The Napoleonic era refers to the period in European history from 1799 to 1815, marked by the rise and fall of Napoleon Bonaparte. After the French Revolution, Napoleon became the leader of France and established a vast empire across Europe, implementing reforms in law, education, and governance through the Napoleonic Code. This era was characterized by a series of conflicts known as the Napoleonic Wars, where Napoleon sought to expand his influence. His campaigns reshaped European borders and led to significant political changes, ultimately culminating in his defeat at the Battle of Waterloo in 1815, which ended his rule and restored monarchies across Europe.
