Left communists claim that the "communist" or "socialist" states or "people's states" were actually state capitalist and thus cannot be called "socialist". Some of the earliest critics of Leninism were the German-Dutch left communists, including Herman Gorter, Anton Pannekoek and Paul Mattick. Though most left communists see the October Revolution positively, their analysis concludes that by the time of the Kronstadt revolt the revolution had degenerated due to various historical factors. Rosa Luxemburg was another communist who disagreed with Lenin's organizational methods which eventually led to the creation of the Soviet Union.
