To the East China was subdued; to the South the conquest of Hindustan was reserved for the house of Timour or Tamerlane. While the hosts that went forth to conquer Russia, Poland, Hungary, etc., (1235-1245) inscribed on the military roll numbered fifteen hundred thousand men. Holagon the grandson of Jenghiz Khan had but to thrust at the phantom of power which the Caliphs of Bagdad enjoyed when it vanished like the mist. Bagdad after a siege of two brief months, was stormed and sacked and the savage Tartar pronounced the death of the Caliph Mostasem the last of the temporal successors of Mohammed whose noble kinsmen of the race of Abbas had reigned in Asia above five hundred years.
Once more the torrents of woe flow in upon Armenia lying in the track of the Tartar armies westward. Ani is again besieged and soon a famine broke out within the walls and many of the citizens rushed out and gave themselves up to the mercy of their enemies. They were kindly received and a sufficient supply of food was given to them. Induced by this kindness more than half of the inhabitants were soon found in the camp of the Tartars. All at once the poor wretches were divided into small parties under the pretext of receiving better protection when the soldiers fell upon them and massacred every individual. Then the city was easily taken, destroyed by fire and the entire population put to the sword.
Many cities suffered the desolations and horrors of Ani till the Khan ordered his chiefs on to other conquests. Then followed the infliction of a heavy capitation tax on all the remaining provinces--sixty pieces of money being demanded of every Armenian from the age of ten upwards. Those who were unable to pay this sum suffered intolerable tortures. Those who were possessed of lands lost them, their wives and children being seized and sold into slavery. Nothing ever equalled the horrors that now overspread this unhappy country, most of the inhabitants having no money to pay the tax and having no place to which to flee from their oppressors. Finally an embassy to Mangon Khan, a grandson of Jenghiz secured some little alleviation of their misery.
Meantime there was growing up in Cilicia a subordinate kingdom of Armenia with Tarsus for its capital--and receiving favor from the Sultan of Egypt and the Khan of the Tartars. Leo III. resumed the kingly reins of his kingdom comprising all of Modern Anatolia. He repaired his cities; he erected public schools. He caused all the literary productions of the Armenians from the earliest ages to be recopied and distributed among the convents of the kingdom. He reigned for twenty years ardently devoted to the service of God and died in the year 1289.
