colonial Mexico The 18th century saw the Bourbons on the Spanish throne engage in a series of global conflicts that pitted primarily France against Britain. Spain, as an ally of France, was drawn into these conflicts. In fact part of the motivation for the Bourbon Reforms was the perceived need to prepare the empire administratively, economically, and militarily for what was the next expected war. The
Seven Years' War proved to be catalyst for most of the reforms in the overseas possessions, just like the
War of the Spanish Succession had been for the reforms on the Peninsula. In 1720, the
Villasur expedition from
Santa Fe met and attempted to parley with
French- allied
Pawnee in what is now
Nebraska. Negotiations were unsuccessful, and a battle ensued; the Spanish were badly defeated, with only 13 soldiers managing to return to New Mexico. Although this was a small engagement, it is significant in that it was the deepest penetration of the Spanish into the
Great Plains, establishing the limit to Spanish expansion and influence there. The
War of Jenkins' Ear broke out in 1739 between Spain and Britain and was confined to the Americas. The major action in the War of Jenkins' Ear was a major
amphibious attack launched by British forces under Admiral
Edward Vernon in March 1741 against
Cartagena de Indias, one of Spain's major gold-trading ports in the Caribbean (today
Colombia). Vernon's forces made some initial headway against the Spanish defenders but became bogged down and started suffering tremendous casualties to yellow fever. Vernon eventually made the decision to withdraw from Cartagena de Indias after thousands of his troops had died from yellow fever. During the
Seven Years' War, British forces invaded and captured the cities of
Havana,
Cuba and
Manila, Philippines in 1762. The 1763
Treaty of Paris gave Spain control over the
Louisiana part of
New France including
New Orleans, creating a Spanish empire that stretched from the
Mississippi River to the Pacific Ocean; Spain also ceded
Florida to Great Britain in order to regain Cuba, which the British occupied during the war. Louisiana settlers, hoping to restore the territory to France, in the bloodless
Rebellion of 1768 forced the
Louisiana Governor Antonio de Ulloa to flee to Spain. The rebellion was crushed in 1769 by the next governor
Alejandro O'Reilly, who executed five of the conspirators. The Louisiana territory was to be administered by superiors in Cuba with a governor on site in New Orleans. The 21 northern
missions in present-day California (U.S.) were established along California's
El Camino Real from 1769. In an effort to exclude Britain and Russia from the eastern Pacific, King
Charles III of Spain sent forth from Mexico a number of
expeditions to the Pacific Northwest between 1774 and 1793. Spain's long-held claims and navigation rights were strengthened and a settlement and fort were built in
Nootka Sound, Alaska. and his army at the
Siege of Pensacola in 1781 Spain entered the
American Revolutionary War as an ally of the United States and France in June 1779. From September 1779 to May 1781,
Bernardo de Galvez led an army in a campaign along the
Gulf Coast against the British forces there. Galvez's army consisted of Spanish regulars from throughout Latin America and a militia which consisted of mostly
Acadians along with Creoles, Germans, and Native Americans. Galvez's army slowly pushed the British out of the region,
capturing Fort Bute,
Baton Rouge,
Fort Rosalie,
Fort Charlotte and
Pensacola. The loss of these forts and settlements left the British with no bases along the Gulf Coast. In 1782, forces under Galvez's overall command
captured Nassau in
the Bahamas. Galvez was angry that the operation had proceeded against his orders to cancel, and ordered the arrest and imprisonment of
Francisco de Miranda,
aide-de-camp of
Juan Manuel Cajigal, the commander of the expedition. Miranda later ascribed this action on the part of Galvez to jealousy of Cajigal's success. In the second
Treaty of Paris, which ended the American Revolutionary War, Great Britain returned control of Florida back to Spain in exchange for the Bahamas. Spain then had control over the Mississippi River south of 32°30' north latitude, and, in what is known as the Spanish Conspiracy, hoped to gain greater control of Louisiana and all of the west. These hopes ended when Spain was pressured into signing
Pinckney's Treaty in 1795. France re-acquired Louisiana from Spain in the secret
Treaty of San Ildefonso in 1800. The United States bought the territory from France in the
Louisiana Purchase of 1803. New Spain claimed the entire west coast of North America and therefore considered the Russian fur trading activity in Alaska, which began in the middle to late 18th century, an encroachment and threat. Likewise, the exploration of the northwest coast by Captain
James Cook of the
Royal Navy and subsequent fur trading activities by British merchants was viewed by Spain as an encroachment on Spanish territory. To protect and strengthen its claim, New Spain sent a number of
expeditions to the Pacific Northwest between 1774 and 1793. In 1789, a naval outpost called
Santa Cruz de Nuca (or just Nuca) was established at
Friendly Cove in
Nootka Sound (now Yuquot),
Vancouver Island. It was protected by an
artillery land battery called
Fort San Miguel. Santa Cruz de Nuca was the northernmost establishment of New Spain. It was the first European colony in what is now the province of
British Columbia and the only Spanish settlement in what is now
Canada. Santa Cruz de Nuca remained under the control of New Spain until 1795, when it was abandoned under the terms of the third
Nootka Convention. Another outpost, intended to replace Santa Cruz de Nuca, was partially built at
Neah Bay on the southern side of the
Strait of Juan de Fuca in what is now the
U.S. state of
Washington. Neah Bay was known as
Bahía de Núñez Gaona in New Spain, and the outpost there was referred to as "Fuca." It was abandoned, partially finished, in 1792. Its personnel, livestock, cannons, and ammunition were transferred to Nuca. In 1789, at Santa Cruz de Nuca, Spanish naval officer
Esteban José Martínez detained the British merchant
James Colnett, triggering the
Nootka Crisis, which grew into an
international incident that threatened to lead to an outbreak of war between Britain and Spain. The first
Nootka Convention averted the war but left many specific issues unresolved. Both sides sought to define a northern boundary for New Spain. At Nootka Sound, the diplomatic representative of New Spain,
Juan Francisco de la Bodega y Quadra, proposed a boundary at the Strait of Juan de Fuca, but the British representative,
George Vancouver refused to accept any boundary north of
San Francisco. No agreement could be reached and the northern boundary of New Spain remained unspecified until the
Adams–Onís Treaty with the United States (1819). That treaty also ceded
Spanish Florida to the United States. == End of the Viceroyalty (1806–1821) ==
