Temur Khan died without an heir and did not designate one. A violent succession conflict resulted among the royal princes.  Eventually one of his nephews emerged from the conflict to take the throne of the Mongolian Empire and the Chinese Yuan Dynasty.  He became Emperor Wuzong (or Kulug Khan).    He made a pact with his younger brother, Ayurbarwada Buyantu, to succeed him.  He became Emperor Renzong.  Together the two brothers ruled China for thirteen years.  The two of them could not have been more different in the directions they took China.  One of the brothers was a military commander from the Asian Steppes before ascending to the throne.  The other brother grew up under Chinese tutelage and tried to further Sinicize the Yuan Government.
