Abstract
Jerzy Braun (1901–1975) began as a scout activist, in subsequent years he became known as a politician, poet, prose writer, playwright, screenwriter, literary critic, philosopher, and theologian. In the inter-war years he founded and edited the periodicals Gazeta Literacka [Literary Gazette] and Zet, he also headed the Hoene-Wroński Society which propagated the thought of Józef Maria Hoene-Wroński. Under the Nazi occupation he founded and headed the underground organization Unia grouping Poland’s leading intellectuals. Unia propounded a universalistic program of integrating nations and states whose outlines Braun had laid down before the war. Braun’s unionism theory, in which he strove for a harmonious combination of national and universal ideas, was based on 19th-century concepts developed by, among others, Bronisław Trentowski, August Cieszkowski and, of course, Józef Maria Hoene-Wroński. Imprisoned by the communists after the war, in the 1960s Braun attended the Vaticanum II sessions as an unofficial ecumenism expert
