Czech political parties - from cadre to mass parties

The presented text of this thesis focuses on the issue of changing the organizational structure of a party, or on the transition of one type of political party to another, ie from the side of the cadres to the side of the masses. The work is based primarily on the Duverger's classification of political parties, on the basis of which the criteria are based on which the parties are judged. These criteria are defined in the first part of the text. In the second part of the text, this typology is applied to selected political parties. Each of the monitored parties is examined separately according to the criteria presented and defined in the first part of the text. The research sample of this work is made up of the so-called "five" parties, ie Agrarians, Social Democrats, National Democrats, Christian Democrats and National Socialists. The thesis deals with the extent to which the designated political parties correspond to one or the other type and what changes their internal organization has experienced.
