The Napoleonic Wars (1803–1815) were a global series of conflicts fought by shared European coalitions against the French First Republic (1803–1804) under the First Consul followed by the First French Empire (1804–1815) under the Emperor of the French, Napoleon I. The wars originated in political forces arising from the French Revolution (1789–1799) and French Revolutionary Wars (1792–1802) and produced a period of French domination over continental Europe. The wars are categorised as seven conflicts, five named after the coalitions that fought Napoleon, plus two named for their respective theatres: the War of the Third Coalition, War of the Fourth Coalition, War of the Fifth Coalition, War of the Sixth Coalition, War of the Seventh Coalition, the Peninsular War, and the French invasion of Russia.
The first stage of the wars broke out when Britain declared war on France on 18 May 1803. After minor campaigns, Britain allied with Austria, Russia, and minor powers, to form the Third Coalition in April 1805. Napoleon defeated the allied Russo-Austrian armies in the subsequent war which climaxed in French victories at Ulm and at Austerlitz, leading to the absolute dissolution of the Holy Roman Empire and Austria being forced to make peace. Britain and Russia remained at war with France. Concerned about increasing French power, Prussia joined Britain and Russia in the Fourth Coalition, which resumed war in October 1806. Napoleon defeated the Prussians at Jena-Auerstedt and the Russians at Friedland, bringing an uneasy peace to the continent by July 1807, and again leaving Britain as France's sole major enemy. Britain was unable to dispute French dominance on the European continent but obtained hegemony over the seas after victories in places including Trafalgar. Russia used the interim peace to resolve wars with the Ottoman Turks, Swedes, and Iranians.
Hoping to isolate and weaken Britain economically through his Continental System, Napoleon launched an invasion of Portugal, the only remaining British ally in continental Europe. After occupying Lisbon in November 1807, and with the bulk of French troops present in Spain, Napoleon seized the opportunity to turn against his former ally, depose the reigning Spanish royal family, and declare his brother, Joseph I as the King of Spain in 1808, much to the disapproval of the Spanish populace. Spain joined Britain and Portugal, with the three powers engaging France in the Peninsular War. The diversion of French armies to the large new Anglo-Spanish front led to Austria reentering the conflict and forming the Fifth Coalition in April 1809, composed of Austria, Spain, and Britain. Austria won the Battle of Aspern–Essling but was defeated at Wagram, forcing the imposition of a harsh peace in October 1809. Britain, Spain, and Portugal remained at war with France.
Concurrently Russia, unwilling to bear the economic consequences of reduced trade, violated the Continental System, prompting Napoleon to launch an invasion in June 1812. The resulting campaign was costly for both sides, but ultimately ended in disaster for France and the near-destruction of Napoleon's Grande Armée. French forces retreated from Russia by December 1812 and began reconstituting their lost strength. Encouraged by the defeat, Austria, Prussia, and several minor powers joined Russia, Britain, and Spain in a Sixth Coalition and began a campaign against France. The Sixth Coalition defeated Napoleon at Leipzig in October 1813. The allies then invaded France on two fronts: the Russians, Austrians, and Prussians invaded France from the east, while the British, Spanish, and Portuguese invaded France from the west. Coalition troops captured Paris in March 1814, forced Napoleon to abdicate in April, exiled him to the island of Elba, and restored power to the Bourbons. Napoleon escaped exile in February 1815 and reassumed control of France for around one hundred days, igniting the eponymous conflict. The allies formed the Seventh Coalition, which defeated him at Waterloo in June 1815 and exiled him to the British island of Saint Helena, where he died in 1821.
The wars had profound consequences on history. New methods of warfare were introduced, including mass conscription and guerrilla warfare. Politically, the wars greatly influenced Europe through the advancements in civil law brought about by the Napoleonic Code, which was largely retained where it was adopted, and the spread of nationalism and liberalism. Independence movements emerged in Spanish America and Portuguese America in Latin America, as a direct consequence of the wars, leading to the massive decline of the Spanish Empire and Portuguese Empire. France's defeat led to the rise of Britain as the world's foremost naval and economic power, a status it would hold for the remainder of the century. After the end of the Napoleonic Wars, the Congress of Vienna redrew Europe's borders and brought a relative peace to the continent, with no major great power conflicts until the Crimean War in 1853.

British historians occasionally refer to the nearly continuous period of warfare from 1792 to 1815 as the Great French War, or as the final phase of the Anglo-French Second Hundred Years' War, spanning the period 1689 to 1815. Historian Mike Rapport (2013) suggested using the term "French Wars" to unambiguously describe the entire period from 1792 to 1815.
In France, the Napoleonic Wars are generally integrated with the French Revolutionary Wars: Les guerres de la Révolution et de l'Empire.
German historiography may count the War of the Second Coalition (1798/9–1801/2), during which Napoleon had seized power, as the Erster Napoleonischer Krieg ("First Napoleonic War").
In Dutch historiography, it is common to refer to the 7 major wars between 1792 and 1815 as the Coalition Wars (coalitieoorlogen), referring to the first two as the French Revolution Wars (Franse Revolutieoorlogen).
Napoleon's tactics
Napoleon was, and remains, famous for his battlefield victories, and historians have spent enormous attention in analysing them. In 2008, Donald Sutherland wrote:
The ideal Napoleonic battle was to manipulate the enemy into an unfavourable position through manoeuvre and deception, force him to commit his main forces and reserve to the main battle and then undertake an enveloping attack with uncommitted or reserve troops on the flank or rear. Such a surprise attack would either produce a devastating effect on morale or force him to weaken his main battle line. Either way, the enemy's own impulsiveness began the process by which even a smaller French army could defeat the enemy's forces one by one.
