 In 1914 Dmowski praised the Grand Duke Nicholas 's Manifesto to the Polish Nation of 14 August , which vaguely assured the Tsar 's Polish subjects that there would be greater autonomy for " Congress Poland " after the war , and that the Austrian provinces of East and West Galicia , together with the Pomerania province of Prussia , would be annexed to the Kingdom of Poland when the German Empire and Austria @-@ Hungary were defeated . However , subsequent attempts on the part of Dmowski to have the Russians make firmer commitments along the lines of the Grand Duke Nicholas 's manifesto were met with elusive answers . Nonetheless , Dmowski 's pro @-@ Russian and anti @-@ German propaganda succeeded in frustrating Piłsudski 's plans of causing an anti @-@ Russian uprising , and bolstered his position as an important Polish political figure on the international scene , especially with the Triple Entente . In November he became one of the active members of the Polish National Committee .
