Konfederacja Polski Niepodległej (Polish pronunciation: [kɔnfɛdɛˈratsja ˈpɔlskʲi ɲɛpɔˈdlɛɡwɛj], KPN, Polish for: Confederation of Independent Poland) was a political party founded on 1 September 1979 by Leszek Moczulski and others declaring support for the pre-war traditions of Sanacja and Józef Piłsudski. It was the first independent political party that was publicly proclaimed in the Eastern Bloc, it was however unrecognized by the People's Republic of Poland government and its chief activists were arrested several times. It didn't participate in the Polish Roundtable Negotiations.
After the fall of communism, Leszek Moczulski was a candidate in the elections for Polish president, but got only 2.5% of votes in the Polish presidential election, 1990 and withdrew during the following one. In the Polish parliamentary election, 1991 the party got 7.5% of the vote, while in the Polish parliamentary election, 1993 it received 5.7%. In 1996 it suffered a split, with the Konfederacja Polski Niepodległej - Ojczyzna faction under Adam Słomka leaving KPN. KPN then joined Akcja Wyborcza Solidarność, but left it in 1997, before the Polish parliamentary election, 1997, in which it didn't participate. For the 2001 parliamentary elections, it allied itself with Akcja Wyborcza Solidarność Prawicy, but its candidates got 0.08% and the AWSP (which got 5.6%) failed to elect a single representative (the threshold was 8%). In 2004 Leszek Moczulski dissolved KPN, while Słomka declared his KPN-O the main KPN and gathered some members of the now-disbanded Moczulski's KPN. The party was recently officially re-registered with the Polish authorities and took part in the 2009 EU elections.
