The importance of Umbria in Roman and medieval times was intimately bound up with the Via Flaminia, the consular road that supplied Rome and served as a military highway into and out of the City: for this reason once the Roman empire collapsed, Umbria became a strategic battleground fought over by the Church, the Lombards and the Byzantines, and suffered consequently, becoming partitioned among them and disappearing from history. The modern use of "Umbria" is due to a renaissance of local identity in the 17th century.
