(Note: The next paragraph was taken from Wikipedia, with small changes) The Hundred Days, sometimes known as the Hundred Days of Napoleon or Napoleon's Hundred Days for specificity, marked the period between Napoleon Bonaparte's return from exile on Elba to Paris on 20 March 1815 and the second restoration of King Louis XVIII on 8 July 1815. This period is also known as the War of the Seventh Coalition, and includes the Waterloo Campaign and the Neapolitan War.
