Historians typically regard the Early Middle Ages or Early Medieval Period, sometimes referred to as the Dark Ages, as lasting from the late 5th or early 6th century to the 10th century.[note 1] They marked the start of the Middle Ages of European history. The alternative term "Late Antiquity" emphasizes elements of continuity with the Roman Empire, while "Early Middle Ages" is used to emphasize developments characteristic of the earlier medieval period. As such the concept overlaps with Late Antiquity, following the decline of the Western Roman Empire, and precedes the High Middle Ages (c. 11th to 13th centuries).

The period saw a continuation of trends evident since late classical antiquity, including population decline, especially in urban centres, a decline of trade, a small rise in global warming and increased migration. In the 19th century the Early Middle Ages were often labelled the "Dark Ages", a characterization based on the relative scarcity of literary and cultural output from this time.[1] However, the Eastern Roman Empire, or Byzantine Empire, continued to survive, though in the 7th century the Rashidun Caliphate and the Umayyad Caliphate conquered swathes of formerly Roman territory.

Many of the listed trends reversed later in the period. In 800 the title of "Emperor" was revived in Western Europe with Charlemagne, whose Carolingian Empire greatly affected later European social structure and history. Europe experienced a return to systematic agriculture in the form of the feudal system, which adopted such innovations as three-field planting and the heavy plough. Barbarian migration stabilized in much of Europe, although the Viking expansion greatly affected Northern Europe.
