Fourth Polish Republic (Polish: IV Rzeczpospolita or IV RP), a plan for moral revolution and political change put forth in 1997 by the Polish conservative philosopher Rafał Matyja in the magazine "Nowe Państwo" ("New Country"). "Fourth Republic" was a political slogan used by the right-leaning Prawo i Sprawiedliwość (PiS) party in the 2005 Polish parliamentary election.
According to PiS, the current Third Polish Republic is a post-communist creation whose very foundations must be changed to create a truly democratic state free of its past.
