England in the Age of Wycliffe (Barnes & Noble Digital Library)

This 1899 study, which was Trevelyan's doctoral dissertation, is less a biography of the English cleric who led the 14th century Lollard movement than a general picture of English society, politics, and religion at the time, focusing on Wycliffe as a central figure. Specifically, Trevelyan describes a poor class of people, a corrupt church, a powerless king, among other issues.
