Napoleon was a French military leader who rose to power during the French Revolution and who, in 1804, transformed the French First Republic into the First French Empire, five years after his coup d'état of November 1799. Napoleon and the Grande Armée had to fight against every major European power and dominated continental Europe through a series of military victories during the Napoleonic Wars. He installed members of his family on the thrones of client states, expanding the power of the dynasty.
