Problem zachodniej granicy Polski oraz zjednoczenia Niemiec w polityce zagranicznej rządu Tadeusza Mazowieckiego (1989-1990)

Following the fall of the Berlin Wall, the main problem in the international policies of Tadeusz Mazowiecki's government was to guarantee the Polish western border before the reunification of Germany took place. In the face of Chancellor Helmut Kohl's opposition to the idea, the Polish government undertook a wide diplomatic action trying to convince the leaders of the USSR, USA, Great Britain and France to make the governments of the FRG and GDR initiate a border treaty before the reunification of both German states. Finally, Mazowiecki's government managed to safeguard the participation of its representative in the Two Plus Four Conference, at which the conditions for the reunification were established. One of them was about the confirmation of the border between Germany and Poland and abandonment of any territorial claims in the future.
