What was the effect of the Napoleonic Wars? They caused destruction in Europe but made France a united nation. They made France the strongest and most popular country in the world.

the Napoleonic Wars were caused by the French Revolution. After years of excesses caused by the French Revolution, Napoleon rose to establish some measure of peace and stability in France. The Wars of the Revolution were still raging however and its hard to tell if Napoleon originally intended all of Europe to fall under his sway, or if that came later. Anyway, in trying to secure his and France's position and later expand his position he ultimately came to fight all of the great powers in Europe.

Explanation:

The Napoleonic Wars went from 1792 to 1815, as seven coalitions were formed against France during those years, each including the United Kingdom. During the wars of the French Revolution, France defeated the First Coalition, then, under the Consulate of Napoleon Bonaparte, it defeated the Second Coalition. After becoming Emperor, Napoleon defeated Austria and Russia during the Third Coalition; Prussia and Russia during the Fourth Coalition; and Austria alone during the Fifth Coalition. But while the Great Army triumphed in central Europe, it got bogged down in a long war of occupation in Spain, and England dominated the seas from the Battle of Trafalgar. After the failure of an attempted invasion of Russia by France, the Sixth Coalition was victorious in Leipzig and overthrew Napoleon in 1814. The following year, the returning Emperor was definitively defeated by the Seventh Coalition in Waterloo.

These wars revolutionized the European armies and in particular the use of artillery, as well as all the military organization, on a scale never seen before, mainly due to the modern introduction of the mass conscription. France, on the momentum of revolutionary conquests, saw its power grow rapidly and extended its domination to the entire continent. The fall was even faster, from the disastrous retreat from Russia to the Battle of Waterloo, until the Bourbon dynasty was provisionally restored in France. All of these conflicts resulted in a total of 3.5 million to 6.5 million deaths.
