"The History of the Decline and Fall of the Roman Empire" by Edward Gibbon is a six-volume historical work published between 1776 and 1788. This monumental chronicle spans from 98 to 1590, tracing the Roman Empire's peak through its collapse, early Christianity's rise as state religion, the fall of Byzantium, and the ascent of figures like Genghis Khan. Gibbon controversially argued that Christianity contributed to Rome's decline by weakening civic virtue, sparking debates that continue today about the true causes of empire's end.
