Li Siyuan vs Tiberius II Constantine

Li Siyuan, a general of Shatuo origin, led a mutiny against Emperor Li Cunxu (Zhuangzong) after the emperor's excessive cruelty and mismanagement. The mutiny succeeded, and Li Siyuan was proclaimed emperor of the Later Tang dynasty, restoring order.

Despite being illiterate, Li Siyuan reduced taxes, curbed corruption, and promoted capable officials. He cut court expenses and distributed grain during famines, earning a reputation as a wise and just ruler who stabilized the Later Tang state.

Tiberius II was known for his generosity, reducing taxes, distributing money to the poor, and remitting debts. He spent lavishly on public works and charity, earning him the epithet 'friend of the poor.' However, his spending depleted the treasury that Anastasius I had accumulated.

Tiberius II Constantine was proclaimed emperor by the Byzantine Senate and people after the death of Justin II. He was chosen for his popularity and reputation for generosity. His accession was marked by a distribution of gold to the people and a remission of taxes.

Tiberius II led campaigns against the Avars and Slavs who were raiding the Balkans. He achieved some successes, including the recapture of Sirmium in 582, but the Avars continued to pose a threat. His military efforts were hampered by limited resources and the ongoing war with Persia.

Tiberius II died after a short illness, having named the general Maurice as his successor. He married Maurice to his daughter Constantina and elevated him to co-emperor before his death. This ensured a smooth transition of power and continued the dynasty.
