Louisiana (New Spain) in the context of "Gilbert Antoine de St. Maxent"

New Spain, officially the Viceroyalty of New Spain (Spanish: Virreinato de Nueva España [birejˈnato ðe ˈnweβa esˈpaɲa] ; Nahuatl: Yankwik Kaxtillan Birreiyotl), originally the Kingdom of New Spain, was an integral territorial entity of the Spanish Empire, established by Habsburg Spain. It was one of several domains established during the Spanish conquest of the Americas, and had its capital in Mexico City. Its jurisdiction comprised a large area of the southern and western portions of North America, mainly what became Mexico and the Southwestern United States, but also California, Florida and Louisiana; Central America (as part of Mexico); the Caribbean like Hispaniola and Martinique, and northern parts of South America, even Colombia; several Pacific archipelagos, including the Philippines and Guam. Additional Asian colonies included "Spanish Formosa", on the island of Taiwan.

After the 1521 Spanish conquest of the Aztec Empire, conqueror Hernán Cortés named the territory New Spain, and established the new capital, Mexico City, on the site of Tenochtitlan, the capital of the Aztec Empire. Central Mexico became the base of expeditions of exploration and conquest, expanding the territory claimed by the Spanish Empire. With the political and economic importance of the conquest, the crown asserted direct control over the densely populated realm. The crown established New Spain as a viceroyalty in 1535, appointing as viceroy Antonio de Mendoza, an aristocrat loyal to the monarch rather than the conqueror Cortés. New Spain was the first of the viceroyalties that Spain created, the second being Peru in 1542, following the Spanish conquest of the Inca Empire. Both New Spain and Peru had dense indigenous populations at conquest as a source of labor and material wealth in the form of vast silver deposits, discovered and exploited beginning in the mid-1600s.

Pierre Laclède Liguest or Pierre Laclède (22 November 1729 – 20 June 1778) was a French fur trader who, with his young assistant and stepson Auguste Chouteau, founded St. Louis in 1764, in what was then Spanish Upper Louisiana, in present-day Missouri.

The Louisiana Purchase (French: Vente de la Louisiane, lit. 'Sale of Louisiana') was the acquisition of the territory of Louisiana by the United States from the French First Republic in 1803. This consisted of most of the land in the Mississippi River's drainage basin west of the river. In return for fifteen million dollars, or approximately eighteen dollars per square mile ($7/km), the United States nominally acquired a total of 828,000 sq mi (2,140,000 km; 530,000,000 acres) now in the Central United States. However, France only controlled a small fraction of this area, most of which was inhabited by Native Americans; effectively, for the majority of the area, the United States bought the preemptive right to obtain Indian lands by treaty or by conquest, to the exclusion of other colonial powers.

The Kingdom of France had controlled the Louisiana territory from 1682 until it was ceded to Spain in 1762. In 1800, Napoleon Bonaparte, the First Consul of the French Republic, regained ownership of Louisiana in exchange for territories in Tuscany as part of a broader effort to re-establish a French colonial empire in North America. However, France's failure to suppress a revolt in Saint-Domingue in the Caribbean, coupled with the prospect of renewed warfare with the United Kingdom, prompted Napoleon to consider selling Louisiana to the United States.

The Third Treaty of San Ildefonso was a secret agreement signed on 1 October 1800 between Spain and the French Republic by which Spain agreed in principle to exchange its North American colony of Louisiana for territories in Tuscany. The terms were later confirmed by the March 1801 Treaty of Aranjuez.

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).

The Florida Parishes, on the east side of the Mississippi River—an area also known as the Northshore or Northlake region—are eight parishes in the southeastern portion of the U.S. state of Louisiana.

The Florida Parishes were part of what was known as West Florida in the 18th and early 19th centuries. Unlike most of the state, this region was not part of the 1803 Louisiana Purchase, which applied to territory west of the Mississippi River. First settled by the French, it was ceded to Great Britain in 1763 after France's defeat in the Seven Years' War. The British exchanged it with Spain following the American Revolutionary War for territory outside North America. This area was acquired by the U.S. in 1812 and combined with the new state of Louisiana.

The Rebellion of 1768, also known as the Revolt of 1768 or the Creole Revolt, was an unsuccessful attempt by the Louisiana French Creole elite of New Orleans, along with nearby German settlers, to reverse the transfer of the French Louisiana to Spain, as had been stipulated in the 1762 Treaty of Fontainebleau.

The rebellion forced the Spanish Governor, Antonio de Ulloa, to leave New Orleans and return to Spain, but his replacement, General Alejandro O'Reilly, was able to crush the rebellion, execute five of its ringleaders, and firmly establish Spanish control over the territory.
