The birth of the French Communist Party began the decline of the Bourse du Travail movement. The CGT, which had regrouped the individual organisations, was swept up in the ideological tumult of the post war years. It became, like much of the French left, dominated by the Communists ideological vision, which saw the loose federalism of Revolutionary Syndicalism as a reason for the failure of the 1918-1919 strike wave. In 1921, the CGT revised its structure, eliminating the local Bourses du Travail as constituent organisation of the Union, and replacing them with a network of "Unions Locales". From here on, the CGT followed a British and American model of local trade specific unions, federated into a single national structure.
