Lothair I is crowned King of Italy by Pope Paschal I.

Lothair I was a 9th-century emperor of the Carolingian empire and king of Italy (818–855) and Middle Francia (843–855).

King of Italy was the title given to the ruler of the Kingdom of Italy after the fall of the Western Roman Empire. The first to take the title was Odoacer, a barbarian warlord, in the late 5th century, followed by the Ostrogothic kings up to the mid-6th century. With the Frankish conquest of Italy in the 8th century, the Carolingians assumed the title, which was maintained by subsequent Holy Roman Emperors throughout the Middle Ages. The last Emperor to claim the title was Charles V in the 16th century. During this period, the holders of the title were crowned with the Iron Crown of Lombardy.

Pope Paschal I was the bishop of Rome and ruler of the Papal States from 25 January 817 to his death in 824.
