The Napoleonic Wars (1803–1815) were a series of conflicts fought between the First French Empire under Napoleon (1804–1815) and a fluctuating array of European coalitions. 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 First French Empire, officially the French Republic, then the French Empire after 1809 and also known as Napoleonic France, 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 3 May 1814 and again briefly from 20 March 1815 to 7 July 1815, when Napoleon was exiled to St. Helena.
