Zhang Rou

Zhang Rou, a Han Chinese warlord controlling territory in Hebei, submitted to the Mongol Empire under Genghis Khan. He surrendered his strongholds and forces, becoming a vassal. This submission allowed him to retain local power while serving the Mongols, a common pattern among northern Chinese elites.

Zhang Rou was appointed by the Mongols to govern the Hebei region as a semi-autonomous ruler. He administered the area, collected taxes, and provided troops for Mongol campaigns. His governance helped stabilize Mongol control over northern China and integrated local elites into the Mongol system.