After 1807, Napoleon's creation of a highly mobile, well-armed artillery force gave artillery usage an increased tactical importance. Napoleon, rather than relying on infantry to wear away the enemy's defences, could now use massed artillery as a spearhead to pound a break in the enemy's line. Once that was achieved he sent in infantry and cavalry.
Prelude
Britain was irritated by several French actions following the Treaty of Amiens. Bonaparte annexed Piedmont and Elba, made himself President of the Italian Republic, a state in northern Italy that France had set up, and failed to evacuate Holland, as it had agreed to do in the treaty. France then continued to interfere with British trade despite peace having been made and complained about Britain harbouring certain individuals and not cracking down on the anti-French press.
Malta was captured by Britain during the war and was subject to a complex arrangement in the 10th article of the Treaty of Amiens, where it was to be restored to the Knights of St. John with a Neapolitan garrison and placed under the guarantee of third powers. The weakening of the Knights of St. John by the confiscation of their assets in France and Spain along with delays in obtaining guarantees prevented the British from evacuating it after three months as stipulated in the treaty.
The Helvetic Republic was set up by France when it invaded Switzerland in 1798. France had withdrawn its troops, but violent strife broke out against the government, which many Swiss saw as overly centralised. Bonaparte reoccupied the country in October 1802 and imposed a compromise settlement. This caused widespread outrage in Britain, which protested that this was a violation of the Treaty of Lunéville. Although continental powers were unprepared to act, the British decided to send an agent to help the Swiss obtain supplies, and also sent secret orders to the Cape Colony to prevent a Dutch takeover.
Swiss resistance collapsed before anything could be accomplished, and, after a month, Britain countermanded the orders to not restore Cape Colony. At the same time, Russia finally joined the guarantee regarding Malta. Concerned that there would be hostilities when Bonaparte found out that Cape Colony had been retained, the British began to procrastinate on the evacuation of Malta. In January 1803, a government paper in France published a report from a commercial agent which noted the ease with which Egypt could be conquered. The British seized on this to demand satisfaction and security before evacuating Malta, which was a convenient stepping stone to Egypt. France disclaimed any desire to seize Egypt and asked what sort of satisfaction was required, but the British were unable to give a response. There was still no thought of going to war; Prime Minister Henry Addington publicly affirmed that Britain was in a state of peace.
In early March 1803, the Addington ministry received word that Cape Colony had been reoccupied by the British army, in accordance with the orders which had subsequently been countermanded. On 8 March they ordered military preparations to guard against possible French retaliation and justified them by claiming that it was only in response to French preparations and that they were conducting serious negotiations with France. In a few days, it was known that Cape Colony had been handed over in accordance with the counter-orders, but it was too late. Bonaparte berated the British ambassador Lord Whitworth in front of 200 spectators over the military preparations.
The Addington ministry realised they would face an inquiry over their reasons for the military preparations, and during April unsuccessfully attempted to secure the support of William Pitt to shield them from damage. In the same month, the ministry issued an ultimatum to France, demanding a retention of Malta for at least ten years, the permanent acquisition of the island of Lampedusa from the Kingdom of Sicily, and the evacuation of Holland. They also offered to recognise French gains in Italy if they evacuated Switzerland and compensated the Kingdom of Sardinia for his territorial losses. France offered to place Malta in the hands of Russia to satisfy British concerns, pull out of Holland when Malta was evacuated, and form a convention to give satisfaction to Britain on other issues. The Addington ministry denied that Russia had made an offer, and Whitworth left Paris. Bonaparte sent a secret offer where he agreed to let Britain retain Malta if France could occupy the Otranto peninsula in Naples. Such efforts were futile, and Britain declared war on 18 May 1803.
War between Britain and France, 1803–1814
British motivations
Britain ended the uneasy truce created by the Treaty of Amiens when it had declared war on France in May 1803. The British were increasingly angered by Napoleon's reordering of the international system in Western Europe, especially in Switzerland, Germany, Italy and the Netherlands. Kagan argues that Britain was especially alarmed by Napoleon's assertion of control over Switzerland. The British felt insulted when Napoleon said they deserved no voice in European affairs (even though King George was an elector of the Holy Roman Empire) and sought to censor the London newspapers that were vilifying him.
Britain had a sense of loss of control, as well as loss of markets, and was worried by Napoleon's possible threat to its overseas colonies. McLynn argues that Britain went to war in 1803 out of a "mixture of economic motives and national neuroses—an irrational anxiety about Napoleon's motives and intentions." McLynn concludes that it proved to be the right choice for Britain because, in the long run, Napoleon's intentions were hostile to the British national interest. Napoleon was not ready for war, and so this was the best time for Britain to stop them. Britain seized upon the Malta issue, refusing to evacuate the island.
The deeper British grievance with Napoleon was his attempts to assume personal control of Europe, making the international system unstable, and forcing Britain to the sidelines. Numerous scholars have argued that Napoleon's aggressive posture made him enemies and cost him potential allies. As late as 1808, the continental powers affirmed most of his gains and titles, but the continuing conflict with Britain led him to start the Peninsular War and the invasion of Russia, which many scholars see as a dramatic miscalculation.
There was one serious attempt to negotiate peace with France during the war, made by Charles James Fox in 1806. The British offered to accept French conquests on the continent in exchange for France recognising British overseas conquests and restoring Hanover to George III. The French were willing to recognise Britain's control over Malta, the Cape Colony, Tobago, and French India but wanted to obtain Sicily in exchange for the restoration of Hanover, a condition which Fox's delegation refused.
