Paul Revere is best known in American history for being one of the men who tried to ride to Lexington and Concord to warn that British troops were moving in that direction on April 18, 1775. However, his actions that night were exaggerated and are not Revere's main importance.
Instead, Revere is most important as a political organizer and propagandist. Revere was a member of the Sons of Liberty and did such things as helping to plan the Boston Tea Party. Perhaps his biggest contribution was his engraving of the Boston Massacre. This engraving was very biased and was used as a way of stirring up anger against the British.
