The High Middle Ages or High Medieval Period was the period of European history around the 11th, 12th, and 13th centuries (c. 1001–1300). The High Middle Ages were preceded by the Early Middle Ages and followed by the Late Middle Ages, which by convention end around 1500.

The key historical trend of the High Middle Ages was the rapidly increasing population of Europe, which brought about great social and political change from the preceding era, the Renaissance of the 12th century, including the first developments of rural exodus and urbanization. By 1250 the robust population increase greatly benefited the European economy, reaching levels that would not be seen again in some areas until the 19th century. This trend was checked in the Late Middle Ages by a series of calamities, notably the Black Death but also including numerous wars and economic stagnation.

From about the year 780 onwards, Europe saw the last of the barbarian invasions and became more socially and politically organized. The Carolingian Renaissance led to scientific and philosophical revival of Europe. The first universities were established in Bologna, Paris, Oxford and Modena. The Vikings had settled in the British Isles, France and elsewhere, whilst Norse Christian kingdoms were developing in their Scandinavian homelands. The Magyars had ceased their expansion in the 10th century, and by the year 1000, a Christian Kingdom of Hungary was recognized in Central Europe, forming alliances with regional powers. With the brief exception of the Mongol invasions in the 13th century, major nomadic incursions ceased. The powerful Byzantine Empire of the Macedonian and Komnenos dynasties gradually gave way to the resurrected Serbia and Bulgaria and to a successor Crusader state from 1204 to 1261, while countering the continuous threat of the Seljuk Turks in Asia Minor.
