First French Empire

The French Empire (French: Empire français; Latin: Imperium Francicum), 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.

Historians refer to Napoleon's regime as the "First Empire" to distinguish it from the restorationist Second Empire (1852–1870) ruled by his nephew Napoleon III. Neither should be confused with the French colonial empire, which refers to France's various colonies, protectorates and mandate territories all throughout its history, regardless of political system (including, by some definitions, some or all of France's current overseas territories).

On 18 May 1804 (28 Floréal year XII on the French Republican calendar), Napoleon was granted the title Emperor of the French (Empereur des Français, pronounced [ɑ̃pʁœʁ de fʁɑ̃sɛ]) by the French Sénat conservateur and was crowned on 2 December 1804 (11 Frimaire year XIII), signifying the end of the French Consulate and of the French First Republic. Despite his coronation, the state continued to be formally called the "French Republic" until October 1808. The empire achieved military supremacy in mainland Europe through the War of the Third Coalition, where French armies scored a string of decisive victories against Austrian and Russian forces, most notably at the Battle of Austerlitz in 1805. French dominance was reaffirmed during the War of the Fourth Coalition, at the Battle of Jena–Auerstedt in 1806 and the Battle of Friedland in 1807, before Napoleon's final defeat at the Battle of Waterloo in 1815.

A series of wars, known collectively as the Napoleonic Wars, extended French influence to much of Western Europe and into Poland. At its height in 1812, the French Empire had 130 departments, a population over 44 million people, ruled over 90 million subjects throughout Europe, maintained an extensive military presence in Germany, Italy, Spain, and Poland, and counted Austria and Prussia as nominal allies. Early French victories exported many ideological features of the Revolution throughout Europe: the introduction of the Napoleonic Code throughout the continent increased legal equality, established jury systems and legalised divorce, and seigneurial dues and seigneurial justice were abolished, as were aristocratic privileges in all places except Poland. France's defeat in 1814 (and then again in 1815), marked the end of the First French Empire and the beginning of the Bourbon Restoration.

In 1799, Napoleon Bonaparte was confronted by Emmanuel Joseph Sieyès—one of five Directors constituting the executive branch of the French government—who sought his support for a coup d'état to overthrow the Constitution of the Year III. The plot included Bonaparte's brother Lucien, then serving as speaker of the Council of Five Hundred, Roger Ducos, another Director, and Charles Maurice de Talleyrand. On 9 November 1799 (18 Brumaire VIII under the French Republican Calendar) and the following day, troops led by Napoleon Bonaparte seized control. They dispersed the legislative councils, leaving a rump legislature to name Bonaparte, Sieyès, and Ducos as provisional Consuls to administer the government. Although Sieyès expected to dominate the new regime, the Consulate, he was outmaneuvered by Bonaparte, who drafted the Constitution of the Year VIII and secured his own election as First Consul. He thus became the most powerful person in France, a power that was increased by the Constitution of the Year X, which made him First Consul for life.

The Battle of Marengo (14 June 1800) inaugurated the political idea that was to continue its development until Napoleon's Russian campaign. The Peace of Amiens, which cost him control of Egypt, was a temporary truce. He gradually extended his authority in Italy by annexing the Piedmont and by acquiring Genoa, Parma, Tuscany, and Naples, and added this Italian territory to the Cisalpine Republic. Then he laid siege to the Roman state and initiated the Concordat of 1801 to control the material claims of the Pope. When he recognised his error of raising the authority of the Pope from that of a figurehead, Napoleon produced the Articles Organiques (1802) with the goal of becoming the legal protector of the papacy, like Charlemagne. To conceal his plans before their actual execution, he aroused French colonial aspirations and the memory of the 1763 Treaty of Paris, worsening British relations with France, whose borders now extended to the Rhine and beyond, to Hanover, Hamburg, and Cuxhaven. Napoleon would have ruling elites from a fusion of the new bourgeoisie and the old aristocracy.

On 12 May 1802, the French Tribunat voted unanimously, with the exception of Lazare Carnot, in favour of the Life Consulship for the leader of France. This action was confirmed by the Corps Législatif. A general plebiscite followed thereafter resulting in 3,653,600 votes aye and 8,272 votes nay. On 2 August 1802 (14 Thermidor, An X), Napoleon Bonaparte was proclaimed Consul for life. Pro-revolutionary sentiment swept through Germany aided by the "Recess of 1803", which brought Bavaria, Württemberg, and Baden to France's side. Prime Minister William Pitt the Younger, back in power in Britain, appealed once more for an Anglo-Austro-Russian coalition against France to counter French expansionism.

On 18 May 1804, Napoleon was given the title of "Emperor of the French" by the Senate; finally, on 2 December 1804, he was solemnly crowned, after receiving the Iron Crown of the Lombard kings, and was consecrated by Pope Pius VII in Notre-Dame de Paris. In four campaigns, the Emperor transformed his "Carolingian" feudal republican and federal empire into one modelled on the Roman Empire. The memories of imperial Rome were for a third time, after Julius Caesar and Charlemagne, used to modify the historical evolution of France. Though the vague plan for an invasion of Great Britain was never executed, the Ulm campaign and the Battle of Austerlitz overshadowed the defeat at Trafalgar, and the camp of Boulogne put at Napoleon's disposal the best military resources he had commanded, in the form of La Grande Armée.
