Why was the poster Join or Die used during the prelude to the American Revolution?

The "Join or Die" poster, created by Benjamin Franklin in 1754, was used during the prelude to the American Revolution to emphasize the importance of colonial unity against British rule. It depicted a segmented snake, symbolizing the colonies, and conveyed the message that disunity would lead to failure. The poster aimed to rally support for collective action, particularly in response to British policies and the threat of external enemies. It became a powerful emblem of American colonial resistance and solidarity.
