Final answer:
Napoleon Bonaparte met his final defeat at the Battle of Waterloo in 1815 after escaping exile from Elba and briefly regaining power in France. His second abdication followed, leading to his exile on St. Helena, where he died in 1821.
Step-by-step explanation:
Napoleon Bonaparte, a significant historical figure, experienced a turning point in his military career at the Battle of Waterloo in 1815. After his abdication in 1814 and subsequent exile to Elba, Napoleon made a daring escape and regained control of France. His efforts to further expand his empire were met with resolute opposition by European powers, leading to his final defeat at Waterloo.
Despite early successes in the battle, the Prussian army's arrival sealed Napoleon's fate and led to his second abdication and exile to St. Helena. This remote South Atlantic island would be his last residence, where he spent his remaining years until his death in 1821. His ambition to rule Europe ultimately failed, leaving a legacy that continues to be studied by historians today.
