The patriots who fought in the Revolution did so in the name of preserving traditional rights of Englishmen—especially the right of "no taxation without representation"; they increasingly opposed attempts by Parliament to tax and control the fast-growing colonies. In 1773, when the British imposed heavy sanctions on the Massachusetts colony in the wake of the Boston Tea Party, self described patriots organized colony-by-colony resistance through organizations such as the Sons of Liberty. Fighting broke out in the spring of 1775, and all Thirteen Colonies entered into open rebellion against the crown. In July 1776, the Second Continental Congress declared independence from the United Kingdom and became the de facto national government espousing the principles of Life, Liberty, and the Pursuit of Happiness. The patriots formed a consensus around the ideas of republicanism, whereby popular sovereignty was invested in a national legislature instead of a King.
