Roman Dmowski

Roman Stanisław Dmowski (Polish: [ˈrɔman staˈɲiswaf ˈdmɔfski], in official Russian documents Рома́н Валенти́нович Дмо́вский; 9 August 1864 – 2 January 1939) was a Polish politician, statesman, and co-founder and chief ideologue of the National Democracy (abbreviated "ND": in Polish, "Endecja") political movement active during the interwar period.

While he never wielded significant political power except for a brief period in 1923 as Minister of Foreign Affairs, Dmowski was one of the most influential Polish ideologues and politicians of his time. A controversial personality most of his life, Dmowski desired a homogeneous, Polish-speaking and Roman Catholic-practicing nation. Throughout most of his life, he was the chief ideological opponent of the Polish military and political leader Józef Piłsudski and of the latter's vision of Prometheism, a multi-ethnic Poland reminiscent of the Polish–Lithuanian Commonwealth.
