Give Me Liberty by Patrick Henry (1736 - 1799)

This speech was given March 23, 1775, at St. John's Church in Richmond, Virginia, and is credited with having singlehandedly convinced the Virginia House of Burgesses to pass a resolution delivering the Virginia troops to the Revolutionary War. In attendance were Thomas Jefferson and George Washington. Reportedly, the crowd, upon hearing the speech, jumped up and shouted, "To Arms! To Arms!" (Summary from Wikipedia)
