Presbyterian system was set up. It was not, however, fully carried out, and all manner of ministers were in possession when the Protectorate was set up in 1653. The cathedral services had long been silenced, and in 1650 Cromwell used the buildings as a convenient accommodation for the Scottish prisoners captured at Dunbar. On the petition of the people of the county, the Protector undertook to establish a college in Durham and to devote the cathedral and castle buildings to that purpose. Resentment and discontent smouldered during these years of tyranny. Indeed, more than one Royalist rising had to be repressed. When, at the beginning of 1660, there was talk of restoring the King, no voice of dissent was heard in the county. Exuberant loyalty greeted the Restoration. Cosin was made Bishop. He was one of the group of influential men appointed by Neile forty years before, and now for twelve years he repaired the breaches of the city and diocese, and carried out the principles which he had formed in earlier life. The Palatinate jurisdiction was revived, with perhaps greater lustre than it had exhibited for a century past. In these days of royalist triumph Nonconformist and Puritan scarcely ventured at first to show their heads, but in Durham they were only biding their time. They found opportunity to promote a formidable rising, which was known as the Derwentdale Plot, aiming at some kind of overthrow of the restored Church and Crown. It was badly managed, and speedily collapsed; but Anabaptists, Quakers, and other parties managed to maintain their existence despite strenuous measures, and more particularly despite the vigorous working of the Conventicle Acts which were intended to crush Nonconformity.
