The Napoleonic Wars (1803–1815) were a global series of conflicts fought by a fluctuating array of European coalitions against the French First Republic (1803–1804) under the First Consul followed by the First French Empire (1804–1815) under the Emperor of the French, Napoleon Bonaparte. The wars originated in political forces arising from the French Revolution (1789–1799) and from the French Revolutionary Wars (1792–1802) and produced a period of French domination over Continental Europe. The wars are categorised as seven conflicts, five named after the coalitions that fought Napoleon, plus two named for their respective theatres: the War of the Third Coalition, War of the Fourth Coalition, War of the Fifth Coalition, War of the Sixth Coalition, War of the Seventh Coalition, the Peninsular War, and the French invasion of Russia.

The French Empire, known retroactively as the First French Empire, was the empire ruled by Napoleon Bonaparte, who established French hegemony over much of continental Europe at the beginning of the 19th century. It lasted from 18 May 1804 to 6 April 1814 and again briefly from 20 March 1815 to 7 July 1815, when Napoleon was exiled to Saint Helena.

The ideas of the Age of Enlightenment came to Spain in the 18th century with the new Bourbon dynasty, following the death of the last Habsburg monarch, Charles II, in 1700. The period of reform and 'enlightened despotism' under the eighteenth-century Bourbons focused on centralizing the power of the Spanish government, and improvement of infrastructure, beginning with the rule of King Charles III and the work of his minister, José Moñino, count of Floridablanca. In the political and economic sphere, the crown implemented a series of changes, collectively known as the Bourbon reforms, which were aimed at making the overseas Spanish Empire more prosperous to the benefit of Spain.
