The Province of Yucatán (/ˌjuːkəˈtɑːn, -ˈtæn/ YOO-kə-TA(H)N, UK also /ˌjʊk-/ YUU-; Spanish: Provincia de Yucatán [pɾoˈβinsja ðe ʝukaˈtan]), or the Captaincy General, Governorate, Intendancy, or Kingdom of Yucatán, was a first order administrative subdivision of the Viceroyalty of New Spain in the Yucatán Peninsula.
Mexico has experienced many changes in territorial organization during its history as an independent state. The territorial boundaries of Mexico were affected by presidential and imperial decrees. One such decree was the Law of Bases for the Convocation of the Constituent Congress to the Constitutive Act of the Mexican Federation, which determined the national land area as the result of integration of the jurisdictions that corresponded to New Spain, the Captaincy General of Yucatán, the Captaincy General of Guatemala and the autonomous Kingdoms of East and West. The decree resulted in the independence from Spain.
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's 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).
