The Manifesto of the Seven (Czech: Manifest sedmi) was a protest by seven artists against the Bolshevization of the Communist Party of Czechoslovakia (KSČ), after its 5th Congress in 1929.
In 1925, the party decided to carry out a process of Bolshevization, it wanted to leave the course that had been relatively libertarian up to that point and to instead adopt the politics of the Comintern.
[3] In this manifesto they expressed their fear that the planned strict orientation towards Moscow would jeopardize the party's mass character to date and, as a result, its ability to act in favor of a “faction hazard”; this is, according to the manifesto, "a suicidal policy" based on the mistakes of one's own comrades.
Zásadní stanovisko k projevu sedmi (Basic Declaration on the Manifesto of Seven) was signed by Karel Teige, Konstantin Biebl, Vítězslav Nezval, Vilém Závada, František Halas, Karel Konrád, Jiří Weil, Julius Fučík, Bedřich Václavek, Vladimír Clementis, Laco Novomeský and Vojtech Tittelbach.
[6] However, Konstantin Biebl and Vilém Závada were signed in this document without their own knowledge,[3] and some of them (like Clementis and Novomeský) fell victim to a Stalinist purge, after the establishment of the Fourth Czechoslovak Republic in 1948.
