Sweden’s involvement in the Napoleonic Wars (1803–1815) played a critical role in shaping its modern history, especially its shift towards neutrality and its eventual union with Norway. During this period, Sweden navigated shifting alliances, faced territorial losses, and ultimately redefined its place in European politics.
Background
At the turn of the 19th century, Sweden was still recovering from the disastrous Great Northern War (1700–1721), which had weakened its status as a great power. The country was ruled by Gustav IV Adolf, a staunch opponent of revolutionary France and Napoleon. His reign would see Sweden become embroiled in the broader European conflict that was sparked by Napoleon's rise to power.
Initial Alliances and the War Against France
Sweden’s early involvement in the Napoleonic Wars was marked by its adherence to anti-French coalitions. Gustav IV Adolf fiercely opposed Napoleon and aligned Sweden with Great Britain and Russia, who were both major players in the coalition forces against Napoleonic France. Sweden remained part of the Third and Fourth Coalitions during the early phases of the war, though its military engagements were limited.
In 1805, Sweden joined the Third Coalition but failed to play a significant military role. The country’s participation mostly involved naval cooperation with Britain and limited skirmishes in northern Germany.
The Loss of Finland (1808–1809)
One of the most critical consequences of Sweden’s involvement in the Napoleonic Wars was the Finnish War (1808–1809), a separate conflict with Russia, an ally of Napoleon at the time. Russia, aiming to secure its northern flank, invaded Finland, which had been under Swedish control for centuries. Despite Swedish resistance, Russia quickly overran Finland, and Sweden was forced to sign the Treaty of Fredrikshamn in 1809, ceding Finland to Russia.
Aftermath of the Finnish War. Geopsis
The loss of Finland, which had been an integral part of Sweden, was a major blow and a national humiliation. This defeat led to widespread dissatisfaction with King Gustav IV Adolf, whose rigid and unsuccessful foreign policy was blamed for the disaster.
Deposition of Gustav IV Adolf and a New Constitution (1809)
In the aftermath of the Finnish War, Gustav IV Adolf was overthrown in a coup d'état in 1809, and a new constitution was established that limited the powers of the monarchy. Charles XIII, the aging uncle of Gustav IV Adolf, was installed as king, though he had no heirs. Sweden sought stability and a new path forward, with its place in European politics in question.
Alliance with France and the Rise of Bernadotte (1810)
Facing political instability and territorial loss, Sweden needed new leadership. In a surprising turn of events, Jean-Baptiste Bernadotte, a French marshal and one of Napoleon’s trusted commanders, was elected Crown Prince of Sweden in 1810, as Charles XIII's heir. Bernadotte adopted the name Charles John (Karl Johan) and quickly gained influence in Sweden.
Bernadotte's appointment marked a major shift in Sweden's foreign policy. Though originally from Napoleon’s circle, Bernadotte soon distanced himself from the French emperor. He sought to balance Sweden's interests by allying with Britain and Russia, Napoleon's enemies, in order to secure Swedish ambitions in the region.
War Against Denmark-Norway and the Congress of Vienna
Under Bernadotte’s leadership, Sweden entered into a strategic alliance with Britain and Russia, and in 1813, Sweden joined the Sixth Coalition against Napoleon. Bernadotte led Swedish forces in northern Germany, participating in key battles such as the Battle of Leipzig (1813), which contributed to Napoleon’s defeat.
Bernadotte’s primary goal, however, was not to defeat Napoleon, but to secure Norway for Sweden. As Denmark-Norway was allied with Napoleon, Sweden used this as an opportunity to claim Norwegian territory. In 1814, after Napoleon’s defeat, the Treaty of Kiel forced Denmark to cede Norway to Sweden in exchange for keeping its colonies. This led to the creation of the Swedish-Norwegian Union, which lasted until 1905.
Sweden’s Role in the Congress of Vienna
Following Napoleon's defeat, Sweden participated in the Congress of Vienna (1814–1815), which redrew the map of Europe after the Napoleonic Wars. Sweden, under Bernadotte, was recognized as a key player in the new European order, securing the union with Norway and maintaining its territorial integrity. This marked the end of Sweden's role as a military power, as the country began to adopt a policy of non-intervention and neutrality in European conflicts, a stance that would shape its modern identity.
Aftermath and Legacy
- The Napoleonic Wars fundamentally reshaped Sweden’s political and territorial landscape:
- Loss of Finland: The cession of Finland to Russia was a defining moment in Swedish history, marking the end of centuries of Swedish influence in the eastern Baltic.
- Swedish-Norwegian Union: The acquisition of Norway compensated for the loss of Finland and formed a new political union that lasted until the early 20th century.
- End of Swedish Great Power Status: The wars confirmed Sweden's transition from a major European military power to a smaller, neutral nation focused on stability and non-intervention.
Under Bernadotte, who eventually became King Charles XIV John of Sweden, the country entered a long period of peace and internal development. Sweden’s involvement in the Napoleonic Wars marked the last major military engagement for the country, and the beginning of its modern identity as a peaceful, neutral state.
