Napoleon Bonaparte (born Napoleone Buonaparte;[a] 15 August 1769 – 5 May 1821), later known by his regnal name Napoleon I, was a Corsican-born French military commander and political leader who rose to prominence during the French Revolution and led successful campaigns during the Revolutionary Wars. He was the de facto leader of the French Republic as First Consul from 1799 to 1804, then Emperor of the French from 1804 until 1814 and again in 1815. Napoleon's political and cultural legacy endures to this day, as a highly celebrated and controversial leader. He initiated many liberal reforms that have persisted in society, and is considered one of the greatest military commanders in history. His campaigns are still studied at military academies worldwide. Between three and six million civilians and soldiers died in what became known as the Napoleonic Wars.[2][3]
