Amalfi is first mentioned in the 6th century, and soon acquired importance as a naval power. In the 9th century it shared with Venice and Gaeta the Italian trade with the East, and in 848 its fleet went to the assistance of Pope Leo IV against the Saracens.
It was then an independent republic with a population of some 70,000, but in 1131 it was reduced by King Roger II of Sicily. In 1135 and 1137 it was taken by the Pisans, and rapidly declined in importance, though its maritime code, known as the Tavole Amalfitane, was recognized in the Mediterranean until 1570. In 1343 a large part of the town was destroyed by an inundation, and its harbor is now of little importance.
Amalfi is the main town of the coast on which it is located, named Costiera Amalfitana, and is today an important touristic destination together with other towns on the same coast, such as Positano, Sorrento, and others.
