Shapur I vs Tuoba Tao

Shapur I defeated the Roman emperor Gordian III at Misiche in Mesopotamia. Gordian died during or shortly after the battle, and his successor Philip the Arab signed a peace treaty favorable to the Sassanids, paying a large ransom.

Shapur I captured the Roman emperor Valerian in battle near Edessa. Valerian was taken prisoner and spent the rest of his life in Persian captivity, a humiliation unprecedented in Roman history. Shapur used this victory to extract tribute and territory.

Following the capture of Valerian, Shapur I invaded Syria and sacked the city of Antioch, a major Roman center. The Sassanid army plundered the city and deported many inhabitants to Persia, demonstrating the empire's military reach.

Shapur I commissioned rock reliefs and inscriptions at Naqsh-e Rostam, depicting his victories over Roman emperors. The trilingual inscription (Middle Persian, Parthian, Greek) details his campaigns and the extent of his empire, serving as a key historical source.

Shapur I founded the city of Bishapur in Fars province, modeled partly on Roman urban planning. The city featured a palace with mosaics and reliefs celebrating his victories, becoming a major Sassanid administrative and cultural center.

Emperor Taiwu of Northern Wei (Tuoba Tao) conquered the last rival state, Northern Liang, unifying all of northern China under the Northern Wei dynasty. This ended the Sixteen Kingdoms period and established Northern Wei as the dominant power in the north.

Emperor Taiwu issued an edict suppressing Buddhism, ordering the destruction of monasteries, scriptures, and images. He favored Daoism and sought to reduce Buddhist influence on state affairs. This was the first major persecution of Buddhism in Chinese history.

Emperor Taiwu was assassinated by his eunuch Zong Ai, who feared punishment for his misdeeds. The assassination plunged Northern Wei into a succession crisis, but Zong Ai was soon killed by other officials, and a new emperor was installed.
