Horst Wessel (October 9, 1907 – February 23, 1930) was a German Nazi activist and an SA-Sturmführer who was made a posthumous hero of the Nazi movement following his violent death in 1930. He was the author of the lyrics to the song "Die Fahne hoch" ("The Flag On High"), usually known as Horst-Wessel-Lied ("the Horst Wessel Song"), which became the Nazi Party anthem and, de facto, Germany's co-national anthem from 1933 to 1945.
Horst Wessel was a squad leader in the SA who was killed by communists in 1930. Goebbels turned him into the NSDAP hero martyr. A song Wessel had written was elevated into the co-national anthem known as the Horst Wessel-Lied.
