In July 1453, a French army crushed its English opponents at the Battle of Castillon
, the last major engagement of the Hundred Years War
. The decisive victory at Castillon showcased the power of artillery against charging masses of infantry and allowed the French to capture Bordeaux
a few months later. The English subsequently lost their major remaining possessions on the European continent.
The military history of France encompasses an immense panorama of conflicts and struggles extending for more than 2,000 years across areas including modern France, Europe, and a variety of regions throughout the world.
According to historian Niall Ferguson: "of the 125 major European wars fought since 1495, the French have participated in 50 – more than Austria (47) and England (43). Out of 168 battles fought since 387 BC, they have won 109, lost 49 and drawn 10."
The first major recorded wars in the territory of modern-day France itself revolved around the Gallo-Roman conflict that predominated from 60 BC to 50 BC. The Romans eventually emerged victorious through the campaigns of Julius Caesar. After the decline of the Roman Empire, a Germanic tribe known as the Franks took control of Gaul by defeating competing tribes. The "land of Francia", from which France gets its name, had high points of expansion under kings Clovis I and Charlemagne, who established the nucleus of the future French state. In the Middle Ages, rivalries with England prompted major conflicts such as the Norman Conquest and the Hundred Years' War. With an increasingly centralized monarchy, the first standing army since Roman times, and the use of artillery, France expelled the English from its territory and came out of the Middle Ages as the most powerful nation in Europe, only to lose that status to the Holy Roman Empire and Spain following defeat in the Italian Wars. The Wars of Religion crippled France in the late 16th century, but a major victory over Spain in the Thirty Years' War made France the most powerful nation on the continent once more. In parallel, France developed its first colonial empire in Asia, Africa, and in the Americas. Under Louis XIV France achieved military supremacy over its rivals, but escalating conflicts against increasingly powerful enemy coalitions checked French ambitions and left the kingdom bankrupt at the opening of the 18th century.
Resurgent French armies secured victories in dynastic conflicts against the Spanish, Polish, and Austrian crowns. At the same time, France was fending off attacks on its colonies. As the 18th century advanced, global competition with Great Britain led to the Seven Years' War, where France lost its North American holdings. Consolation came in the form of dominance in Europe and the American Revolutionary War, where extensive French aid in the form of money and arms, and the direct participation of its army and navy led to America's independence. Internal political upheaval eventually led to 23 years of nearly continuous conflict in the French Revolutionary Wars and the Napoleonic Wars. France reached the zenith of its power during this period, dominating the European continent in an unprecedented fashion under Napoleon Bonaparte. By 1815, however, it had been restored to the same borders it controlled before the Revolution. The rest of the 19th century witnessed the growth of the Second French colonial empire as well as French interventions in Belgium, Spain, and Mexico. Other major wars were fought against Russia in the Crimea, Austria in Italy, and Prussia within France itself.
Following defeat in the Franco-Prussian War, Franco–German rivalry erupted again in the First World War. France and its allies were victorious this time. Social, political, and economic upheaval in the wake of the conflict led to the Second World War, in which the Allies were defeated in the Battle of France and the French government signed an armistice with Germany. The Allies, including the Free French Forces led by a government in exile, eventually emerged victorious over the Axis Powers. As a result, France secured an occupation zone in Germany and a permanent seat on the United Nations Security Council. The imperative of avoiding a third Franco-German conflict on the scale of the first two world wars paved the way for European integration starting in the 1950s. France became a nuclear power and, since the late 20th century, has cooperated closely with NATO and its European partners.
