Abu Muslim al-Khurasani vs Liu Guangshi

Abu Muslim al-Khurasani emerged as the leader of the Abbasid revolutionary movement in Khorasan. He organized and mobilized a diverse coalition of disaffected groups, including Arabs, Persians, and Shia Muslims, against Umayyad rule.

Abu Muslim's forces, under the command of Qahtaba ibn Shabib, defeated the Umayyad army at the Battle of the Zab in Iraq. This victory led to the fall of the Umayyad Caliphate and the establishment of the Abbasid Caliphate.

After the Abbasid victory, Abu Muslim was appointed governor of Khorasan, the heartland of the revolution. He ruled the province with near-autonomous power, building a strong army and administering the region effectively.

Caliph al-Mansur, fearing Abu Muslim's growing power and popularity, lured him to the court and had him executed. This act eliminated a powerful rival but also sparked rebellions in Khorasan and other regions.

Liu Guangshi commanded Song forces that defeated a Jin army at Yancheng, using combined infantry and cavalry tactics. The victory boosted Song morale but was not followed up due to peace negotiations.

Liu Guangshi was a key negotiator in the Shaoxing Treaty between the Southern Song and Jin dynasties. The treaty established the Huai River as the border and required Song to pay annual tribute, ending active warfare.

After the Shaoxing Treaty was ratified, Liu Guangshi retired from military service, possibly due to court politics. His retirement marked the end of active Song resistance against the Jin for decades.
