The last two decades have witnessed an unprecedented expansion of knowledge about the transatlantic slave trade, both through research on specific sections of this traffic and through the consolidation of datasets into a single online resource: Voyages: The Transatlantic Slave Trade Database (hereafter Voyages Database). This collective project has elucidated in great detail the slave trading routes across the Atlantic and the broad African origins of captives, at least from their ports of embarkation. However, this multi-source database tells us little about the slave trading routes within the Americas, as slaves were shipped through various ports of disembarkation, sometimes by crossing imperial borders in the New World. This gap complicates our understanding of the slave trade to Spanish America, which depended on foreign slavers to acquire captives through a rigid system of contracts (asientos and licencias) overseen by the Crown up to 1789. These foreign merchants often shipped captives from their own American territories such as Jamaica, Curaçao, and Brazil. Thus, the slave trade connected the Spanish colonies with interlopers from England, France, the Netherlands, Portugal (within the Spanish domain from 1580 to 1640), and eventually the United States. The importance of the intra-American slave trade is particularly evident in Venezuela: while the Voyages Database shows only 11,500 enslaved Africans arriving in Venezuela directly from Africa, I estimate that 101,000 captives were disembarked there, mostly from other colonies. This article illuminates the volume of this traffic, the slave trading routes, and the origins of slaves arriving in Venezuela by exploring the connections of this Spanish colony with the Portuguese, Dutch, British, and French Atlantics. Imperial conflicts and commercial networks shaped the number and sources of slaves arriving in Venezuela. As supplies of captives passed from Portuguese to Dutch, and then to English hands, the colony absorbed captives from different African regions of embarkation.
