Final answer:
Rosa Luxemburg had a differing opinion on Lenin's revolutionary socialism, criticizing his tactics and the establishment of a dictatorship instead of a socialist society.
Step-by-step explanation:
Rosa Luxemburg had a differing opinion on Lenin's revolutionary socialism. She held the belief that the Bolsheviks, led by Lenin, were establishing a dictatorship rather than a socialist society. Luxemburg criticized Lenin's tactics and criticized the Bolshevik Party for suppressing political opponents and limiting democratic freedoms. She argued that this approach would not lead to the liberation of the proletariat. Luxemburg believed in a more democratic and decentralized socialism, where power was distributed among the workers and the people.
