In the early 1410s several fellows of Oriel took part in the disturbances accompanying Archbishop Arundel's attempt to stamp out Lollardy in the University; the Lollard belief that religious power and authority came through piety and not through the hierarchy of the Church particularly inflamed passions in Oxford, where its proponent, John Wycliffe, had been head of Balliol. Disregarding the provost's authority, Oriel's fellows fought bloody battles with other scholars, killed one of the Chancellor's servants when they attacked his house, and were prominent among the group that obstructed the Archbishop and ridiculed his censures.
