Sweden (Swedish: Sverige [ˈsværjɛ]), officially the Kingdom of Sweden (Swedish: Konungariket Sverige), is a Scandinavian country in Northern Europe. Sweden borders Norway and Finland, and is connected to Denmark by a bridge-tunnel across the Øresund.
At 450,295 square kilometres (173,860 sq mi), Sweden is the third largest country in the European Union by area, with a total population of about 9.5 million as of 2010. Sweden's capital city is Stockholm, which is also the largest city.
Prior to the Thirty Years' War, Sweden was a re-made into a strong Protestant nation by the ascension of King Gustavus Adolphus of Sweden, who had modernized Sweden's military. Sweden entered into the European conflict: in the support of the German Lutherans; to forestall Catholic aggression against Sweden, and; to obtain economic influence in the German states around the Baltic Sea. In addition, Gustavus was concerned about the growing power of the Holy Roman Empire.
Following the arrival of the American town of Grantville, Sweden became instrumental in forming the Confederated Principalities of Europe and later its successor, the United States of Europe. (While Sweden and the CPoE/USE were linked through Gustavus' dual roles as King and Emperor, Sweden was not part of the CPoE or USE.)
The country engaged the newly established League of Ostend and was successful in defeating one of its member nations and Scandinavian rival, Denmark, which Sweden absorbed into the historical Union of Kalmar.
By 1635, the economical problems of Sweden have been solved as the technologies and resources from the USE have turned Sweden into one of the richest countries in Europe.
