Lehel, a member of the Árpád dynasty, was a Magyar chieftain and, together with Bulcsú, one of the most important figures of the Hungarian invasions of Europe. After the Magyar defeat at the Battle of Lechfeld, he was executed in Regensburg.

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.
