This article combines prosopographical analysis of the episcopate between 1307 and 1330 with examination of its participation in the politics of the time – baronial unrest, the deposition of Edward II and a regency dominated by his queen and her paramour. Elevation to the episcopate brought status, an opportunity for career clerks. Nobles were not prominent among bishops, nor were regular clergy; curiales were, but more numerous were university men. The differing roles of archbishops Winchelsey, Reynolds, Mepham, and to a marginal extent Stratford, are reviewed. Crucial is the reaction of prelates to the crisis of 1326–7. Diagrams and tables help to quantify the conclusions reached.
