Chu Suiliang vs Niu Sengru

Chu Suiliang was recognized as one of the Four Great Calligraphers of the early Tang dynasty. He developed a distinctive style known for its elegance and strength. His calligraphy was highly influential and was studied by later generations. Many of his works were preserved as models.

Chu Suiliang was appointed Grand Chancellor (Shangshu You Pushe) by Emperor Gaozong after the death of Emperor Taizong. He was one of the regents entrusted with assisting the young emperor. His appointment reflected his high status as a trusted advisor from the previous reign.

Chu Suiliang strongly opposed Emperor Gaozong's plan to depose Empress Wang and appoint Wu Zetian as empress. He argued that Wu was not of suitable background and that the emperor should not act against tradition. His opposition angered the emperor and Wu Zetian.

After opposing the appointment of Wu Zetian as empress, Chu Suiliang was demoted and exiled to Tanzhou (modern Changsha, Hunan). He was later moved to a more remote post in Guizhou. His exile marked the end of his political career and the rise of Wu Zetian's faction.

Chu Suiliang died in exile in 658 AD at the age of 63. His death occurred in Guizhou, where he had been sent as a local official. He was later posthumously rehabilitated during the reign of Emperor Zhongzong, and his reputation as a loyal minister was restored.

Niu Sengru was appointed as chancellor during the reign of Emperor Muzong of Tang. He became the leader of the Niu faction, which opposed the Li faction led by Li Deyu, initiating decades of factional strife that weakened the Tang central government.

Niu Sengru was dismissed from his position as chancellor as the Li faction gained influence under Emperor Jingzong. This dismissal was part of the ongoing Niu-Li factional struggle, which saw alternating periods of dominance between the two groups.

Niu Sengru died in 849, but his faction continued to influence Tang politics. His leadership of the Niu faction contributed to the long-term instability of the Tang court, as factional infighting diverted attention from pressing administrative and military challenges.
