The Carolingian Empire (800–888) was a large empire in western and central Europe during the early Middle Ages. It was ruled by the Carolingian dynasty, which had ruled as kings of the Franks since 751 and as kings of the Lombards of Italy from 774. In 800, the Frankish king Charlemagne was crowned emperor in Rome by Pope Leo III in an effort to revive the Roman Empire in the west during a vacancy in the throne of the eastern Roman Empire. After a civil war (840–43) following the death of Emperor Louis the Pious, the empire was divided into autonomous kingdoms, with one king still recognised as emperor, but with little authority outside his own kingdom. The unity of the empire and the hereditary right of the Carolingians continued to be acknowledged.

In 884, Charles the Fat reunited all the kingdoms for the last time, but he died in 888 and the empire immediately split up. With the only remaining legitimate male of the dynasty a child, the nobility elected regional kings from outside the dynasty or, in the case of the eastern kingdom, an illegitimate Carolingian. The illegitimate line continued to rule in the east until 911, while in the western kingdom the legitimate Carolingian dynasty was restored in 898 and ruled until 987 with an interruption from 922 to 936.

The size of the empire at its inception was around 1,112,000 square kilometres (429,000 sq mi), with a population of between 10 and 20 million people. To the south it bordered the Emirate of Córdoba and, after 824, the Kingdom of Pamplona; to the north it bordered the kingdom of the Danes; to the west it had a short land border with Brittany, which was later reduced to a tributary; and to the east it had a long border with the Slavs and the Avars, who were defeated and their land incorporated into the empire. In southern Italy, the Carolingians' claims to authority were disputed by the Byzantines (eastern Romans) and the vestiges of the Lombard kingdom in the Principality of Benevento.
