The title of the cartoon by Benjamin Franklin is "Join, or Die". It is a depiction of several of the 13 British colonies in what later became the United States of America as separate segments of a rattlesnake. South of New England are segments for the colonies of New York, New Jersey, Pennsylvania, Maryland, Virginia, North Carolina, and South Carolina. The colonies of Delaware and Georgia are not represented in the cartoon. By means of this cartoon, Frankin was expressing the need for the British colonies to join in order to be able to defeat the French and their Indian allies in the French and Indian war. This cartoon was first published in 1754, and it was revived twelve years later, at the onset of the American Revolution.
