In 1679 fear of Catholicism triggered a last orgy of persecution. The so called Popish Plot, to murder the king and seize the throne, was a paranoid fantasy concocted by Titus Oates, but it unleashed a wave of gruesome executions, including the judicial murder of the Catholic Archbishop of Armagh, Oliver Plunkett.

At the height of the hysteria, Protestant mythology achieved definitive form in a book that would shape the writing of Tudor history down to our own day. In 1679 Gilbert Burnet, a Scottish cleric, published the first volume of a massive History of the Reformation, an anti-Catholic narrative given scholarly credibility by the inclusion of dozens of documents gathered from public and private archives. Burnet would be the chief propagandist for the “Glorious Revolution” which deposed James II and set the Protestant William of Orange on the throne. His history rammed home the message that Catholicism and Englishness were utterly incompatible: Catholicism was tyranny, Protestantism liberation. “They hate us,” he wrote, “because we dare to be freemen and Protestants.”
