François Bouchot in the context of "Coup d'état"

A coup d'état (/ˌkuːdeɪˈtɑː/ ; French: [ku deta] ; lit. 'stroke of state'), or simply a coup, is typically an illegal and overt attempt by a military organization or other government elites to unseat an incumbent person or leadership. A self-coup is said to take place when a leader, having come to power through legal means, tries to stay in power through illegal means.

By one estimate, there were 457 coup attempts from 1950 to 2010, half of which were successful. Most coup attempts occurred in the mid-1960s, but there were also large numbers of coup attempts in the mid-1970s and the early 1990s. Coups occurring in the post-Cold War period have been more likely to result in democratic systems than Cold War coups, though coups still mostly perpetuate authoritarianism.

The Treaty of Fontainebleau was an agreement concluded in Fontainebleau, France, on 11 April 1814 between Napoleon and representatives of Austria, Russia and Prussia. The treaty was signed in Paris on 11 April by the plenipotentiaries of both sides and ratified by Napoleon on 13 April. With this treaty, the allies ended Napoleon's rule as emperor of the French and sent him into exile on Elba.
