The first Roman republican wars were wars of both expansion and defence, aimed at protecting Rome itself from neighbouring cities and nations and establishing its territory in the region. Initially, Rome's immediate neighbours were either Latin towns and villages, or else tribal Sabines from the Apennine hills beyond. One by one Rome defeated both the persistent Sabines and the local cities, both those under Etruscan control and those that had cast off their Etruscan rulers. Rome defeated Latin cities in the Battle of Lake Regillus in 496 BC, the Battle of Mons Algidus in 458 BC, the Battle of Corbione in 446 BC, the Battle of Aricia, and especially the Battle of the Cremera in 477 BC wherein it fought against the most important Etruscan city of Veii.
