The First French Empire, officially the French Republic then the 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. Although France had already established a colonial empire overseas since the early 17th century, the French state had remained a kingdom under the Bourbons and a republic after the French Revolution. 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.

In the history of France, the First Republic, officially the French Republic, was founded on 22 September 1792 during the French Revolution. The First Republic lasted until the declaration of the First Empire in 1804 under Napoleon, although the form of the government changed several times. This period was characterized by the fall of the monarchy, the establishment of the National Convention and the Reign of Terror, the Thermidorian Reaction and the founding of the Directory, and, finally, the creation of the Consulate and Napoleon's rise to power.

The Army of Italy was a field army of the French Army stationed on the Italian border and used for operations in Italy itself. Though it existed in some form in the 16th century through to the present, it is best known for its role during the French Revolutionary Wars and Napoleonic Wars.

The Corps législatif was a part of the French legislature during the French Revolution and beyond. It is also the generic French term used to refer to any legislative body.

The French Republican calendar, also commonly called the French Revolutionary calendar, was a calendar created and implemented during the French Revolution, and used by the French government for about 12 years from late 1793 to 1805, and for 18 days by the Paris Commune in 1871. The revolutionary system was designed in part to remove all religious and royalist influences from the calendar, and was part of a larger attempt at decimalisation in France. It was used in government records in France and other areas under French rule, including Belgium, Luxembourg, and parts of the Netherlands, Germany, Switzerland, Malta, and Italy.

The French Revolutionary Wars were a series of sweeping military conflicts lasting from 1792 until 1802 and resulting from the French Revolution. They pitted France against Great Britain, the Holy Roman Empire, Prussia, Russia, and several other monarchies. They are divided in two periods: the War of the First Coalition (1792–97) and the War of the Second Coalition (1798–1802). Initially confined to Europe, the fighting gradually assumed a global dimension. After a decade of constant warfare and aggressive diplomacy, France had conquered a wide array of territories, from the Italian Peninsula and the Low Countries in Europe to the Louisiana Territory in North America. French success in these conflicts ensured the spread of revolutionary principles over much of Europe.

The Napoleonic Wars (1803–1815) were a series of major conflicts pitting the French Empire and its allies, led by Napoleon I, against a fluctuating array of European powers formed into various coalitions. It produced a brief period of French domination over most of continental Europe. The wars stemmed from the unresolved disputes associated with the French Revolution and its resultant conflict. The wars are often categorized into five conflicts, each termed after the coalition that fought Napoleon: the Third Coalition (1805), the Fourth (1806–07), the Fifth (1809), the Sixth (1813–14), and the Seventh (1815).

The Sénat conservateur was an advisory body established in France during the Consulate following the French Revolution. It was established in 1799 under the Constitution of the Year VIII following the Napoleon Bonaparte-led Coup of 18 Brumaire. It lasted until 1814 when Napoleon Bonaparte was overthrown and the Bourbon monarchy was restored. The Sénat was a key element in Napoleon's regime.
