A series of negotiations named The Peace of Utrecht took place here between 1713 and 1715. These ended the succession war of the Spanish throne between France, Spain, Great-Britain and the Dutch Republic, who all had legal claim to the throne. An important part of the negotiations was the assigning of the Asiento de Negros. This contract gave companies the exclusive right to sell enslaved people to the Spanish crown in their South American colonies. The asiento also legitimized slave trade in international law. The Dutch WIC had the Asiento between 1685 and 1688 with Great Britain gaining the contract during The Peace of Utrecht, which made them an even more dominant international power. It is important to note that the WIC still sold enslaved people to the Spanish crown when the actual contract holder could not keep up with the market demand for enslaved labour.
