Competing with science for Franklin's attention was his growing involvement in politics. His election in 1751 to the Pennsylvania Assembly began nearly 40 years as a public official. He used his influence at first mainly to further the cause of his various civic enterprises. But he also became a leader in the long-dominant Quaker party, opposing the Proprietary party, which sought to preserve the power of the Penn family in affairs of Pennsylvania. Franklin devised legislative strategy and wrote powerful resolves on behalf of the Assembly, denying Proprietary exemption from taxation and otherwise defending the right of the elected representatives of the people to regulate their own affairs.
Colonial Rights within the Empire

At first Franklin had not the slightest thought about America's separation from Great Britain. He had grown up with allegiance to Britain and had a deep appreciation of the culture of the country of William Shakespeare, John Milton, Joseph Addison, and Alexander Pope. In 1751 he celebrated the rapid increase of colonial population as a great "accession of power to the British Empire," a big and happy family wherein the prosperity of the parent and the growth of the children were mutually beneficial.Franklin expressed his patriotism by proposing a Plan of Union within the empire at Albany in 1754, and a year later in giving extensive service to Gen. Edward Braddock's expedition to recapture Ft. Duquesne from the French. To defend the empire during the French and Indian War (1754-1763), Franklin persuaded the Quaker Assembly to pass the first militia law in Pennsylvania, appropriate money for defense, and appoint commissioners (including himself) to carry on full-scale war. As the war progressed, he worked with British commanders to win a North American empire for Britain. For 3 decades or more Franklin allied himself in thought and deed with such men as William Pitt, who conceived of Britain as a vital, freedom-extending realm as dear (and useful) to its subjects in Boston and Philadelphia as to those in London or Bristol.
Even in this patriotism of empire, however, the seeds of disaffection appeared. The Albany plan, Franklin noted, dividing power between the king and the colonial assemblies, was disapproved by the Crown "as having placed too much weight in the democratic part of the constitution, and [by] every assembly as having allowed too much to [Royal] Prerogative." Franklin also thought it incredibly selfish for the proprietor of Pennsylvania to try to avoid taxation of his vast lands. He sided, he declared in 1756, with "the people of this province … generally of the middling sort." Thus, when he went to England in 1757 as agent of the Assembly, he was alarmed to hear the president of the Privy Council declare: "You Americans have wrong ideas of the nature of your constitution; you contend the King's instructions to his governors are not laws…. But those instructions … are … the Law of the Land; for the King is the Legislator of the Colonies." Though Franklin worked within the empire to resist this presumption, it was clear from the start that if it continued to dominate, Franklin's empire loyalty would wither and die.
Franklin lived in England from 1757 to 1762, seeking aid in restraining Proprietary power in Pennsylvania, meanwhile enjoying English social and intellectual life. He attended meetings of the Royal Society, heard great orchestras play the works of George Frederick Handel, made grand tours of the Continent, and was awarded honorary doctor's degrees by St. Andrews (1759) and Oxford (1762).Back in America for nearly 2 years (1762-1764), Franklin traveled through the Colonies as deputy postmaster general for North America. In 20 years Franklin vastly improved postal service and at the same time made his position lucrative. He also continued his aid to poorer members of his family, especially his sister, and to the family of his wife, the former Deborah Read, whom he had married in 1730. They had two children, Frankie, who died at 4, and Sally, who married Richard Bache. Deborah Franklin also reared her husband's illegitimate son, William, often his father's close companion, who was appointed governor of New Jersey and was later to be notable as a loyalist during the Revolution. Franklin considered Deborah, who died in 1774, a good wife, mother, and helpmate, though she did not share his intellectual interests or even much of his social life.
Politics occupied most of Franklin's busy months at home. He opposed the bloody revenges frontiersmen visited on innocent Native Americans in the wake of Chief Pontiac's Conspiracy, and he campaigned to further restrict the proprietor's power. On this and other issues Franklin lost his seat in the Assembly (after 13 consecutive victories) in an especially scurrilous campaign. His Quaker party retained enough power, however, to return him to England as agent, commissioned especially to petition that Pennsylvania be taken over as a royal colony - a petition Franklin set aside when the perils of royal government loomed ever larger.
More Radical Position

Franklin played a central role in the great crises that led to the Declaration of Independence in 1776. He first advised obedience to the Stamp Act. But learning of the violent protest against it in America, he stiffened his own opposition, notably in a dramatic appearance before Parliament in 1766, when he outlined, plainly and bluntly, American insistence on substantial self-government. Encouraged by repeal of the act, Franklin again expressed his faith in the grand prospects for America within the empire and worked with Pitt, Lord Camden, and other Englishmen who wanted to liberalize both government at home and relations with the Colonies.Yet Franklin mounted a strong propaganda assault on the Townshend Duties of 1767. In fact, Franklin's position was increasingly untenable. He was in countless official, personal, and sentimental ways committed to the British Empire, but he was more committed to the life-style he knew in America and which he now began to record in his Autobiography. The ideal solution, of course, was to find fulfillment for the life-style under the British flag. He only slowly realized that, at least under the policies of George III and Lord North, the two were incompatible.
Franklin's personal fame, as well as his appointment as agent for Georgia (1768) and for Massachusetts (1770), made him the foremost American spokesman in Britain for 10 crucial years, from 1765 to 1775. Protesting the Tea Act in 1773, he wrote two of his most skillful and famous political satires, An Edict by the King of Prussia and Rules by Which a Great Empire May Be Reduced to a Small One. These were merely the best of hundreds displaying Franklin's clever pen in aid of his chosen causes.In 1774-1775 Franklin's agency in England came to an unhappy end. His friends in Massachusetts, against his instructions, published letters of Governor Thomas Hutchinson that Franklin had obtained in confidence. Exposed as an apparently dishonest schemer, Franklin was chastised before the Privy Council in 1774 and simultaneously deprived of his postmaster general's office. Then, in danger of being imprisoned as a traitor, Franklin continued to work with Pitt and others for conciliation, but the Boston Tea Party, the Coercive Acts, and the buildup of British troops in America doomed such efforts. When Franklin left England in March 1775, he was sure that "the extream corruption … in this old rotten State" would ensure "more Mischief than Benefit from a closer Union" between England and the Colonies.
