The objective of the submitted study is to give an analytical assessment of the causes of KSČ’s strong support in interwar Prague, as indicated by the extremely positive electoral results achieved by the party during the 1920s and 1930s. Our focus is the roots of the preparedness of historical players for political activism and active, often violent, appearances at demonstrations and political rallies. Using social and cultural history methods, the study reconstructs the mobilisation mechanisms built up by party organisations which allowed the communist movement to maintain a stable membership base together with an extensive network of sympathisers and their subsequent use in attempts at destabilising the prevailing social order.
