North Germany was a state within the Unified World during the Cold War. With Russia liberating north Germany and the Western allies liberating Austria and southern Germany, Germany was divided. Attempts at unification failed, resulting in the establishment of North Germany and South Germany.
Control was handed over to Unitarian politicians in 1949, but Russian forces remained stationed in the nation. The nation's economy was centrally planned and state-owned, and North Germany underwent a period of Russianization, resulting in underground German nationalist movements forming. In 1993, North Germany was formally added to the growing Unitarian nation of Russia. These nationalist groups surfaced, and launched protests and eventually violent, guerrilla campaigns.
10 years later, with Russia facing collapsing, the nationalist groups took control of North Germany and announced their wish to reunite with their southern counterpart. The two nations were finally reunited on August 13, 2003.
