Treaty of Warsaw
On 27 June 1972, however, - in response to West Germany's change in Ostpolitik and the Treaty of Warsaw - Pope Paul VI redrew the diocesan boundaries along the post-war political borders. The Apostolic constitution "Episcoporum Poloniae coetus" disentangled the Polish Pomeranian diocesan area of Berlin, becoming the new westerly Diocese of Szczecin-Kamień and the easterly Diocese of Koszalin-Kołobrzeg).
