During this time thousands of enslaved people escaped and went to the Palmares. Although initially the Dutch considered making an alliance with Palmares against the Portuguese, peace agreements put them in the position of supporting the sugar plantation economy of Pernambuco. Consequently, the Dutch leader John Maurice of Nassau decided to send expeditions against Palmares. These expeditions also collected intelligence about them, and it is from these accounts that we learn about the organization of Palmares in their time. By the 1640s, many of the mocambos had consolidated into larger entities ruled by kings. Dutch descriptions by Caspar Barlaeus (published 1647) and Johan Nieuhof (published 1682) spoke of two larger consolidated entities, "Great Palmares" and "Little Palmares". In each of these units there was a large central town that was fortified and held 5,000-6,000 people. The surrounding hills and valleys were filled with many more mocambos of 50 to 100 people. A description of the visit of Johan Blaer to one of the larger mocambos in 1645 (which had been abandoned) revealed that there were 220 buildings in the community, a church, four smithies, and a council house. Churches were common in Palmares partly because Angolans were frequently Christianized, either from the Portuguese colony or from the Kingdom of Kongo, which was a Christianized country at that time. Others had been converted to Christianity while enslaved. According to the Dutch, they used a local person who knew something of the church
