Confederation of Independent Poland (KPN, Polish: Konfederacja Polski Niepodległej Polish pronunciation: [kɔnfɛdɛˈratsja ˈpɔlskʲi ɲɛpɔˈdlɛɡwɛj]) was a Polish nationalist 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 1990 presidential election and withdrew during the following one. In the 1991 parliamentary election the party got 7.5% of the vote, while in the 1993 parliamentary election 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 Solidarity Electoral Action, but left it in 1997, before the 1997 parliamentary election, in which it didn't participate. For the 2001 parliamentary elections, it allied itself with Solidarity Electoral Action of the Right (AWSP), 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 has been re-registered with the Polish authorities and took part in the 2009 European parliament elections.
