French Revolutionary Wars

The French Revolutionary Wars  were a series of sweeping military conflicts lasting from 1792 until 1802 and resulting from the French Revolution. They pitted France against Great Britain, the Holy Roman Empire, Prussia, Russia, and several other monarchies. They are divided in two periods: the War of the First Coalition (1792–97) and the War of the Second Coalition (1798–1802). Initially confined to Europe, the fighting gradually assumed a global dimension. After a decade of constant warfare and aggressive diplomacy, France had conquered a wide array of territories, from the Italian Peninsula and the Low Countries in Europe to the Louisiana Territory in North America. French success in these conflicts ensured the spread of revolutionary principles over much of Europe.
As early as 1791, the other monarchies of Europe looked with outrage at the revolution and its upheavals; and they considered whether they should intervene, either in support of King Louis XVI, to prevent the spread of revolution, or to take advantage of the chaos in France. Anticipating an attack, France declared war on Prussia and Austria in the spring of 1792 and they responded with a coordinated invasion that was eventually turned back at the Battle of Valmy in September. This victory emboldened the National Convention to abolish the monarchy.
