The Kings of the Lombards (, singular "") ruled that Germanic people from their invasion of Italy in 567–68 until the Lombardic identity became lost in the ninth and tenth centuries. After 568, the Lombard kings sometimes styled themselves Kings of Italy (). Upon the Lombard defeat at the 774 Siege of Pavia, the kingdom came under the Frankish domination of Charlemagne. The Iron Crown of Lombardy ("Corona Ferrea") was used for the coronation of the Lombard kings, and the kings of Italy thereafter, for centuries.
