Napoleon rose to power in France after helping put down an uprising against the Directory. He gained popularity in the military for his tactics and victories over other European powers. However, his invasion of Russia in 1812 proved disastrous as his army was decimated by Russian retreat and winter. This defeat marked the beginning of the end for Napoleon. He was finally defeated at the Battle of Waterloo in 1815 and exiled to the remote island of St. Helena, where he died in 1821.
