The proprietary government had now been suspended twenty-five years. It had fallen through jealousy of the Catholics, and Charles Calvert, who submitted in his own person to the loss of power for the sake of the religion in which he had grown up, had yielded to the anxieties of a parent, and induced his son and heir, Benedict Leonard Calvert, to embrace the doctrines of the established church. By his own death, in February, 1714, and that of his heir in April, 1715, the title to the province devolved to Charles Calvert, the infant son of the latter, who was also educated in the Protestant faith. The reason for excluding the proprietary family then subsisted no longer; their claims were in fact soon after acknowledged by George I. and their government restored in the person of the infant proprietary, in May, 1715. The only consequence of this event meriting notice, was the imposition of a test-oath, requiring of Catholics the abjuration of the Pretender, and the renunciation of some of the essential points of their faith. Private animosity gave edge to these civil persecutions; Catholics were excluded from social intercourse, _nor permitted to walk in front of the State-House_; swords were worn by them for personal defence. Charles Calvert died in 1751, leaving the province to his infant son Frederic, after acquiring for his administration the praise of moderation and integrity. Yet it was fruitful in internal dissensions, which no policy could have averted. The controversy respecting the extension of the English statutes to the colony, originated in 1722, and was succeeded in 1739 by the disputes relating to the proprietary revenue; controversies full of heat at the time, but which will be more conveniently considered in connexion with some subsequent transactions of the same sort. One dispute may be mentioned here, as indicating the spirit of all the rest. The "Six Nations," a tribe of Indians, occupying a border position between the French and English colonies, had claims to a considerable portion of the territory of Maryland lying along the Susquehanna and the Potomac, and in 1742 it was resolved to depute commissioners to Albany for the purpose of extinguishing them by treaty. The lower house of assembly claiming, however, to participate in the appointment of the commissioners, and also to restrict the amount of expenditure, a dispute arose on this point of prerogative, which was only adjusted, two years after, by the governor's appointing the commission on his own responsibility, and defraying its charges from the ordinary revenue. The claims in question were extinguished by the Indian treaty of Lancaster, in June, 1744.
