The Middle Ages are a time period in Europeanhistory. They started around the year 476 CE when the Western Roman Empire ended, and continued until around the time Christopher Columbus discovered the New World in 1492. The 'Middle Ages' are called this because it is the time between the fall of Imperial Rome and the beginning of the Early modern Europe. This period of time is also known as the Medieval Age, the Dark Ages (due to the lost technology of the Roman empire), or the Age of Faith (because of the rise of Christianity and Islam). When used narrowly, the term "Dark Ages" refer only to very early period, from 476 to 800 (when Charlemagne became king).
The fall of the Roman Empire, and the invasions of barbarian tribes, devastated European towns and cities and their inhabitants. The Dark Ages are given this name because Europe was in disarray in comparison to the orderliness of classical antiquity and life was short and poor. Since few could write, little is known about it. Much of the knowledge that the Romans used (science, technology, medicine, and literature) was lost. The Dark Ages period was marked by mass migrations, wars and plagues. This lasted some 300 years until the development of feudalism partly diminished the continuous violence. Emperor Charlemagne was crowned in 800, and he promoted order, education and civilization. Europe began slowly regain what was lost during those centuries.
The siege of Constantinople is shown in a 15th-century manuscript (Chronique de Charles VII)
Meanwhile, the remains of Eastern Rome had become the Byzantine Empire, which was started by Roman emperor Constantine in 330, and likewise had a capital city named Constantinople. The Byzantine empire controlled Asia Minor and Northern Africa, and sometimes Southern Spain and southern Italy, but its lands were slowly eaten away by enemies like the Turks and the Franks.
