Lambert II of Spoleto, Holy Roman Emperor Holy Roman Emperor
Lambert II (c. 880 – 15 October 898) was the King of Italy from 891, Holy Roman Emperor, co-ruling with his father from 892, and Duke of Spoleto and Camerino from his father's death in 894. He was the son of Guy III of Spoleto and Ageltrude, born in San Rufino. He was the last ruler to issue a capitulary in the Carolingian tradition. Lambert was crowned King in May 891 at Pavia and joint Emperor alongside his father on 30 April 892 at Ravenna by a reluctant Pope Formosus. He and his father signed a pact with the pontiff confirming the Donation of Pepin and subsequent Carolingian gifts to the papacy. In 893, however, Formosus sent an embassy to Regensburg to request Arnulf of Carinthia liberate Italy and come to Rome to be crowned. Arnulf sent his son Zwentibold with a Bavarian army to join with Berengar of Friuli. They defeated Guy, but bribes, along with an outbreak of fever, saw him leave in the autumn. Arnulf then personally led an army across the Alps early in 894. He conquered all of the territory north of the Po River, but went no further before Guy died suddenly in late autumn. Lambert became sole king and emperor, as well as succeeded his father to the Duchy of Spoleto.
