"History of the Decline and Fall of the Roman Empire — Volume 3 — Folio format" by Edward Gibbon is a historical work published in 1781. This volume continues Gibbon's monumental examination of the Roman Empire's collapse, spanning from 98 to 1590. Gibbon explores the empire's peak, Christianity's rise as state religion, the Western Empire's fall, and Byzantium's fate. Written with detached yet critical prose, he attributes Rome's decline to lost civic virtue and barbarian invasions, while controversially weighing Christianity's role in weakening imperial strength and redirecting resources from secular affairs.
