Béla Kun
Stern wrote left pacifist oriented emphatic expressive poetry, which was published in the magazine "Plamen". He also wrote political feuilletons. One of his feuilletons was devoted to the problem of the Jewish diaspora in the new post-war Europe, for which he was criticized and accused that he represents the Jewish messianism of Bolsheviks, Leon Trotsky and Béla Kun.
