The Republic of Russia, Russian Republic, or Russia is a massive nation located in eastern Europe, northern Asia, and northwestern North America. The republic was founded in 1922 after the overthrow of the Russian Empire. The Soviet Union was established then, and later replaced (in name only) by the Russian Republic in 1924 when Vladimir Lenin died and Leon Trotsky replaced him. Trotsky modernized the nation, instituted vast democratization measures, and contributed to the spread of communism across the globe through the Russian Revolutionary Wars.
In a series of conflicts from 1935 to 1949, Russia invaded over 15 countries and spread communism as far into Europe as Spain. Other communist revolutions attributed to the Revolutionary Wars include China, Italy, Germany, and Turkey, although these were not always immediately successful. Russia played a key role in the liberalization of Europe, was an important player in the World War, and was the main reason national socialism did not succeed in seizing power in the rest of the world.
