O Tannenbaum
Florida, which became a U.S. state in 1845, did not have a state song until 1913. On May 12, 1913, Governor Park Trammell signed a bill which designated "Florida, My Florida" as the state song. "Florida, My Florida" was sung to the tune of the German Christmas song "O Tannenbaum", whose tune was also used for the official state songs of Maryland ("Maryland, My Maryland") and Iowa ("The Song of Iowa"), and for the unofficial state song of Michigan ("Michigan, My Michigan"). In 1935, a resolution changed the state song to "Swannee River" .
