Patrick Henry did not back down to the King of England
Henry was one of the first, if not the first, colonial radical against the most powerful monarch in the world. His "Virginia Resolves" of 1765 preceeded the Stamp Act Congress, and Samuel Adams' circular to the Massachusetts General Court in 1768. They all argued against taxation without representation. James Otis' The Rights of the British Colonies Asserted and Proved was written in 1764, but focused on Natural Rights.
