Abu Muslim al-Khurasani vs Subutai

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.

Subutai and Jebe led a 20,000-man army on a reconnaissance-in-force through the Caucasus and into the Russian steppes. They defeated a coalition of Rus' princes at the Battle of the Kalka River in 1223, demonstrating Mongol military reach.

Subutai commanded the Mongol army that defeated the Khwarezmian forces of Jalal al-Din at the Indus River. The victory destroyed the last major resistance in the Khwarezmian Empire, allowing the Mongols to control Persia and Central Asia.

Subutai served as the primary commander in the final campaign against the Jin Dynasty of northern China. He directed the siege of Kaifeng and the capture of the Jin emperor, completing the Mongol conquest of northern China.

Subutai led the Mongol invasion of Hungary, defeating King B

While Subutai commanded the main army in Hungary, a Mongol detachment under his overall strategy defeated a Polish-German army at Legnica. The victory eliminated the Polish threat and secured the Mongols' northern flank during the invasion of Hungary.
