The medieval era, often called The Middle Ages or the Dark Ages, began around 476 A.D. following a great loss of power throughout Europe by the Roman Emperor.
The Middle Ages span roughly 1,000 years, ending between 1400 and 1450. In Spain, however, 1492 is considered the end of their medieval period and the beginning of the modern era.The period was one of human expansion, centralization and great political upheaval and violence, resulting in the foundation of many modern European countries. It was also dominated by a surge in Christianity leading to the building of great cathedrals, clearing of large tracts of land by peasants, settling of new towns and villages, and building of great castles by local nobility.
