On 12 September 1968, Ryszard Siwiec, accountant and Home Army veteran, died of burns in Warsaw, having protested with an act of self-immolation against the Warsaw Pact invasion of Czechoslovakia. The IPN President honored Siwiec at his memorial in Prague, a copy of the one that stands in Warsaw.

Ryszard Siwiec wrote that no price is too high for liberating the world from communism. That's the legacy he left us, as well as the legacy of Jan Palach and all the others who died in flames so that we could live in a free world,

said Karol Nawrocki, Ph. D.

Karol Nawrocki Ph. D., met also with the management of Czech Institute for the Study of Totalitarian Regimes, Director Ladislav Kudrna, Ph.D., Deputy Director Kamil Nedevedicky and head of the Research Department Prokop Tomek, Ph.D. to discuss cooperation on research, education, exhibitions and publications.
