# Crusade against Francesco Ordelaffi

The crusade against Francesco Ordelaffi (1356–1359) was an international military campaign to restore the temporal power of the Holy See over part of the Romagna. Resistance was led by Francesco II Ordelaffi, lord of Forlì and Cesena. The crusaders were initially successful in detaching Ordelaffi's allies. The intervention of mercenaries on Ordelaffi's side changed the nature of the war. Papal authority was eventually reimposed with the help of Hungarian troops.

## Background

In 1353, Innocent VI, then ruling from Avignon, sent Cardinal Gil de Albornoz to Italy to restore papal authority in the Papal States. He met the greatest resistance from Ordelaffi and Manfredi. In October 1354, he had them declared heretics "on the grounds of contumacy".
On 17 January 1356, Pope Innocent VI pronounced a crusade against Ordelaffi and his allies, Giovanni Manfredi, lord of Faenza, and his brother Guglielmo Manfredi. He accused them of unlawfully occupying Castrocaro, Meldola and Bertinoro and governing tyrannically. The crusade was led by Albornoz, who in February ordered it preached in the archdiocese of Ravenna and the patriarchates of Grado and Aquileia.
Ordelaffi's allies at the start of the crusade were the Lordship of Milan under Bernabò Visconti and the Republic of Venice.

## Campaign

The crusade achieved early successes with troops supplied by the House of Anjou. On 1 July, Innocent VI asked King Louis I of Hungary to send troops and to permit the Hungarian church to send raise troops. On 17 July, an agreement was reached. Louis was appointed standard-bearer of the Church (4 August) and granted a three-year tenth to cover his expenses (11 August). He was to provide troops to Albornoz upon request and in exchange the pope sanctioned his intervention in the civil war in the Serbian Empire as a crusade.
The Manfredi changed sides before the end of the year. In response, Bernabò Visconti secretly hired the Great Company of German mercenaries under Conrad of Landau to assist Ordelaffi. In early 1357, Hungarian troops arrived. In May, anticipating the arrival of the Germans, Albornoz requested Hungarian reinforcements. He also detached the Da Polenta from their alliance with Ordelaffi and laid siege to Cesena, which was defended by Francesco's wife, Cia Ubaldini. Cesena capitulated on 21 June and Bertinoro on 23 June.
The Germans arrived in the Romagna on 18 June 1357. After their initial attempt to enter Tuscany failed, they camped at Forlì on 6 July. During his preaching that month, Albornoz extended the crusade to cover the mercenaries, on the grounds that they were guilty of "aiding heretics" (fautoria heresiae). This was the first time a crusade was declared against mercenaries. Albornoz also reduced the period of service required to receive the crusade indulgence. In Florence, the bishop of Narni declared in a sermon that the indulgence was available to anyone who paid one twelfth of the salary of a man-at-arms for six months. On 26 July, after negotiations with the republic of Florence, the bishop announced that all Florentines who confessed their sins within three months would received the indulgence. In exchange, the republic was to supply the crusade with a set number of troops for a set time. This cost the republic 100,000 florins.
The Florentine contingent fought with the German mercenaries near Forlì on 26–27 July. In August, however, Albornoz neutralized the mercenaries with bribes. This policy was opposed by Florence. In the autumn, Hungary sent troops. Albornoz was replaced as commander by Abbot Androin de la Roche. In December, Innocent thanked King Louis for having sent "a sizeable body of men-at-arms".
After a year with few successes, Albornoz returned to replace Androin in the autumn of 1358. In February 1359, he launched a siege of Forlì. He took Castrocaro, Predappio, Fiumana, Oriolo and Rocca d'Elmici. On 4 July, Ordelaffi surrendered Forlì and the crusade came to a close.
