Although Crittenden County was formed from Livingston County in 1842, the city of Marion wasn't incorporated until 1851. Marion received it's name from Francis Marion, known as the Swamp Fox, who was an American general in the Revolutionary War. He led his troops against the British by darting out of the South Carolina marshes and vanishing before the Redcoats could retaliate. His effective tactics won him the name of the Swamp Fox.
In April 1999 the idea for Marion to have it's own flag to fly was born. Students of the 5th grade class at Crittenden County Elementary School was responsible for the idea of creating a symbol for a city flag and then having it made.
Th new flag was was presented to the public in July of that same year. It has flown proudly ever since.
