Italian city-states
With the establishment of the medieval towns, Italian city-states and maritime republics, the patriciate was a formally-defined social class of governing wealthy families. They were found in the Italian city-states and maritime republics, particularly in Venice, Genoa, Pisa and Amalfi. They were also found in many of the free imperial cities of the Holy Roman Empire, such as Nuremberg, Ravensburg, Augsburg, Konstanz, Lindau, Bern, Basel, Zurich and many more.
