Title: Spain and the American Revolutionary War
Content:  The reforms made by Spanish authorities as a result of Spain's poor performance in the Seven Years' War had proved generally successful. As a result, Spain retained Menorca and West Florida in the Treaty of Paris and also regained East Florida. The lands east of the Mississippi, however, were recognized as part of the newly independent United States of America.
Title: Action of 14 September 1779
Content:  In the aftermath of the Seven Years' War, Spain was forced to cede Florida and Menorca in the Treaty of Paris to the British, gaining back Havana and Manila in return. The war marked a humiliating downfall from the height of Spanish military ascendancy during the War of the Austrian Succession, and forced the King of Spain Charles III to undergo a military review of his armed forces. This resulted in a massive reorganization of the Spanish military from the top down. Spain entered the American Revolutionary War on the side of the Americans, eager to avenge their earlier defeat, and laid siege to Gibraltar along with dispatching expeditions to re-capture Florida and

Content:  United Kingdom was the best policy for Spain, the American Revolutionary War was too great an opportunity for Charles III to pass up, and Spain went to war against Britain alongside France and the Dutch Republic in 1779, after providing monetary assistance to the rebels. Bernardo de Gálvez, the governor of Spanish Louisiana, led the campaign to retake the forts lost to the British since 1762; Pensacola, Florida was retaken in 1782, and the Bahamas were seized later that year. The Treaty of Paris (1783) restored much of what Spain had lost in the Seven Years' War, including Florida.

Spain entered the war after the Battle of Saratoga, with the aim, as in the Seven Years' War, of recovering Gibraltar and Menorca and removing the British presence near New Spain. Their successful invasion of Menorca in 1781, and the capture of West Florida and East Florida from the British, showed a renewed strength in the New World, although the British defence of Gibraltar prevented the Spanish achieving all their war goals.

Spain regained Florida with the Treaty of Paris (1783), which ended the American Revolutionary War (1775–83), and gained an improved international standing. However, there were no reforming impulses in the reign of Charles IV (1788 to abdication in 1808), seen by some as mentally handicapped. Dominated by his wife's lover, Manuel de Godoy, Charles IV embarked on policies that overturned much of Charles III's reforms. After briefly opposing Revolutionary France early in the French Revolutionary Wars, Spain was cajoled into an uneasy 
Title: Spain and the American Revolutionary War
Content:  Spain's involvement in the American Revolutionary War was widely regarded as a successful one. The Spanish took a gamble in entering the war, banking on Great Britain's vulnerability caused by the effort of fighting their rebellious colonists in North America while also conducting a global war on many fronts against a coalition of major powers. This helped Spain gain some relatively easy conquests.  The war gave a boost to the kingdom's prestige, which had suffered from the losses to Britain in the Seven Years' War. Even though Spain's single most coveted target, Gibraltar, remained out of its grasp, Spain had more than compensated by recovering Menorca and by reducing

Content:  Spain was forced to return to Portugal the small cities of Almeida and Chaves on the Hispano-Portuguese frontier. All the other cities and strongholds had been retaken by the Anglo-Portuguese army during the chase of the remnants of the Franco-Spanish troops.

Content: Although she was attracted by the prospect of a war [against England] for restitution and revenge, she was repelled by the specter of an independent and powerful American republic. Such a new state might reach over the Alleghenies into the Mississippi Valley and grasp territory that Spain wanted for herself. Even worse, it might eventually seize Spain's colonies in the New World. The involvement of France was decisive in the British defeat. Spain's contribution was important too. By allying themselves with foreign monarchies, the United States took advantage of the power struggles within European imperialism and essentially formed a united front against Britain. The new nation was eager to spread republicanism, which could threaten Spain's own colonies, and later did so, in the Latin American wars of independence. Nevertheless, Spain maintained a level of support throughout the war in pursuit of its geopolitical interests. Historian Thomas A. Bailey says of Spain:

In most parts of Spanish America during the Napoleonic period in Spain, wars of independence broke out, so that by the time Bourbon Ferdinand VII was restored to the throne in 1814, much of Spanish America had achieved independence and established constitutional republics. New Spain (Mexico) and Peru were the exceptions, becoming independent in 1821 (Mexico) and 1824 (Peru). Mexico briefly had a monarchy under royalist military officer turned insurgent Agustín de Iturbide, who was overthrown in favor of a federated republic under the Constitution of 1824.
Title: History of Spain
Content:  Spain lost all of its North and South American territories, except Cuba and Puerto Rico, in a complex series of revolts 1808–26. Spain was at war with Britain 1798–1808, and the British Navy cut off its ties to the overseas empire. Trade was handled by American and Dutch traders. The colonies thus had achieved economic independence from Spain, and set up temporary governments or juntas which were generally out of touch with the mother country. After 1814, as Napoleon was defeated and Ferdinand VII was back on the throne, the king sent armies to regain control and reimpose autocratic rule. In the next phase 1809–16, Spain defeated all the uprising. A second round 1816–25 was successful and drove the Spanish out of all of its mainland holdings. Spain had no
