The Horst Wessel Song
Horst Wessel was born September 9, 1907, in Bielefeld, Germany. Wessel dropped out of law school and defied his mother by joining the Nazis, becoming an SA storm trooper. He lived in a Berlin slum with a former prostitute. On February 23, 1930, someone (different accounts say it was a political enemy, the woman's former boyfriend, or perhaps her pimp) broke into Wessel's apartment and mortally wounded him.
Joseph Goebbels, the Nazis' propaganda chief, claimed Wessel was murdered by a Communist, and made him a martyr in the party's struggle with their Communist opponents. Wessel was given an elaborate funeral, which was interrupted by stone-throwing Communists. The murder and reaction helped turn public opinion in favor of the Nazis and against the Communists.
A poem Wessel had written was put to music and became the marching song of the SA and later the official song of the Nazi Party and unofficial national anthem of Germany.
