The khanate that grew out of the lands given to Chagatai, the second son of Genghis Khan, and ruled by his descendants over the steppes and oasis cities of Central Asia.
Legend has it that Chagatai was the strictest enforcer of the Yassa, the traditional Mongol code of law. He is said to have insisted even on the rule against washing one's hands in running water, and among his brothers he was known as the one who held everyone to the letter of the law. Reflecting that spirit, the khanate long retained its rugged, nomadic way of life.
Sitting in the heart of Central Asia, it controlled key stretches of the Silk Road. In the west lay the oasis cities of Transoxiana such as Samarkand and Bukhara; in the east lay Almaliq and the grasslands. Wanting the taxes of the cities while refusing to give up the herding life left the khanate straddling two worlds, and that is what eventually tore it apart.
After the Mongol Empire split, the Chagatai Khanate was often at the mercy of stronger neighbours. At the Talas kurultai of 1269 it agreed with Kaidu on how to share land and taxes, but when Baraq marched west against the Ilkhanate the next year, lost badly and died, the khanate fell under Kaidu's influence for a long time.
By the middle of the 14th century the west, which wanted to settle in the oasis cities, and the east, which wanted to stay on the steppe, finally parted. The eastern half became known as Moghulistan, while in the west Timur took power behind a Chagatai khan and built an empire of his own.
