Abruzzi was conquered by the Romans in 400 BC. Many traces of the Romans are still visible today in the archaeological area around Avezzano, including the ruins of the amphitheatre in Amiternum, the remains of the town of Alba Fucens, which is still being excavated, and in Chieti.
Later Abruzzi was incorporated into the Lombard duchy of Spoleto. The Lombards' rule ceased when the Norman kingdom of Sicily consolidated its powers in this part of Italy. Following this period, the kingdom of Naples ruled Abruzzi for more than 600 years.
