Democratic Centralism is the name given to the principles of internal organization used by Leninist political parties.

The democratic aspect of this organizational method describes the freedom of members of the political party to discuss and debate matters of policy and direction, but once the decision of the party is made by majority vote, all members are expected to uphold that decision. This latter aspect represents the centralism.

As Lenin described it, democratic centralism consists of “Freedom of discussion, Unity of action.”
