TheExpedition of Collo was a short-lived Aragonese military operation led by KingPeter III of Aragon in June 1282 on the North African coast. The expedition aimed to support the rebellious governor Ibn al-Wazir in seizingConstantine from theHafsid Sultanate. However, the operation arrived too late, as Hafsid forces had already crushed the revolt. Peter III briefly occupied and plundered the port ofCollo, then withdrew, making the expedition a minor but notable episode in Aragonese ambitions in the westernMediterranean.

In January 1281,Peter III of Aragon began military preparations at the request of Ibn al-Wazir, a rebel who sought aChristian army to support his planned landing atConstantine and organize a revolt againstTunis. The expedition was scheduled for April 1282.^[1]

Before the expedition, Peter III signed an agreement with theByzantine Empire and received 30,000 ounces of gold to support the campaign. The expedition was framed as acrusade.^[2]

In April 1282, Ibn al-Wazir revolted and declared himselfEmir ofConstantine. In response, the Hafsid sultan's son, Abu Faris, departed fromBéjaïa and laid siege to Constantine on 9 June 1282. After a one-day siege, Abu Faris' forces captured the city, killing Ibn al-Wazir, his brothers, and all supporters.^[3]

Peter III arrived too late at Collo and engaged only in minor skirmishes against local chiefs reinforced by Abu Faris' troops. He failed to achieve any significant success, despite seeking assistance fromPope Martin IV, who declined to provide support.^[4]

By late August 1282,Peter III of Aragon was recalled toTrapani inSicily due to fears of an attack onMessina, ending the Collo Expedition.^[5]
