It became an Augustan colony and after the 476 fall of Rome, it joined a Byzantine confederation containing a number of cities along the coast of Marche. Following this, it was under papal rule for many years until it became a commune in the eleventh century. It was ruled by the family of Guelph Malatesta until the sixteenth century, when it was briefly ruled by the Republic of Venice. It became part of the Papal States and later became a component of the kingdom of Italy. In World War II, it was heavily bombed but liberated in 1944 by British and Polish troops.
