Napoleonic Wars: The Conflicts That Shaped Modern Europe

An overview of the Napoleonic Wars (1803-1815), a series of conflicts that reshaped Europe's political map and introduced new forms of warfare.
What is it?
The Napoleonic Wars were a series of major global conflicts fought from 1803 to 1815, pitting the French Empire and its allies, led by Napoleon Bonaparte, against a fluctuating array of European coalitions. A continuation of the French Revolutionary Wars, these conflicts saw French power rise to dominate most of continental Europe. The wars are generally considered to have begun in May 1803 when Britain declared war on France, ending a brief period of peace. Key battles include Austerlitz, Trafalgar, and the disastrous French invasion of Russia in 1812. The wars concluded with Napoleon's final defeat at the Battle of Waterloo in June 1815 and the signing of the Second Treaty of Paris.
Why is it trending?
The Napoleonic Wars remain a subject of interest due to their profound and lasting impact on global history. The conflicts were instrumental in the spread of ideals from the French Revolution, such as nationalism and liberalism. They led to the dissolution of the Holy Roman Empire and the reorganization of German and Italian territories, which set the stage for their eventual unification. The legal reforms of the Napoleonic Code also left an enduring legacy in many countries. Furthermore, the wars solidified Britain's position as the world's foremost naval and economic power and triggered independence movements in Latin America by weakening Spain and Portugal.
How does it affect people?
The Napoleonic Wars brought about radical changes in European society. The application of mass conscription dramatically increased the scale of warfare, leading to widespread devastation and significant loss of life. For many, French occupation introduced liberal reforms like due process in courts, the abolition of serfdom, and reduced the power of the church. Economically, the wars were disruptive; Napoleon's Continental System, an embargo against British trade, strained many European economies. In the long term, the rise of nationalism reshaped European identity, moving from allegiance to monarchs and fiefdoms to ideologies based on shared culture and origins. The period of relative peace that followed, established by the Congress of Vienna, also enabled significant migration to the United States.
