Öljeytü Khan (Mongolian: Өлзийт; Mongolian script: ; ), born Temür ( ; ; October 15, 1265 – February 10, 1307), also known by his imperial Chinese temple name Emperor Chengzong of Yuan (), was the second emperor of the Yuan dynasty of China, ruling from May 10, 1294 to February 10, 1307. Apart from Emperor of China, he is considered as the sixth Great Khan of the Mongol Empire, although it was only nominal due to the division of the empire. He was an able ruler of the Yuan dynasty, and his reign established the patterns of power for the next few decades. Temür was a son of the Crown Prince Zhenjin and a grandson of the Yuan founder Kublai Khan. During his rule, he achieved the nominal suzerainty of all Mongol states of the time. He showed respect for Confucianism, and called off invasions of Burma (Pagan), Đại Việt and Kamakura Japan. However, his reign was beset by corruption and administrative inefficiencies. Early life Named as the "blessed iron Khan" in the Mongolian language, Temür was born the third son of Zhenjin of the Borjigin and Kökejin (Bairam-Egechi) of the Khunggirad on October 15, 1265. Because Kublai's first son Dorji died early, his second son and Temür's father, Zhenjin, became the crown prince. However, he died in 1286 when Temür was 21 years old. Kublai remained close to Zhenjin's widow Kökejin, who was high in his favor. Like his grandfather Kublai, Temür was a follower of Buddhism. Temür followed his grandfather Kublai to suppress the rebellion of Nayan (Naiyan) and other rival relatives in 1287. Then he and Kublai's official, Oz-Temür, came to guard the Liao River area and Liaodong in the east from Nayan's ally, Qadaan, and defeated him. Kublai appointed Temür the princely overseer of Karakorum and surrounding areas in July 1293. Three Chagatai princes submitted to him while he was defending Mongolia (they fled to Chagatai Khanate soon and returned to Yuan dynasty again during the reign of Temür). After Kublai Khan died in 1294, Kublai's old officials urged the court to summon a kurultai in Shangdu. Because Zhenjin's second son Darmabala had already died in 1292, only his two sons, Gammala and Temür, were left to succeed. It was proposed that they hold a competition over who had better knowledge of Genghis Khan's sayings. Temür won and was declared the emperor. Reign Following in the
