"The Napoleonic wars pitted France, led by Napoleon Bonaparte, against a number of countries in Europe from 1797 through 1815. At different times during this period, Great Britain, Austria, Russia, Prussia, Denmark, Sweden, and the Neapolitan Kingdom all waged war against France in various coalitions.
