Denmark’s history has particularly been influenced by its geographical location between the North and Baltic seas, a strategically and economically important placement between Sweden and Germany, at the center of mutual struggles for control of the Baltic Sea (dominium maris baltici). Denmark was long in disputes with Sweden over control of Skånelandene and with Germany over control of Schleswig (a Danish fief) and Holstein (a German fief).

Eventually, Denmark lost these conflicts and ended up ceding first Skåneland to Sweden and later Schleswig-Holstein to the German Empire. After the eventual cession of Norway in 1814, Denmark retained control of the old Norwegian colonies of the Faroe Islands, Greenland and Iceland. During the 20th century, Iceland gained independence, Greenland and the Faroese became integral parts of the Kingdom of Denmark and North Schleswig reunited with Denmark in 1920 after a referendum. During World War II, Denmark was occupied by Nazi Germany, but was eventually liberated by British forces of the Allies in 1945, after which it joined the United Nations. In the aftermaths of World War II, and with the emergence of the subsequent Cold War, Denmark was quick to join the military alliance of NATO as a founding member in 1949.
