The interest of William Penn having been engaged for some time in the colonization of an American province, and the idea having become familiar to his mind of establishing there a Christian home as a refuge for Friends, and the scene for a fair trial of their principles, he availed himself of many favorable circumstances to become a proprietary himself. In various negotiations concerning New Jersey he had had a conspicuous share, and the information which his inquiring mind gathered from the adventures in the New World gave him all the knowledge which was requisite for his further proceedings. Though he had personal enemies in high places, and the project which he designed crossed the interests of the Duke of York[1] and of Lord Baltimore, yet his court influence was extensive, and he knew how to use it. [Footnote 1: Afterward James II. He was proprietor of New York, and Lord Baltimore of Maryland.] The favor of Charles II and of his brother the Duke of York had been sought by Penn's dying father for his son, and freely promised. But William Penn had a claim more substantial than a royal promise of those days. The crown was indebted to the estate of Admiral Penn for services, loans, and interest, to the amount of sixteen thousand pounds. The exchequer, under the convenient management of Shaftesbury, would not meet the claim. Penn, who was engaged in settling the estate of his father, petitioned the King, in June, 1680, for a grant of land in America as a payment for all these debts. The request was laid before the privy council, and then before the committee of trade and plantations. Penn's success must have been owing to great interest made on his behalf; for both the Duke of York, by his attorney, and Lord Baltimore opposed him. As proprietors of territory bounding on the tract which he asked for, and as having been already annoyed by the conflict of charters granted in the New World, they were naturally unfairly biassed. The application made to the King succeeded after much debate. The provisions in the charter of Lord Baltimore were adopted by Penn with slight alterations. Sir William Jones objected to one of the provisions, which allowed a freedom from taxation, and the Bishop of London, as the ecclesiastical supervisor of plantations, proposed another provision, to prevent too great liberty in religious matters. Chief Justice North having reduced the patent to a satisfactory form, to guard the King's prerogative and the powers of Parliament, it was signed by writ of privy seal at Westminster, March 4, 1681. It made Penn the owner of about forty thousand square miles of territory.
