Duke of Amalfi
The medieval Republic of Amalfi was ruled, in the tenth and eleventh centuries, by a series of dukes (Latin: duces), sometimes called dogi (singular doge) in analogy to the Republic of Venice, a maritime rival of the time. Before the dukeship was officially created in 957, there was a series of patricians. The Amalfitan duchy was one of the earliest maritime republics renowned throughout the Mediterranean, a trading city rivalling the cities of the north.

Norman domination 
Amalfi was conquered by Robert Guiscard, duke of Apulia. At some point, his son Guy was made duke. Nevertheless, Amalfi rebelled twice, once electing the former prince of Salerno, Gisulf, and once electing a Neapolitan of that ducal family.
A certain Manso was ruling in Amalfi—and minting his own coins there—with the title of vicedux (viceduke) sometime between 1077 and 1096, most probably during the reign of Robert's son Roger Borsa. Manso recognised Norman overlordship and was probably a Norman appointee.
