Primarily because of the Reformation, political obedience became an increasingly significant issue in Tudor England. The success of Henry VIII's break with Rome resulted partly because the state could use the established church to inculcate in the populace the notion of loyalty to the civil government as a Christian duty. Despite the vacillations of Henrician ecclesiastical policy and the more radical reforming spirit of the Edwardian years, Protestant views on political obedience remained fundamentally stable. The accession of Mary, however, created a critical dilemma for men who had been stressing the duty of obedience to one's ruler. Exile was only a partial solution, though among the exiles a handful of leaders worked out a theory of tyrannicide. Of those who took this course, John Knox in particular confused the issue by simultaneously raising the thorny problem of gynecocracy. Written while Mary Tudor was queen, The First Blast of the Trumpet Against the Monstrous Regiment of Women appeared after Elizabeth's accession, when it was an embarrassment to Protestants. It was left, then, to the Elizabethans to rethink the entire question of political obedience. In the Elizabethan era there was a striking reversal of political theory with respect to the concept of active resistance. Protestant writers retreated from the radical new theory of tyrannicide and returned to the more quiescent position worked out in the early Tudor period. Neither the Calvinist doctrine of the right of lesser magistrates to overthrow tyranny and idolatry nor the assertion of this right by the common people (as espoused by Knox, John Ponet, and Christopher Goodman) was openly advocated by English Protestants, though it is possible that some of them found the Calvinist position acceptable. For their part, the English Catholics who accepted the validity of active resistance did not look for their inspiration to the Marian exiles but reflected a medieval tradition that included such theorists as Manegold of Lautenbach, John of Salisbury, William of Ockham, Marsilius of Padua, and Jean Gerson.1
