The Archive of Opposition is one of the oldest activities of the KARTA Centre. It was established in 1991 as “The Archive of the Polish People’s Republic” and gathered all the materials concerning political life in Poland since 1956 to 1989, especially in connection to the events of 1956, 1968, 1970, 1980. In 1998 the archive changed its name to “The Archive of Opposition”, which reflects greater awareness of the specificity of the opposition in the Polish People’s Republic: its diversity extending beyond merely political actions. In the Archive researchers and journalists can find a very rich, written and visual material on the newest Polish political and social history.
