Under Kublai Khan the Mongol empire reached its largest extension. He ruled over 24000000 km² (nearly 10000000 mi²). The empire went from China and Korea to Iran and southern Russia, from the Korean peninsula to the Danube River.
During Kublai's reign the empire was divided into four smaller Kanatos but he still remained as the Great Khan of all of them. He was actually the first Khan to successfully conquest China in 1279, making him the first Yuan ruler of the whole China. After his death, the mongols didn't elect a new Khan and the Kanatos became more independent.

In other words this could be a direct answer to Martin Luther and his 95 thesis, in which the selling of the indulgences, that is the forgiveness of sins in exchange of money, was the main issue. The Church states that the Christ himself gave the right to them to sell the indulgences and that that is the time-honored tradition.
