Warschauer Vertrag
On 27 June 1972, however, – in response to West Germany's change in Ostpolitik and the Treaty of Warsaw – Pope Paul VI reversed the diocesan boundary along the post-war borders. The Apostolic constitution "Vratislaviensis - Berolinensis et aliarium" disentangled the East Brandenburgian diocesan area (becoming thus the Diocese of Gorzów) and the Farther Pomeranian diocesan area (becoming the new westerly Diocese of Szczecin-Kamień and the easterly Diocese of Koszalin-Kołobrzeg).
