The origin of the term "Dixie" was the result of a
ten dollar bill issued by the Citizens Bank of New
Orleans in the early 1800s. Ten is Dix in French.

English speaking Mississippi riverboat men
pronounced the French DIX phonetically in
English.  They would tell each other they were
"headin down river to New Orleans to get them
some of those DIXIES."

(They were going down river to the land of the
Dixie, down to  Dixieland, or Dixie!)

You are listening to a recording of "Dixie" by
Louis Armstrong.
