West Germany

West Germany first formed in 1945 after WWll. It then merged with East Germany and Poland to form the German-Polish Empire(GPE). The Soviet Union attempted to stop this but then made a peace deal that stopped the bloodshed and left the GPE to do whatever they want. Several years later and the empire has expanded a lot but West Germany started wanting independence not liking the imperialism so it funded rebels everywhere from Switzerland to Tsingtao. After East Germany found out, they worked out a deal that gave West Germany independence in exchange for Military access, free travel between the nations, and East Germany being able to move all their equipment out. After a bit, the Germanies realized they needed to fix borders so they did that. West Germany would then go onto researching Electric Guitar improvements, military stuff, and space tech.
