Guido II da Montefeltro
Guido II da Montefeltro, known as Novello, was a Ghibelline condottiero and count of Urbino, son of Count Federico I. When his father was killed in the Urbino revolt of 26 April 1322, he took refuge in Gubbio; in 1323 he returned to Urbino after two years of papal rule.
He ruled as count of Urbino from 1324 to 1360 and in 1341 served the Florentines against Lucca. He married Gentile Brancaleoni, who bore him no children.
