From the same TL as that Russian Alaska scenario I did a while back. The Soviet Union(Советский Союз,
Sovetsky Soyuz), officially known as the Union of Soviet Socialist Republics(Союз Советских Социалистических Республик,
Soyuz Sovetskikh Sotsialisticheskikh Respublik) and sometimes colloquially known as Russia(Россия,
Rossiya) or the USSR(СССР,
SSSR), is a large transcontinental country in northern Eurasia. Officially a federation of constituent republics, in practice power is heavily centralized. The Soviet Union came into being following the October Revolution brought about by the Russian Empire’s defeat in the Great War. The Treaty of Brest-Litovsk signed with the German Empire led to the independence of Poland, Ukraine, Belarus, Lithuania, Finland, and the United Baltic Duchy while Russia collapsed into civil war between the communist Bolsheviks led by Vladimir Lenin and the anti-communist White Army.
The Russian Civil War would end with the Bolsheviks taking power over continental Russia while the Whites retreated to Alaska. Lenin would not like long after his victory, however, dying in 1924 and being succeeded by a certain Leon Trotsky. Trotsky’s two main rivals, Nikolai Bukharin and Joseph Stalin, would both be arrested, with Stalin dying in prison. In 1937, Trotsky’s USSR launched a surprise invasion of the Hetmanate of Ukraine and the Kingdom of Belarus, launching the German-Soviet War. While the Soviets enjoyed initial successes under the generals Tukhachevsky and Zhukov, they would eventually be beaten back by the 1939 German counteroffensive. As the Soviets began to endure heavier losses, Trotsky was voted out of office by the Soviet Politburo in 1942 and his old rival Nikolai Bukharin was released from prison to take the reigns of power.
Bukharin made peace with the Germans on January 7th, 1943, returning all land taken from the German Empire and its allies(except for the warm water port of Crimea). Bukharin’s government then set about transitioning the Soviet economy away from the inefficient central planning which had dominated, though still paying lip service to the doctrines of Marx and Lenin. Having failed to militarily defeat the capitalist powers, Bukharin decided that instead, the Soviet Union would economically outcompete them. Bukharin died in 1954, but succeeding governments continued his policies. Today, the Soviet Union is the world’s second largest economy, behind the United States and ahead of the Republic of China. Since 1992, the Soviet Union has been led by Gennady Zyuganov. Controversially, Zyuganov’s government has overseen a rehabilitation of Leon Trotsky’s image and increasing belligerence with the west, particularly over the status of Alaska.
