Kebek

Kebek became Khan of the Chagatai Khanate in 1309, succeeding his brother Esen Buqa I. His reign focused on administrative and economic reforms, moving the khanate toward greater stability and centralization.

Kebek introduced a standardized silver coinage system across the Chagatai Khanate, replacing the diverse local currencies. The coins, known as 'Kebek dirhams,' facilitated trade and tax collection, strengthening the khanate's economy.

Kebek reorganized the Chagatai Khanate's administration, dividing it into provinces (tumens) governed by appointed officials. He also established a centralized tax system and a postal relay network, improving governance and communication.

Kebek's forces were defeated by the Yuan dynasty in a border conflict in 1314. The loss forced him to pay tribute to the Yuan, acknowledging their supremacy and ending Kebek's expansionist ambitions in the east.
