Dictionary of the Napoleonic Wars

"The Napoleonic Wars (1803?1815) were a series of wars declared against Napoleon's French Empire by opposing coalitions. As a continuation of the wars sparked by the French Revolution of 1789, they revolutionised European armies and played out on an unprecedented scale, mainly owing to the application of modern mass conscription. French power rose quickly as Napoleon's armies conquered much of Europe but collapsed rapidly after France's disastrous invasion of Russia in 1812. Napoleon's empire ultimately suffered complete military defeat resulting in the restoration of the Bourbon monarchy in France and the creation of the Concert of Europe."--Wikipedia.
