Psamtik I vs Shapur I

Psamtik I expelled Assyrian military garrisons from Egypt, taking advantage of the weakening Assyrian Empire. He used Greek and Carian mercenaries to strengthen his army. This action ended Assyrian control over Egypt and established the Saite dynasty as the ruling power.

Psamtik I unified Egypt after the Assyrian withdrawal, ending the Third Intermediate Period. He established the 26th Saite dynasty and consolidated control over the Nile Delta and Upper Egypt. This reunification restored Egyptian independence and stability after centuries of foreign domination.

Psamtik I encouraged trade with Greece and the Levant, and promoted a revival of traditional Egyptian art and religion. He sponsored the construction of temples and the restoration of ancient monuments. This period, known as the Saite Renaissance, saw a resurgence of Egyptian culture.

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.
