The central government of the Southern Song meanwhile was unable to cope with the challenge of the Mongols and new peasant uprisings in the region of modern Fujian led by Yan Mengbiao and Hunan. The court of Emperor Lizong was dominated by consort clans, Yan and Jia, and the eunuchs Dong Songchen and Lu Yunsheng. In 1260, Jia Sidao became chancellor who took control over the new emperor Zhao Qi (posthumous title Song Duzong) and expelled his opponents like Wen Tianxiang and Li Fu. Because the financial revenue of the late Southern Song state was very low, Jia Sidao tried to reform the regulations for the merchandise of lands with his state field law.
