In 272 B.C. the province was conquered by the Greek army. The new rulers renamed Basilicata as Lucania. Later in the 11th century, the area became part of the Duchy of Apulia, which was at the time ruled by the Normans. From the 13th century it was part of the Kingdom of Naples, though Potenza was actually ruled by local feudataries. In 1861 the province was unified with the rest of Italy in the newly formed Kingdom of Italy.
