Ermengarde, queen of the Franks

Ermengarde of Hesbaye, probably a member of the Robertian dynasty, was Carolingian empress from 813 and Queen of the Franks from 814 until her death as the wife of the Carolingian emperor Louis the Pious.

The Kingdom of the Franks, also known as the Frankish Kingdom, or just Francia, was the largest post-Roman kingdom in Western Europe. It was established by the Franks, one of the Germanic peoples. Its founder was king Clovis I (481–509), who united Frankish tribes, and expanded the Frankish realm into the Roman Gaul. During the Early Middle Ages, the Kingdom was ruled by the Merovingian and Carolingian dynasties. In 800, it evolved into the Carolingian Empire, thus becoming the longest lasting Germanic kingdom from the era of Great Migrations.
