Christendom. The plans were approved but nothing concrete was done. James I of Aragon wished to organize the expedition at once, but this was opposed by the Knights Templar. The Franciscan friar Fidentius of Padua, who had experience in the Holy Land, was commissioned by the pope to write a report on the recovery of the Holy Land. Ambassadors of the Khan of the Tatars negotiated with the Pope, who asked them to leave Christians in peace during their war against Islam. The Mongol leader Abaqa Khan sent a delegation of 13-16 Mongols to the Council, which created a great stir, particularly when their leader underwent a public baptism. Among the embassy were David of Ashby, and the clerk Rychaldus. According to one chronicler, "The Mongols came, not because of the Faith, but to conclude an alliance with the Christians". Abaqa's Latin secretary Rychaldus delivered a report to the Council, which outlined previous European-Ilkhanid relations under Abaqa's father, Hulagu, where after welcoming the Christian ambassadors to his court, Hulagu had agreed to exempt Latin Christians from taxes and charges, in exchange for their prayers for the Qaghan.

Richardus told the assembly that even after Hulagu's death, Abaqa was still determined to drive the Mamluks from Syria.

The Pope's death in 1276 put an end to any such plans, and the money that had been gathered was instead distributed in Italy.
