The Battle of Waterloo (18th June 1815), the defeat of Napoleon Bonaparte
The Napoleonic era, named after Napoleon Bonaparte.
For a period of 22 years, from 1793 to 1815 Britain waged war with France. There were two brief respites, in 1802-3 and 1814. What began as a war to check France’s avowed intention of carrying her revolutionary aims beyond her frontiers, had became, by 1800, a war to check the grandiose ambitions of her self-crowned Emperor, Napoleon I.
