Franklin’s diplomatic career was now to begin in earnest. Although the petition to change Pennsylvania into a royal province under the direct rule of the crown was, fortunately, not acted upon and not very seriously pressed, he, nevertheless, continued to believe that such a change would be beneficial and might some day be accomplished. He looked upon the king as supreme ruler of the colonies, and retained this opinion until he heard of actual bloodshed in the battle of Lexington. The king and not Parliament had in the beginning given the colonies their charters; the king and not Parliament had always been the power that ruled them; wherefore the passage by Parliament of stamp acts and tea acts was a usurpation. This was one of the arguments in which many of the colonists had sought refuge, but few of them clung to it so long as Franklin. Almost immediately after his arrival in London in December, 1764, the agitations about the proposed Stamp Act began, and within a few weeks he was deep in them. His previous residence of five years in London when he was trying to have the proprietary estates taxed had given him some knowledge of men and affairs in the great capital; had given him, indeed, his first lessons in the diplomat’s art; but he was now powerless against the Stamp Act. The ministry had determined on its passage, and they considered the protests of Franklin and the other colonial agents of little consequence. The act passed, and Franklin wrote home on the subject one of his prettiest letters to Charles Thomson: “Depend upon it, my good neighbor, I took every step in my power to prevent the passing of the Stamp Act. But the tide was too strong against us.... The nation was provoked by American claims of independence, and all parties joined in resolving by this act to settle the point. We might as well have hindered the sun’s setting. That we could not do. But since it is down, my friend, and it may be long before it rises again, let us make as good a night of it as we can. We may still light candles. Frugality and industry will go a great way towards indemnifying us. Idleness and pride tax with a heavier hand than kings and parliaments. If we can get rid of the former we may easily bear the latter.” Grenville, in conformity with his assurance that the act would work satisfactorily even to the Americans, announced that stamp officers would not be sent from England, but that the kind mother would appoint colonists, and he asked the colonial agents to name to him honest and responsible men in their several colonies. Franklin recommended his old friend John Hughes, a respectable merchant of Philadelphia, never dreaming that by so doing he was getting the good man into trouble. But as soon as Hughes’s commission arrived his house was threatened by the mob and he was forced to resign.
