He was deemed a wise and just Prince, and it is believed that his policy led him to seek the aid of the States of Europe in order to improve the position and condition of himself and his kingdom.

It is said that Pope Boniface VIII endeavoured by a display of his connection with Ghazan Khan to excite the Christian princes to another Crusade, and it was probably this connection with the head of the Christian Church which led to a general impression among Western writers that Ghazan Khan was not sincere in his conversion to Mohammedanism, and was at heart a Christian.

There is reason to think that the secret spring of his action was to weaken the Egyptian Empire, which he regarded as hostile and dangerous to himself and Persia.

It is not clear whether Ghazan Khan apostatized from the religion of his ancestors or that of the Christians, but he is believed to have been attached all his life to the latter faith, though he does not appear to have made a public declaration of his belief in its doctrines.

He professed Mohammedanism in order to obtain the crown, but his life had been passed in friendship with Christians, and in wars with the followers of the faith he adopted.
Xenophon mentions that the royal emblem of Persia from early times was a golden eagle with outstretched wings, resting on a spearhead like the Roman eagle, but he makes no allusion to a standard.
