Roman Stanisław Dmowski (Polish: [ˈrɔman staˈɲiswaf ˈdmɔfski], 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. He saw the Germanization of Polish territories controlled by the German Empire as the major threat to Polish culture and therefore advocated a degree of accommodation with another power that had partitioned Poland, the Russian Empire. He favoured the re-establishment of Polish independence by nonviolent means and supported policies favourable to the Polish middle class. While in Paris during World War I, he was a prominent spokesman for Polish aspirations to the Allies through his Polish National Committee. He was an instrumental figure in the postwar restoration of Poland's independent existence. 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 Poland as a multinational federation against German and Russian imperialism.
