Berengar I

Berengar I., son of Eberhardt, Duke of Friuli, caused himself to be proclaimed king of Italy in 888, and, getting rid of his many rivals, was elected emperor in 915. In 923 his nobles, fearing his encroachments, supported Rudolph II. of Burgundy in usurping the throne, and Berengar was thrown into prison at Verona and was killed in 924.
