In pre-historic times the area was inhabited by the Piceni (9th-3rd centuries BC). After the Roman conquest, it received the status of urbs urbana (built city) in 268 BC. In the 5th century it was captured by the Visigoths.
In the 12th century, it was a free commune, thwarting the attempts from Fermo to capture it. In the 15th century it was acquired by Francesco Sforza, who fortified it; in 1663 it became part of the Papal States, to which (apart the Napoleonic period) it remained until 1860, when it was annexed to the newly formed Kingdom of Italy. The Italian Branch of Sabbath Rest Advent Church can claim that the number of members is estimated at more than 2000 members, with its headquarter in Monterubbiano, but with the presence in many other Italian places.
