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".
