Should students of Tudor political thought be interested in a feisty Swiss republican who hardly set foot outside his home canton of Zurich, and a Florentine aristocrat who spent just five years of his career in England? This book presents the case for including two leading lights of the Schola Tigurina—Heinrich Bullinger and Peter Martyr Vermigli—among the chief architects of the protestant religious and political settlement constructed under Edward VI and consolidated under Elizabeth I. Through study of selected texts of their political theology, this book explores crucial intellectual links between England and Zurich which came to exert a significant influence on the institutions of the Tudor church and commonwealth.
