The Renaissance Papacy was a period of papal history between the Western Schism and the Reformation. From the election of Pope Martin V of the Council of Constance in 1417 to the Reformation in the 16th century, Western Christianity was largely free from schism as well as significant disputed papal claimants. There were many important divisions over the direction of the religion, but these were resolved through the then-settled procedures of the papal conclave. The popes of this period were a reflection of the College of Cardinals that elected them. The College was dominated by cardinal-nephews (relatives of the popes that elevated them), crown-cardinals (representatives of the Catholic monarchies of Europe), and members of the powerful Italian families. There were two popes each from the House of Borgia, House of della Rovere, and House of Medici during this period. The wealthy popes and cardinals increasingly patronized Renaissance art and architecture, (re)building the landmarks of Rome from the ground up. The Papal States began to resemble a modern nation-state during this period, and the papacy took an increasingly active role in European wars and diplomacy. Popes were more frequently called upon to arbitrate disputes between competing colonial powers than to resolve complicated theological disputes. To the extent that this period is relevant to modern Catholic dogma, it is in the area of papal supremacy. None of these popes have been canonized as a saint, or even regarded as Blessed or Venerable. Overview The period from end of the Western Schism in 1417 to the Council of Trent (1534–1563) is a rough approximation used by scholars to date the Renaissance Papacy and separate it from the era of the Counter-Reformation. History In 1420, the papacy returned to Rome under Pope Martin V. Generally speaking, the Renaissance popes who followed him prioritized the temporal interests of the Papal States in Italian politics. In addition to being the head of the Holy Roman Church, the Pope became one of Italy's most powerful secular rulers, signing treaties with other sovereigns and fighting wars. In practice though, much of the territory of the Papal States was only nominally controlled by the Pope, and in actuality was ruled by minor princes. Control was often contested; indeed it took until the 16th century for the Pope to have any genuine control over all his territories. Numerous popes during this period used Papal finances and armies to enforce and
