Answer:
Karl Marx and Friedrich Engels together published 'The Communist Manifesto' in 1848 to introduce their idea of socialism. They offered a critique of capitalism as it divides the society into Bourgeoisie and Proletarian. The conditions of capitalism become the key cause of class struggle and compel the Proletarians to fight for their rights and bring revolution to displace the capitalistic oppression. Thus, he urges for a communist society where no classes exist and every individual is equal.
