The Council of the Indies; officially, the Royal and Supreme Council of the Indies (Spanish: Real y Supremo Consejo de Indias, pronounced: [reˈal i suˈpɾemo konˈsexo ðe ˈindjas]), was the most important administrative organ of the Spanish Empire for the Americas and the Philippines. The crown held absolute power over the Indies and the Council of the Indies was the administrative and advisory body for those overseas realms. It was established in 1524 by Charles V of Spain to administer "the Indies," Spain's name for its territories. Such an administrative entity, on the conciliar model of the Council of Castile, was created following the Spanish conquest of the Aztec empire in 1521, which demonstrated the importance of the Americas. It start as a section under the jurisdiction of the Council of Castile, but was then established as an autonomous body with legislative, executive and judicial functions. The Council of the Indies was abolished in 1812 by the Cádiz Cortes, briefly restored in 1814 by Ferdinand VII of Spain, and definitively abolished in 1834 by the regency, acting on behalf of the four-year-old Isabella II of Spain.
Queen Isabella had granted extensive authority to Christopher Columbus, but then withdrew that authority, and established direct royal control, putting matters of the Indies in the hands of her chaplain, Juan Rodríguez de Fonseca in 1493. The Catholic Monarchs (Isabella and Ferdinand) designated Rodríguez de Fonseca to study the problems related to the colonization process arising from what was seen as tyrannical behavior of Governor Christopher Columbus and his misgovernment of Natives and Iberian settlers. Rodríguez de Fonseca effectively became minister for the Indies and laid the foundations for the creation of a colonial bureaucracy. He presided over a committee or council, which contained a number of members of the Council of Castile (Consejo de Castilla), and formed a Junta de Indias of about eight counselors. Emperor Charles V was already using the term "Council of the Indies" in 1519. The Council of the Indies was formally created on August 1, 1524. The king was informed weekly, and sometimes daily, of decisions reached by the Council, which came to exercise supreme authority over the Indies at the local level and over the Casa de Contratación ("House of Trade") founded in 1503 at Seville as a customs storehouse for the Indies. Civil suits of sufficient importance could be appealed from an audiencia in the New World to the Council, functioning as a court of last resort.
