Communism and fascism are two forms of totalitarianism
true
false

1.Communism is a socio economic system that stands for a class less, state less and an egalitarian society. Fascism is an ideology that tries to bring together radical and authoritarian nationalism.
2.Fascism became popular between 1919 and 1945. Communism became popular after the Bolshevik Revolution of Russia in 1917.
3.The Communist Manifesto by Karl Marx and Friedrich Engels is considered to be the bible of communism. The authoritative document of Fascism is “The Doctrine of Fascism.
4. Communism stands for a stateless society where all are equal. Fascism pertains to state and it considers state on top of everything

Actually, they are very close together in meaning except that fascism has more nationalism in it.
