“Poles and Lithuanians have experienced many repressions from the Soviet security organs, which ruthlessly fought against all attempts of regaining independence by both countries. It's an experience which unites us and is worth remembering about, because it was frequently associated with heroic resistance to communism’, - President of the IPN, Jarosław Szarek told PAP on Tuesday.

The President of the IPN stressed the fact that institutional cooperation between Poland and Lithuania is a natural continuation of the centuries-old neighborhood of both countries”. - We must remember that heritage: the Polish-Lithuanian Commonwealth, as well as the nineteenth century, when, for example, during the January Uprising, both Poles and Lithuanians, side by side, fought against Tsarist Russia for freedom, singing the song " Obok Orła znak Pogoni " - stressed Dr Szarek. He also pointed out that both nations were victims of the Molotov-Ribbentrop Pact of August 1939, as a result of which Poland and Lithuania lost their independence for decades.
