It also deals with their relations with their neighbors, the Seljuks of Rome and the Byzantines, and the connection of those relations sometimes to the circle of conflict with the Zengids and the Ayyubids, and the contact of the Armenians with the Latin West in order to confront the Islamic and Byzantine danger, and their subordination to the Zangids during the reign of Prince Malih Taurus and the treaties they signed with the Muslims, leading to the Mongol invasion led by Hulagu of the Levant. And the support of the Armenians for them, and their elimination of the Ayyubid state, and then the defeat of the Mongols in front of the Mamluks in the battle of Ain Jalut in the year 658 AH / 1260 AD
