Bolshevism is the practices (and to a lesser extent the theory) of the Bolshevik party and its leaders Lenin and Stalin and key figures such as Trotsky who claimed to follow in its footsteps. It has particular conceptions of the party as a vanguard distinct and distinguished from rest of the working class. It also has concepts of organising using democratic centralism. Most modern Bolshevik parties claim to try and emulate the practices of the original. Multiple tendencies including within Marxism reject Bolshevism as a model or the only model to follow.
