In the late 19th century and the early part of the 20th century, Georgia ranchers came to be known as "Georgia Crackers" by Floridians when they drove their cattle down into the grassy flatlands of central Florida to graze in the winter, stopping where the citrus groves began.
It is documented in Shakespeare's King John (1595): "What cracker is this... that deafes our eares / With this abundance of superfluous breath?"
By the 1760s the ruling classes, both in Britain and in the American colonies, applied the term "cracker" to Scotch-Irish and English settlers of the remote southern back country, as noted in a passage from a letter to the Earl of Dartmouth: "I should explain to your Lordship what is meant by Crackers; a name they have got from being great boasters; they are a lawless set of rascalls on the frontiers of Virginia, Maryland, the Carolinas, and Georgia, who often change their places of abode."
However, other Georgians find the term highly offensive and insulting: "'racker' has a murky history but generally describes poor whites.
for plenty of rural, white southerners, "cracker" is a demeaning, bigoted term .
