The Hungarian invasions of Europe took place in the 9th and 10th centuries, the period of transition in the history of Europe in the Early Middle Ages, when the territory of the former Carolingian Empire was threatened by invasion from multiple hostile forces, the Magyars (Hungarians) from the east, the Viking expansion from the north, and the Arabs from the south.

Hungarians, also known as Magyars, are a Central European nation and an ethnic group native to Hungary and historical Hungarian lands who share a common culture, history, ancestry, and language. The Hungarian language belongs to the Uralic language family, alongside, most notably Finnish and Estonian.
