It is possible that the popularity of coon songs may be explained in part by their historical timing: coon songs arose precisely as the popular music business exploded in Tin Pan Alley. However, James Dormon, a former professor of history and American studies at the University of Southwestern Louisiana, has also suggested that coon songs can be seen as "a necessary sociopsychological mechanism for justifying segregation and subordination." The songs portrayed Blacks as posing a threat to the American social order and implied that they had to be controlled.
