سقوط الإمبراطورية الرومانية الغربية
Christianity in the Middle Ages covers the history of Christianity from the Fall of the Western Roman Empire (). The end of the period is variously defined. Depending on the context, events such as the conquest of Constantinople by the Ottoman Empire in 1453, Christopher Columbus's first voyage to the Americas in 1492, or the Protestant Reformation in 1517 are sometimes used.
