Following the Russian Revolution of 1917, socialism and communism gained prominence as ideologies in Europe. The upheaval in Russia demonstrated the potential for a working-class uprising against capitalist structures and inspired revolutionary movements across the continent. The establishment of the Soviet Union as the first socialist state led to the spread of Marxist ideas, challenging the established capitalist systems in various countries. Political parties advocating for socialism gained traction, leading to significant social and political movements, including the rise of labor movements and leftist politics. The success of the Bolsheviks significantly influenced the political landscape in Europe for much of the 20th century.
