The most important research aim of this work is to present similarities and differences
in Polish-German relations between 1989 and 2009 both in a bilateral and multilateral
(international) dimension in the light of the main assumptions of the conception of “Polish-
German community of interests”. The author aimed to show the most important manifestations
of the Polish-German cooperation in the post-cold-war period and discuss the most
controversial issues both in an intergovernmental (international) and social dimension.
One of the main research aims of the work is to present the sources and manifestations of
the increase in differences of interests and aims of Poland and Germany between 1998 and
2009 in an international, and, above all, a European dimension, that is in the area in which
a far-reaching similarity of interests between the nations existed between 1989/1990 and
1998 and which has constituted the nature of Polish-German community of interests for
many years. Apart from that, the author aimed to present the most important controversies
appearing at this time in bilateral relations between Poland and Germany, connected with
their historical burdens first of all. Despite flow of time, Polish-German World War II related
arguments were still a very serious burden of Polish-German relations.
