Scandinavian Unification
Following the threatening of North German Confederation invasion over Schlwesig-Holstein for Denmark, Sweden publically states that if Berlin invades they would face the might of Sweden's forces and call upon her allies to assist. King Christian, having just offered to join the North German Confederation in exchange for keeping Holstein, asks for and recieves aid from Sweden. In time the Norwegians find support of Denmark a common cause with Sweden and relations grow such that a common market forms in 1880, a common currency is enacted in 1890, and the path to gradual unification is established in 1900. Finland joins after seceding from Russia in 1918, as a reward for joining the Allies late in the war she recieves Tanzania and Togo which she begins to develop. Estonia and Latvia emerge as satellites who stay free of the Soviet grip by instead answering to Stockholm. By 1940 the Kingdom of Scandinavia emerges united stretching from Tallinn to Thule, and Germany courts Stockholm to no avail. Scandinavia is invaded by Germany early in the war but her strong Navy, supported by the British Royal Navy, prevents any landings across the Baltic or North Seas.
After the war Germany is forced to give up Weimar Mecklenburg province and westernmost Pommerania, which at first are very resistant to Scandinavian rule but gradually a plurality of Swedish-identity Germans emerges and even in 2020 both languages (along with English) are taught in Scandinavian Pommerania. Staying neutral in the Cold War makes Scandinavia a trade entrepot to both sides, one which ironically emerges with her own space program in the 1990s and becomes the 4th nation to place a person in orbit (2007) as well as the first module of a seven-module space station (2015). Plans for a lunar landing are in discussion and an extension of 'Olaf V Space Platform' is planned to include a pair of rooms specifically for space tourists.
