 In 1905 , Dmowski moved to Warsaw , back in the Russian partition of Poland , where he continued to play a growing role in the Endecja faction . During the Russian Revolution of 1905 , Dmowski favoured co @-@ operation with the Imperial Russian authorities and welcomed Nicholas II 's October Manifesto of 1905 as a stepping stone on the road towards renewed Polish autonomy . During the revolt in Łódź in June 1905 , the Endeks , acting under Dmowski 's orders , opposed the uprising led by Piłsudski 's Polish Socialist Party ( PPS ) . During the course of the " June Days , " as the Łódź uprising is known , a miniature civil war raged between Endecja and the PPS .
