What was the first country to adopt socialist principles?
History of socialism
The initial success of the Russian Revolution inspired other revolutionary parties to attempt the same thing unleashing the Revolutions of 1917-23. In the chaotic circumstances of postwar Europe, with the socialist parties divided and discredited, Communist revolutions across Europe seemed a possibility. Communist parties were formed, often from minority or majority factions in most of the world's socialist parties, which broke away in support of the Leninist model.
