Acacius of Amida was a 5th-century Christian bishop who governed the see of Amida in Mesopotamia from 400 until his death in 425. Recognized as a confessor of the faith, he is primarily remembered for his humanitarian efforts during a period of conflict. By liquidating precious church vessels, he successfully raised the funds necessary to ransom seven thousand Persian captives. His diplomatic and charitable actions helped mitigate the suffering of prisoners and contributed to easing tensions between the Roman and Persian empires.
