In the newly independent Second Polish Republic, the ND was represented first by the "Popular National Union" (Związek Ludowo-Narodowy), a conservative political party advocating their program through democratic and parliamentary political means. After Piłsudski's May 1926 "Coup d'État", the ND found itself in constant opposition to his "Sanacja" government. The tightening of Sanacja's controls on opposition parties and its general authoritarian drift led to the gradual radicalization of the ND movement. In December 1926, the "Camp of Great Poland" (Obóz Wielkiej Polski) was created as an extra-parliamentary organization in opposition to the Sanacja government. The youth faction of the Camp of Great Poland gradually took control over the whole organization, and from 1931 the camp quickly radicalized and even adopted some militaristic elements.
