The main events, constitutional changes, and players at the national level have long been known, and the major controversies about them largely resolved. Historians until the late 20th century thought that the causes were: a widespread dissatisfaction or even disgust with the evils, corruptions, failures, and contradictions of the established religion, setting up an undertone of anti-clericalism that indicated a rightness for reform. A secondary influence was the intellectual impact of certain English reformers, such as the long-term impact of John Wycliffe (1328–1384) and his “Lollardy” reform movement, together with a stream of Reformation treatises and pamphlets from Martin Luther, John Calvin, and other reformers on the continent.
