"Michigan, My Michigan" is a popular anthem in the State of Michigan, and erroneously believed by many to be Michigan's official state song. The actual state song, "My Michigan", was formally adopted in 1937 but remains relatively obscure, due in part to the misconception that the official song is "Michigan, My Michigan".
History
Winifred Lee Brent Lyster of Detroit wrote the original 1862 lyrics of "Michigan, My Michigan" to the tune of "O Tannenbaum" (known in English as "O Christmas Tree"), and which was also the melody of "Maryland, My Maryland". Her husband, Henry, was a physician who rose to be Medical Inspector and Acting Medical Director of III Corps in the Union Army. He served from the First Battle of Bull Run to the Battle of Appomattox Court House. Mrs. Lyster was inspired to write the song after the Battle of Fredericksburg.
Major James W. Long of Grand Rapids wrote new lyrics in 1886 but kept the original tune and original Civil War sentiment. In 1902, Douglas Malloch wrote the current lyrics for a convention of the Michigan State Federation of Woman's Clubs in Muskegon. He deemed them more suitable for a peacetime anthem. A new tune was also composed for the song by composer W. Otto Miessner of Detroit.
