Answer:
Hamilton served his country in many ways: he fought in the American Revolution against the British; led the efforts to reform the inadequate Articles of Confederation; helped design the American government as outlined in the Constitution; and even secured its ratification by writing the Federalist Papers.
Jefferson chose his words for the Declaration in June 1775, shortly after the war had begun, where the idea of independence from Britain had long since become popular among the colonies. He was inspired by the Enlightenment ideals of the sanctity of the individual, as well as by the writings of Locke and Montesquieu.
