Swetania (/ˈswiːtænɪə/), officially the Panswetanian Council Republic, is a sovereign state in Northern Euclea. It borders, clockwise, Werania, Estmere, Hennehouwe, Kesselbourg, Gaullica, Aimilia, Minerva, Kansasto, and the Perovo Sea. Swetania has an area of 459,800 km² (177,500 sq mi) and a population of nearly 53 million inhabitants scattered, between the country's thirty-one cantons. Its capital is the planned and centrally located Swetapolis, while its largest city is the coastal metropolis of Ostapils-Baihaven. With over twenty officially recognised nationalities, Swetania is commonly recognised as Euclea's most ethnically and linguistically diverse country.
Swetania has its origins in the establishment of the margraviate of Sunrosia in 1015, a southern march of the Ahnemunde Confederation that later developed into a duchy and grand duchy. Through the inheritance of the Crown of Visvaldis and the election to the fragmented Principality of Trevelia, Sunrosia became the heart of the composite Sunrosian Monarchy. Despite being the primary battlefield of the Wars of Religion, Swetania grew to dominate Northern Euclea in the Sunrosian Ascendancy of the long 18th century, until its defeat in the War of the Triple Alliance. In its aftermath, the Adalbertine Monarchy was established and presided over a period of modernisation, with rapid industrialisation and liberalisation.
Following defeats in the Airdale War, in a context of worsening conditions caused by the Great Collapse, a general strike was proclaimed, and after the Leneys Street Incident in November evolved into the Winter Revolution. The Panswetanian Council Republic was declared in January, though counter-revolutionary insurgencies and warlordism would continue until the country's entry in the Great War in 1931, commonly recognised to have turned the tide of the war for the Grand Alliance. Following the war, the Swetanian policy of exporting its ideology led to its involvement in multiple countries over the world, and tense relations with Werania evolved into a cold war, including the Red Rebellion in Estmere and the Swetanian-Weranian War in 1950.
Today, Swetania is a constitutionally socialist council republic, in which the General Congress, made up of delegate from lower level councils down to the communal levels, enjoys legislative supremacy as the supreme representative organ of the people. The 12-members Presidium of the General Congress serves as the collective head of state and of government of the country. Swetania's high-income, socialist economy is characterised by workers' self-management, forms of collective ownership, and economic planning through the computerised Gebesis information network. A highly developed country with a very high standard of living, it upholds the world's most extensive social security system with universal healthcare, tuition-free education, and environmental protection.
As the world's leading socialist country, Swetania is widely recognised as a great power. It is a founding member of the Community of Nations, the premier backer of the International Congress, a member of the International Council for Democracy, one of the six CoN-mandated nuclear weapon states, and a major backer of the Spalgleann Declarations.
