The Captaincy General of Cuba (Spanish: Capitanía General de Cuba) was an administrative district of the Spanish Empire created in 1607 as part of Habsburg Spain attempt to better defend and administer its Caribbean possessions. The reform also established captaincies general in Puerto Rico, Guatemala and Yucatán.
The restructuring of the Captaincy General in 1764 was the first example of the Bourbon Reforms in America. The changes included adding the provinces of Florida and Louisiana and granting more autonomy to these provinces. This later change was carried out by the Count of Floridablanca under Charles III to strengthen the Spanish position vis-a-vis the British in the Caribbean. A new governor-captain general based in Havana oversaw the administration of the new district. The local governors of the larger Captaincy General had previously been overseen in political and military matters by the president of the Audiencia of Santo Domingo. This audiencia retained oversight of judicial affairs until the establishment of new audiencias in Puerto Príncipe (1800) and Havana (1838).
In 1825, as a result of the loss of the mainland possessions, the Spanish government granted the governors-captain generals of Cuba extraordinary powers in matters of administration, justice and the treasury and in the second half of the 19th century gave them the title of Governor General.
Since the 16th century the island of Cuba had been under the control of the governor-captain general of Santo Domingo, who was at the same time, president of the audiencia there. He oversaw the local governor and the Santo Domingo Audiencia heard appeals from the island.
The conquest of Cuba was organized in 1510 by the recently restored Viceroy of the Indies, Diego Colón, under the command of Diego Velázquez de Cuéllar, who became Cuba's first governor until his death in 1524. The new settlers did not wish to be under the personal authority of Colón, so Velázquez founded the city of Nuestra Señora de la Asunción de Baracoa in 1511 and convoked a general cabildo (a local government council), which was duly authorized to deal directly with Spain. This legal move removed Velázquez and the settlers from under the authority of Colón, their nominal superior. It was a precedent that would come back to haunt Velázquez during Hernán Cortés's conquest of the Aztec Empire. Other cities were later founded under Velázquez: Bayamo in 1513; Santísima Trinidad, Sancti Spíritus and San Cristóbal de La Habana in 1514; Puerto Príncipe and Santiago de Cuba in 1515. After the Spanish conquest of the Aztec Empire, Cuba experienced an exodus of settlers, and its population remained small for the next two centuries.
In 1565 the Adelantado Pedro Menéndez de Avilés, who was also Captain General of the Spanish treasure fleet which rendezvoused in Havana, established the first permanent Spanish settlement in Florida,
