The Treaty of Kiel was signed on January 14, 1814, between the Kingdom of Denmark and the United Kingdom, along with Sweden. This treaty marked the end of the conflict between Denmark and the allies during the Napoleonic Wars. As a result, Denmark ceded the territories of Norway to Sweden and the Duchy of Holstein to the Duchy of Schleswig. The treaty significantly altered the political landscape in Northern Europe. It aimed to stabilize the region after years of warfare and shifting alliances. The transfer of Norway to Sweden was particularly notable, as it established a new union that lasted until 1905.
