A great power is a nation or state that, through its great economic, political and military strength, is able to exert power and influence over not only its own region of the world, but beyond to others.
In a modern context, recognized great powers came about first in Europe during the post-Napoleonic era. The formalization of the division between small powers and great powers came about with the signing of the Treaty of Chaumont in 1814.
The historical terms "Great Nation", a distinguished aggregate of people inhabiting a particular country or territory, and "Great Empire", a considerable group of states or countries under a single supreme authority, are colloquial; their use is seen in ordinary historical conversations (historical jargon).
France was a dominant empire possessing many colonies in various locations around the world. The Empire of the French (1804–1814), also known as the Greater French Empire or First French Empire, but more commonly known as the Napoleonic Empire, was the empire of Napoleon I in France. It was the dominant power of much of continental Europe during the early 19th Century.
Napoleon became Emperor of the French (L'Empereur des Français) on 18 May 1804 and crowned Emperor 2 December 1804, ending the period of the French Consulate, and won early military victories in the War of the Third Coalition against Austria, Prussia, Russia, Portugal, and allied nations, notably at the Battle of Austerlitz (1805) and the Battle of Friedland (1807). The Treaty of Tilsit in July 1807 ended two years of bloodshed on the European continent. Subsequent years of military victories known collectively as the Napoleonic Wars extended French influence over much of Western Europe and into Poland. At its height in 1812, the French Empire had 130 départements, ruled over 50 million subjects, maintained extensive military presence in Germany, Italy, Spain, and the Duchy of Warsaw, and could count Prussia and Austria as nominal allies.
