Abstract
In order to understand the position of all religions in the Czech Republic without distinction in size and time of arrival in the country or their founding in the territory of the Czech Republic, it should be emphasized that the forty-one year totalitarian regime led by the Communist Party of Czechoslovakia (1948-1989) significantly hindered the free competition between religion and secularism in the country. At that time all churches were attacked by the state suppressing power of the totalitarian regime aiming at their entire liquidation.
But the Marxism-Leninism might be also considered as a religion. Its "church" was the Communist party and submitted organizations such as the Union of the Youth, Unified Trade Unions, Union of Czechoslovak-Soviet Friendship and most of the cultural and sport organizations.
The exterior forms of Marxist-Leninist cult were the May Day Parades, all sport ceremonies (especially "Spartakiads"), celebrations of the Communist feasts (e.g. International Women's Day, Anniversaries of Soviet and Czechoslovak coups d'etats) and public activities of schools, factories, agricultural cooperatives and the army.
However, atheist or other similar organizations were suppressed.
