Intellectual revival of Europe in 13th, 14th and 15th century.

Middle Ages, the period in the history of Europe that lasted from about AD 350 to about 1450.By the end of the Middle Ages, many modern European states had taken shape. The term middle ages was invented by people during the Renaissance, a period of cultural and literary change in the 13, 14 and 15th centuries. During the Renaissance, people thought that their own age and the time of ancient Greece and Rome were advanced, sophisticated, enlightened and civilized. The adjective medieval comes from the Latin words for this term, medium (middle) and aevum (age).
The word medieval is often used today to mean barbaric, ignorant, and backward. It is true that some aspects of the middle Ages horrify many people today the ideas of heretics being burned at the stake, mercenary armies on the rampage, and plagues for which there are no cures are not pleasant ones.
Although the period is often portrayed negatively, the middle ages were a time when the precursor and herald of many important modern institutions were created. Medieval universities are the direct ancestors of modern ones. The liberal arts of the middle ages remain the core of the arts and sciences programs of today’s college. The English Parliament that met in London yesterday can trace its origins to the days of Henry III.
Similarly, modern cities grew out of medieval ones. Although ancient cities had existed before the middle Ages, they had been centers of political and religious life, not centers of commerce. Medieval cities, in contrast, were primarily commercial. They were supported by trade, exchange, production, consumption, and moneymaking. Many of the sorts of businesses that exist today, such as banks and corporations, can map out their ancestry to the middle ages.
Even nationalism began in the middle ages, as was demonstrated by the hundred years’ war and Joan of Arc. The age was the period in which different groups Romans, Franks, and Visigoths intermingle, fought, worked together and changed. Medieval social, economic, and artistic transformation both reflected and provoked creative responses and accommodations. The history of the middle ages (13, 14 and 15th century) is a story of ceaseless borrowing, adaptation and change with the aggrandizement in various pre-requisite of development.
