them Claudius and Tiberius, the latter of whom is infamously linked to the island of Capri. It was also during this period that Christianity came to Campania. Two of the apostles, St. Peter and St. Paul, are said to have preached in the city of Naples, and there were also several martyrs during this time. Unfortunately, the period of relative calm was violently interrupted by the epic eruption of Mount Vesuvius in 79 which buried the cities of Pompeii and Herculaneum. With the Decline of the Roman Empire, its last emperor, Romulus Augustus, was put in a manor house prison near Castel dell'Ovo, Naples, in 476, ushering in the beginning of the Middle Ages and a period of uncertainty in regard to the future of the area. Feudalism in the Middle Ages The area had many duchies and principalities during the Middle Ages, in the hands of the Byzantine Empire (also referred to as the Eastern Roman Empire) and the Lombards. Under the Normans, the smaller independent states were brought together as part of the Kingdom of Sicily, before the mainland broke away to form the Kingdom of Naples. It was during this period that elements of Spanish, French and Aragonese culture were introduced to Campania. Allegiances with the Muslim Saracens were made in 836, and the Arabs were requested to repel the siege of Lombard troops coming from the neighbouring Duchy of Benevento. The Kingdom Norman to Angevin After a period as a Norman kingdom, the Kingdom of Sicily passed to the Hohenstaufens, who were a powerful Germanic royal house of Swabian origins. The University of Naples Federico II was founded by Frederick II in the city, the oldest state university in the world, making Naples the intellectual centre of the kingdom. Conflict between the Hohenstaufen house and the Papacy, led in 1266 to Pope Innocent IV crowning Angevin Dynasty duke Charles I as the king. Charles officially moved the capital from Palermo to Naples where he resided at the Castel Nuovo. During this period, much Gothic architecture sprang up around Naples, including the Naples Cathedral, the main church of the city. In 1281, with the advent of the Sicilian Vespers, the kingdom split in half. The Angevin Kingdom of Naples included the southern part of the Italian peninsula, while the island of Sicily became the Aragonese Kingdom of Sicily. The wars continued until the peace of Caltabellotta in
