The article discusses the problems of East German intelligence measures taken in the area of, broadly understood, ‘peaceful revolution’ in Poland. It was possible to retrace these problems through the research conducted at the Poland’s National Remembrance Institute [IPN] and the German Stasi Records Agency [BStU]. Comparative analysis of the material from both sources has made it possible to present all the forms of what was referred to as ‘cooperation’ as well as the antagonisms occurring between the security services in both countries.}, type={Article}, title={GDR’s State Security and Poland in 1989}, URL={http://journals.pan.pl/Content/113045/PDF-MASTER/Historie%2012%203-T.Jaskulowski.pdf}, }
