Duchy of Amalfi

The Duchy of Amalfi or the Republic of Amalfi was a de facto independent state centered on the Southern Italian city of Amalfi during the 10th and 11th centuries. The city and its territory were originally part of the larger ducatus Neapolitanus, governed by a patrician, but it extracted itself from Byzantine vassalage and first elected a duke in 958. During the 10th and 11th centuries Amalfi was estimated to have a population of 50,000 -70,000 people. It rose to become an economic powerhouse, a commercial center whose merchants dominated Mediterranean and Italian trade for centuries before being surpassed and superseded by the other maritime republics of the North, like Pisa, Venice, and Genoa. In 1073, Amalfi lost its independence, falling to French Norman invasion and subsequently to Pisa in 1137.

The city of Amalfi was founded as a trading post in 339. Its first bishop was appointed in 596. In 838, the city was captured by Sicard of Benevento with help from traitors within the city, who led him in through the waterward defenses. Many of the Amalfitans in Salerno sacked that city and left. In 839, Amalfi freed itself from Lombard domination and elected a prefect. Nearby Atrani participated in these early prefectural elections. Subsequently, Amalfi helped to free Siconulf to oppose the ruling Prince of Benevento. In 897, the self-governing republic, still nominally tied to the Byzantine Empire, was defeated in a war with Sorrento, supported by Naples, in which her prefect was captured, later ransomed. In 914, the prefect Mastalus I was appointed first judge. In 903 the Amalfitans joined forces with Naples to attack the Arabs that had established them selves on the banks of the Garigliano river. However the combined forces of Amalfi and the Naples were driven back by the Arabs and their allies, the Italian city state of Gaeta. In 915 Amalfi did not join the Battle of Garigliano to fight against the Arabs. This was most likely due to the fact that since 909 Amalfi had been heavily trading with the Fatimid Caliphate and did not want to jeopardize relations with this powerful trade partner. In 958, Mastalus II was assassinated and Sergius I was elected first duke . From 981 to 983, Amalfi ruled the Principality of Salerno. In 987, the Amalfitan bishopric was raised to archiepiscopal status.
