In 2018 after a century of bilateral relations Poland and Denmark finally delineated their
borders in the middle of the Baltic Sea. After the reestablishment of the Polish state in 1918
its ties to Denmark had been quite turbulent. The great powers established the conditions of
the playing field. As small and intermediate European states the two partners tried to keep
their relationship as amicable as possible. Danish investors were active early in the
establishment of the Port of Gdynia as well as road infrastructure during the interwar years.
Though WW2 dramatically reduced the number of relations Polish Intelligence was still active
in Danish anti-Nazi resistance. During the Cold War the so-called Polish People's Republic and
the Kingdom of Denmark found themselves in opposing camps. The Polish armed forces played a
decisive role in planning wartime operations against Denmark and Schleswig-Holstein. After the
Cold War the former opponents became close allies and partners in the European integration
process. This book brings together prominent scholars from Denmark Poland and Germany to
analyze diplomatic military intelligence and cultural relations across the Baltic Sea from
the end of WW1 to the days of NATO cooperation.
