Federico I da Montefeltro

Federico I da Montefeltro (c. 1250–1322) was a Ghibelline condottiere and count of Urbino, eldest son of Guido I. As podestà of Arezzo he defeated the Guelphs of Florence and Siena at Cennina in 1303, and in 1305 formed the League of the Friends of the March.

He defeated the Malatesta in 1307 and conquered Ancona as podestà of Pisa in 1309; in 1310 Emperor Henry VII named him captain-general of the imperial army's Italian troops. He retook Urbino and Fano from the papalists in 1317, but in a popular revolt in Urbino he surrendered and begged for mercy, and he and his son Guido were killed on 26 April 1322.
