The Hundred Days was the time of the re-rule of the French Emperor Napoleon Bonaparte in France between March 20 and June 22, 1815. It began with his escape from exile on the island of Elba.
An anti-French coalition was formed against Napoleon with the participation of many European countries. After a series of battles in this last military campaign of the Napoleonic Wars with varying success, Napoleon's army was finally defeated in the general battle of Waterloo on June 18, 1815.
On June 22, 1815 Napoleon Bonaparte, under pressure from circumstances, abdicated again and went into forced exile on the island of Saint Helena, in English captivity and far from the worldly vanity of Europe.
During the Hundred Days, the Congress of Vienna did not interrupt its meetings to restore the previous status quo and the restoration in France after the French Revolution.
