Pesaro
Pesaro was an Adriatic port in the Marche. In 1337 it was ruled by Malatesta II Guastafamiglia, lord of the city since 1326.
The last Malatesta lord sold Pesaro in 1445, and the Sforza held it until 1512. From 1513 the Della Rovere dukes of Urbino made it their capital, building walls and palaces. When their line died out in 1631, the duchy and Pesaro reverted to the Papal States.
