The Casa de Contratación (Spanish pronunciation: [ˈkasa ðe kontɾataˈθjon], "House of Trade") was established by the Crown of Castile, in 1503 in the port of Seville as a crown agency for the Spanish Empire. It functioned until 1790, when it was abolished in a government reorganization. Before the establishment of the Council of the Indies in 1524, the Casa de Contratación had broad powers over overseas matters, especially financial matters concerning trade and legal disputes arising from it. It also was responsible for the licensing of emigrants, training of pilots, creation of maps and charters, probate of estates of Spaniards dying overseas. Its official name was La Casa y Audiencia de Indias.
Unlike the later East India Companies, chartered companies established by the Dutch, English, and others, the Casa collected all colonial taxes and duties, approved all voyages of exploration and trade, maintained secret information on trade routes and new discoveries, licensed captains, and administered commercial law. In theory, no Spaniard could sail anywhere without the approval of the Casa. However, smuggling often took place in different parts of the vast Spanish Empire.
The Casa de Contratación was founded by Queen Isabella I of Castile in 1503, eleven years after the discovery of the Americas in 1492. The Casa was the Spanish counterpart of the Portuguese organization, the Casa da Índia, or House of Índia of Lisbon, established in 1434 and destroyed by the 1755 Lisbon earthquake.
Dr. Sancho de Matienzo became the first treasurer, Jimeno de Bribiesca the first contador, and Francisco Pinelo the first factor. They soon controlled the economic development of Hispaniola.
