In this book, D. Burr, one of the world's leading authorities on the Franciscans, offers the first comprehensive history of the so-called Spiritual Franciscans, a protest movement within the Franciscan order. Burr shows that the movement existed more or less as a loyal opposition in the late thirteenth century, but by 1318 Pope John XXII and leaders of the order had combined to force it beyond the boundaries of legitimacy. At that point the loyal opposition turned into a heretical movement and recalcitrant friars were sent to the stake.
