The Middle Ages of European history (adjective form mediaeval or medieval) are a period in history which lasted for roughly a millennium, commonly dated from the fall of the Western Roman Empire in the 5th century to the beginning of the Early Modern Period in the 16th century, marked by the division of Western Christianity in the Reformation, the rise of humanism in the Italian Renaissance, and the beginnings of European overseas expansion. There is some variation in the dating of the edges of these periods which is due mainly to differences in specialization and focus of individual scholars.
