Alexios I Komnenos vs Li Cunxu

Alexios I Komnenos was defeated by the Norman army under Robert Guiscard at Dyrrhachium. The Byzantine forces were routed, and Alexios barely escaped. This loss allowed the Normans to occupy much of the western Balkans, though Alexios later recovered some territory.

Alexios I implemented a series of reforms to restore Byzantine power. He reorganized the army by relying more on foreign mercenaries, reformed the currency (the hyperpyron), and granted tax exemptions to the Church. These measures stabilized the empire after decades of decline.

Alexios I sent envoys to Pope Urban II at the Council of Piacenza, requesting military aid against the Seljuk Turks. This appeal contributed to Urban's call for the First Crusade at the Council of Clermont later that year, initiating the Crusader movement.

Alexios I cooperated with the Crusader army to besiege and capture Nicaea from the Seljuk Turks. The city was surrendered to Byzantine control, and Alexios used the Crusaders to recover key territories in Anatolia, though tensions later arose over land claims.

Li Cunxu inherited the title Prince of Jin from his father Li Keyong. He continued the struggle against Later Liang, consolidating the Jin state as a major power in northern China.

Li Cunxu's Jin army defeated the Later Liang forces under Zhu Wen at Baixiang. This victory established Jin as the dominant military power in the north and marked a turning point in the war.

Li Cunxu led a successful campaign against Later Liang, capturing its capital Kaifeng and ending the dynasty. He then proclaimed himself emperor, founding the Later Tang dynasty.

Li Cunxu declared himself emperor of the Later Tang dynasty, claiming legitimacy as the restorer of the Tang lineage. He established his capital at Luoyang and reunified much of northern China.

Li Cunxu faced a mutiny by his own troops at Xingyuan during a campaign against the Khitans. He was killed in the fighting, leading to the collapse of Later Tang and the rise of Later Jin.
