In 1754 a war with France was impending, and Franklin, who by this time had become the most important man in the colony of Pennsylvania, was sent to a congress of commissioners from the different colonies, ordered by the Lords of Trade to convene at Albany, to confer with the chiefs of the Six Nations for their common defence. Franklin there submitted a plan for organizing a system of colonial defence which was adopted and reported; it provided for a president-general of all the colonies to be appointed by the crown, and a grand council to be chosen by the representatives of the people of the several colonies. The colonies so united, he thought, would be sufficiently strong to defend themselves; and there would then be no need of troops from England. Had this course been pursued, the subsequent pretence for taxing America would not have been furnished, and the bloody contest it occasioned might have been avoided. The Lords of Trade, however, feared that any such union of the colonies would reveal to them their strength; and the project of union, though accompanied with a recommendation from the governor of the province of Pennsylvania, when it was brought into the assembly, as it was during Franklin's casual absence from the hall, was rejected. This Franklin thought a mistake. "But such mistakes," he said, "are not new; history is full of the errors of states and princes. Those who govern, having much business on their hands, do not generally like to take the trouble of considering and carrying into execution new projects. The best public measures are there fore seldom adopted from previous wisdom, but forced by the occasion." Instead of allowing the colonists to unite and defend themselves, the home Government sent over General Braddock with two regiments of regular English troops, whom the colonists were expected to maintain. The proprietaries, Thomas and Richard Penn, sons of William Penn, and the hereditary governors of the colonies, however, "with incredible meanness," instructed their deputies--the governors they seat out--to pass no act for levying the necessary taxes unless their vast estates were in the same act exempt. They even took bonds of their deputies to observe these instructions. The assembly finally, "finding the proprietaries obstinately persisted in manacling their deputies with instructions inconsistent not only with the privileges of the people but with the service of the crown,"--we are quoting the language of Franklin,--"resolved to petition the king against them," and appointed Franklin as their agent to go to England and present their petition. He arrived in London on the 27th July 1757, not this time as a poor printer's boy, but as a messenger to the most powerful sovereign in the world from a corporate body of some of his most loyal subjects.
