"Storia della decadenza e rovina dell'impero romano, volume 11" by Edward Gibbon is a historical work published between 1776-1789. This monumental six-volume masterpiece traces Western civilization from the Roman Empire's height through the fall of Constantinople in 1453. Using primary sources in an unprecedented way, Gibbon examines the behaviors and decisions that led to Rome's long decline. His controversial chapters on Christianity's role sparked fierce debate, while his ironic, pessimistic tone became characteristic of Enlightenment historical writing.
