Louis II of Italy in the context of "Carloman of Bavaria"

The province of Matera (Italian: provincia di Matera; Materano: provìngë dë Matàërë) is a province in the Basilicata region of Italy. Its capital is the city of Matera. It has an area of 3,447 square kilometres (1,331 sq mi) and a total population of 201,133; the city of Matera has a population of 61,204. The province contains 31 comuni (sg.: comune), listed in the list of comuni of the province of Matera). It is bordered by the province of Potenza in the west and south, the region of Calabria also to the south, the region of Apulia to the east and north, and by the Ionian Sea to the southeast.

The history of settlement in the region dates back to the Palaeolithic Period and the first instance of organised settlement was in 251 BCE, when Roman Republic consul Lucius Caecilius Metellus founded the town as Matera. Matera was sacked multiple times; initially by the Franks, then by Roman Emperor Louis II of Italy, and then by invading Muslims during the 10th century. Following this, the town was owned by the Capetian House of Anjou and the Crown of Aragon and was sold multiple times to successive wealthy families.

Basil I, nicknamed "the Macedonian" (Greek: Βασίλειος ὁ Μακεδών, romanized: Basíleios ō Makedṓn; 811 – 29 August 886), was Byzantine emperor from 867 to 886. Born to a peasant family in Macedonia, he rose to prominence in the imperial court after gaining the favour of Emperor Michael III, whose mistress he married on his emperor's orders. In 866, Michael proclaimed him co-emperor. Fearing a loss of influence, Basil orchestrated Michael's assassination the next year and installed himself as sole ruler of the empire. He was the first ruler of the Macedonian dynasty.

Despite his humble origins, Basil was an effective and respected monarch. He initiated a complete overhaul of Byzantine law, an effort continued by his successor that ultimately became the Basilika. On the foreign front, he achieved military success against the heretical Paulicians, whom he subjugated in 872. He also pursued an active policy in the west, allying with Carolingian emperor Louis II against the Arabs, which led to a new period of Byzantine domination in Italy. Upon his death in a hunting accident in 886, he was succeeded by his son Leo VI, also rumoured to have been the son of Michael III.

The Frankish emperor Louis II campaigned against the Emirate of Bari continuously from 866 until 871. Louis was allied with the Lombard principalities of southern Italy from the start, but an attempt at joint action with the Byzantine Empire failed in 869. In the final siege of the city of Bari in 871, Louis was assisted by a Slavic fleet from across the Adriatic.

The city fell and the emir was taken captive, bringing the emirate to an end, but a Saracen presence remained at Taranto. Louis himself was betrayed by his Lombard allies six months after his victory and had to leave southern Italy.
