In 1926, in the aftermath of Piłsudski's May coup d'état, Dmowski founded the Camp of Great Poland ("Obóz Wielkiej Polski"), though he would find himself more of an ideologue than a leader, as he was displaced by new, younger politicians. In 1928 he founded the National Party ("Stronnictwo Narodowe"). He kept publishing newspaper articles, brochures and books. With declining health, he mostly retired from politics by 1930. In 1934, a section of the youth wing of the "Endecja" found Dmowski insufficiently hardline for their taste and broke away to found the more radical National Radical Camp (known by its Polish acronym as the ONR). His last major campaign was a series of political attacks on the alleged "Judeo-Masonic" associates of President Ignacy Mościcki.
