Hail! Minnesota was adopted as the state song in 1945.
“Hail! Minnesota,” was written in 1904 by University of Minnesota students Truman E. Rickard and Arthur E. Upson. A second verse was penned in 1905. The University of Minnesota Alumni Association, owner of the copyright to the song, released its copyright to the words and music, and in 1945 the Legislature adopted “Hail Minnesota” as the state song.
