It was written by Fred Small to commemorate the saving of the Danish Jews from Hitler by the rest of the Danes.

The rescue of the Danish Jews occurred during Nazi Germany's occupation of Denmark during World War II. On October 1, 1943 Nazi leader Adolf Hitler ordered Danish Jews to be arrested and deported. Despite great personal risk, the Danish resistance movement with the assistance of many ordinary Danish citizens took part in a collective effort to evacuate about 7,800 Jews of Denmark by sea to nearby neutral Sweden.

The rescue allowed the vast majority of Denmark's Jewish population to avoid capture by the Nazis and is considered to be one of the largest actions of collective resistance to repression in the countries occupied by Nazi Germany. As a result of the rescue and Danish intercession on behalf of the 5% of Danish Jews who were deported to Theresienstadt transit camp in Bohemia, over 99% of Denmark's Jewish population survived the Holocaust.

I think I misposted on the other thread (greatest anti-war song) that t was 2000. It was an amazing feat as there were 8000 Jews in Denmark at that time. If you go to the link it explains how the Danes were able to protect the Jews prior to that time.
