Napoleonic Wars, series of wars fought between France and a number of European nations from 1799 to 1815. In 1799 France came under the domination of Napoleon Bonaparte, who later became Napoleon I, emperor of France, in 1804. The Napoleonic Wars were a continuation of the wars of the French Revolution (1789-1799), in which the Habsburgs and other dynastic rulers of Europe combined in an effort to overthrow the revolutionary government of France and restore the rule of the French monarchy.
