Mongke Khan was the fourth khan of the Mongol Empire and ruled during the mid-13th century. He made significant reforms in the Mongol Empire and left his mark as one of the most powerful Mongol emperors. During Mongke Khan’s reign, the rapidly spreading Mongol Empire was reaching the borders of the Kingdom of Cilicia. The diplomatic approach of King Hetoum I, who was then the King of Cilicia, prevented the possible war between the two powerful armies. Later on, Hetoum traveled to Karakorum (Mongolia) and, together with Mongke Khan, they signed a peace agreement.
