One of the first contacts between France and Sweden was in 799 during the first Viking raids of the Frankish northern coast. In March 845 Viking Danish-Swedish King Ragnar brought 120 ships up the Seine river for the Siege of Paris. The Vikings left Paris after a month of battle when Frankish King Charles the Bald paid them 7,000 lbs of silver and gold. In 911 after multiple Viking invasions, Frankish King Charles the Simple conceded the town of Saint-Clair-sur-Epte to the Vikings. In 1499, France and Sweden signed a Trade Treaty for which Sweden sent France hides, skins, furs, butter, fish oil, herrings, whales, tar, timber for the navy, iron and copper. In exchange, the French sent salt Brouage, wheat, wine, canvas, sheets, silks and spices. In 1631, during the Thirty Years' War, France and Sweden signed the Treaty of Bärwalde which obliged Sweden to maintain an army of 36,000 troops, and France to fund the Swedish army annually with 400,000 Reichsthalers. In the 1700s, French culture and the French language became a big influence on the Swedish monarchy. Swedish king Gustave III received a French education as a child. Several prominent Swedish nobles studied in France. Influenced by the French Academy of Sciences, Sweden created the Royal Swedish Academy of Sciences.
In 1805, Sweden entered into the War of the Third Coalition and fought against France in the Franco-Swedish War in an effort to defeat France under Napoleon Bonaparte. The war lasted until January 1810 when Sweden was defeated by France's ally at the time, Russia. After the war, France and Sweden signed the Treaty of Paris. That same year after the war, French MarshalJean-Baptiste Jules Bernadotte who served under Emperor Napoleon; was elected as the heir-presumptive to King Charles XIII of Sweden who was childless. Bernadotte was elected partly because a large part of the Swedish Army, in view of future complications with Russia, were in favor of electing a soldier, and because he was also popular with the Swedish army, owing to the kindness he had shown to the Swedish prisoners in Lübeck. Bernadotte accepted the offer. In 1813, Bernadotte successfully led Swedish troops against Napoleon during the War of the Sixth Coalition which resulted in Napoleon being exiled to the Island of Elba in 1814. In 1818 Bernadotte was crowned King of Sweden and King of Norwayafter defeating Norway in the war of 1814 after demanded Denmark to cede Norway to Sweden after the Napoleonic Wars as compensation for the loss of Finland in the Finnish War's to which the allies agreed, mainly to prevent further conflict. The Danish king ceded Norway shortly after the demands in fear of Sweden declaring war on Denmark. After the defeat of Norway in 1814 the creation of the union between Sweden and Norway came through. The union lasted for almost a century until being peacefully dissolved in 1905. After this he became Charles XIV John of Sweden, and simultaneously founded the House of Bernadotte from which the current Swedish royal family hails from. Sweden declared itself officially neutral in 1818 from future conflicts.
World Wars
During World War I and World War II Sweden remained officially neutral during both conflicts, however, unofficially sympathized more with the allies and provided military training to allied soldiers. During World War II, French born Swedish diplomat Raoul Nordling secretly met with German General Dietrich von Choltitz to try to limit the bloodshed and damage to the city of Paris during the Liberation of Paris.
Post World Wars
Since the end of the world wars, both France and Sweden have joined the European Union. Both nations have had numerous high-level visits and cooperate jointly in several multilateral organizations. There are approximately 15,000 Swedish nationals living in France and 3,500 French nationals living in Sweden.
Military cooperation
Military cooperation between France and Sweden is modest as the Swedish focus on exchanges with their Nordic neighbors. Cooperation is primarily operational and has, during the Libyan crisis, enabled Swedish Gripen fighters to take part in NATO air operations. The Swedish armed forces have cooperated with French forces in Africa on several occasions, particularly during the Operation Artemis, UNIFIL Maritime Task Force, and EUFORChad.
Trade
In 2015, trade between France and Sweden totaled €10 billion Euros. In 2014, Sweden was France's 16th-largest customer and 18th-largest supplier. At the same time, France was Sweden’s 8th-largest customer and 9th-largest supplier. French foreign direct investment in Sweden totalled €3.3 billion in 2013, primarily in the agrifood, equipment and electrical goods sectors. Swedish FDI in France totalled €5.2 billion in 2013, particularly in the automobile industry. Swedish companies such as IKEA and Volvo operate in France.
