Béla Kun
Also, right before getting banned, Kassák had a public confrontation with Béla Kun, the commissioner of the Hungarian commune. At the time, Kassák was a member of the Writer’s Directory but he soon withdrew following his clash with Béla Kun. The polemics he rendered in this first public debate was published as one of the editions of "MA" under the title, “Letter to Béla Kun, in the Name of Art”. After the collapse of the Republic of Councils, to avoid counter-revolutionary backlash, and to escape an arrest warrant issued against him, Kassák emigrated to Vienna in 1920.
