Duchy of Amalfi

The Duchy of Amalfi (Italian: Ducato di Amalfi) or the Republic of Amalfi (Italian: Repubblica di Amalfi) was a de facto independent state centred 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. It rose to become an economic powerhouse, a commercial centre whose merchants dominated Mediterranean and Italian trade for a century before being surpassed and superseded by the other maritime republics of the North, like Pisa, Venice, and Genoa. In 1073, Amalfi lost its independence and fell to the Normans of the Principate of Salerno, from whose yoke it failed in two separate attempts to free itself.
