恭帝
The Song imperial family surrendered to the Yuan in 1276, making the Mongols the first non-Han Chinese peoples to conquer all of China. Three years later, Yuan marines crushed the last of the Song loyalists. The Song Empress Dowager and her grandson, Emperor Gong of Song, were then settled in Khanbaliq where they were given tax-free property, and Kublai's wife Chabi took a personal interest in their well-being. However, Kublai later had Emperor Gong sent away to become a monk to Zhangye.
