Final answer:
Napoleon was defeated by a coalition and exiled to Elba in 1814, returned during the Hundred Days, but was ultimately defeated again at Waterloo in 1815 and exiled to Saint Helena.
Step-by-step explanation:
Napoleon Bonaparte faced a significant defeat in 1814 at the hands of a European coalition which led to his abdication and exile to the island of Elba. Despite escaping from Elba and temporarily regaining power, his ultimate defeat came at the Battle of Waterloo in 1815 at the hands of British and Prussian forces. Following this loss, Napoleon was exiled for a second time to a much more remote island, Saint Helena, in the South Atlantic, where he would spend the remainder of his life.
After the Battle of Leipzig in 1813, where the French army was significantly outnumbered and subsequently pursued to Paris, Napoleon’s popularity in France waned. In 1814, under the Treaty of Fontainebleau, he was forced to abdicate and was exiled to Elba. However, dissatisfaction with the restored Bourbon monarchy led to Napoleon's return in 1815, known as the Hundred Days, which concluded with his defeat at Waterloo and final exile to Saint Helena.
