This paper deals with the approach of state power to public assemblies in interwar Czechoslovakia. It broaches the question of what the state-political authorities considered to be the limit of public order, which could not be crossed at political manifestations. Second, the paper focuses on the question of who determined the approach to public assemblies in the structure of the political administration. The issue is monitored within the manifestation culture of May Day. This holiday offers a defined field in which it is possible to study the ways in which the interwar state and its apparatus of political administration sought in practice the relationship between the guarantee of civil liberties (assembly or freedom of speech) and the protection of state authority.
