November 11, 1417, is a significant date in church history: a pope was elected on German soil during the Council of Constance - a unique event to this day. The uniquely composed conclave chose Cardinal and jurist Oddo Colonna, who took the name Martin V and is considered the first pope of the Renaissance. The schism that had divided Christendom into three factions was over, and there was great hope for a new beginning for the Church. Who was this Oddo Colonna? Why was he elected pope? Was he a pope of reforms? Or was his main concern the restoration of the Papal States? How much was he affected by the Hussite Wars? The richly illustrated book vividly and impressively traces the life and impact of Martin V. It discusses the arduous steps taken in the struggle for reforms and provides an overview of the most important ecclesiastical developments.
