Frequently asked questions

Alexander IV, born Rinaldo di Jenne, was the 181st pope, reigning from 1254 to 1261. The key thing to remember is that he marked the height of the medieval papacy by supporting the mendicant orders (Franciscans and Dominicans) and by fighting against the Hohenstaufen dynasty. Less famous than Innocent III, he nonetheless used his bull Quasi lignum vitae to secure the right of the mendicant friars to teach at the University of Paris, a turning point for medieval education.

  • Entrusted the Inquisition to the mendicant orders (Dominicans and Franciscans) and supported their growth in the universities

Works & Achievements

Bull “Quasi lignum vitae” (1255)

A major ruling that upheld the right of the Franciscans and Dominicans to teach at the University of Paris, against the secular masters.

Canonization of Saint Clare of Assisi (1255)

Official recognition of the sainthood of the founder of the Poor Clares, a resounding show of support for the mendicant orders.

Excommunication of Manfred of Sicily (1258)

Condemnation of the Hohenstaufen king, extending the papacy's struggle against the Swabian dynasty in southern Italy.

Support for the missions and the Inquisition (1254-1261)

Confirmation of the mendicant orders' role in preaching, missions, and the fight against heresy.

Appeals against the Mongol threat (1260)

Diplomatic efforts to warn and rally Christendom in the face of the advancing Mongol armies in Eastern Europe.

Attempts at reconciliation with the Greek Church (1254-1261)

Initiatives to bring the Eastern and Western Churches closer together amid the Byzantine reconquest.

Anecdotes

Elected pope in 1254 under the name Alexander IV, Rinaldo di Jenne was the nephew of Pope Gregory IX: the family of the counts of Segni had already given the Church several popes, including Innocent III. Nepotism and the great Roman families played a central role in the election of the sovereign pontiffs in the 13th century.

As early as 1255, Alexander IV canonized Clare of Assisi, the faithful companion of Saint Francis and founder of the Poor Clares, barely two years after her death. This swift gesture shows the pope's deep attachment to the then very recent mendicant orders.

Alexander IV almost never managed to reside in Rome itself: the city was too turbulent and hostile. He spent most of his pontificate in Viterbo and Anagni, towns in Latium where the papacy found refuge.

In 1255, the pope firmly defended the Franciscan and Dominican friars against the masters of the University of Paris who wanted to drive them out of teaching. Through his bull “Quasi lignum vitae”, he upheld their right to teach, marking a victory for the mendicant orders in the universities.

Worried about the advance of the Mongols, who had devastated Poland and Hungary, Alexander IV sought to organize the resistance of Christendom and sent appeals to the princes of Europe to prepare for a possible invasion.
