What makes the "Join or Die" ad by Benjamin Franklin effective in the French and Indian War debate?
This AP question from the Document Based Quiz addresses the degree of unity in the colonies by the time of the Revolution. While it took some time, the colonies did eventually unite to contribute money and militia to the British effort against the French, especially on the frontier.
What makes Franklin's ad in The Pennsylvania Gazette effective is that it appeals to fear among the colonists that their future was uncertain and that, unless the colonies cooprated and got behind the British war effort, they could still lose the war, and possibly their lands. In addition, the graphic choice of the snake chopped into pieces, labeled with the individual colonies gave people a stark visual. This was especially compelling. It also put his Albany Plan of Union into simple terms that average citizens of the time could understand.
