Italian city-states

The Republic of Venice, officially the Most Serene Republic of Venice and traditionally known as La Serenìssima, was a sovereign state and maritime republic with its capital in Venice. Founded, according to tradition, in 697 by Paolo Lucio Anafesto, over the course of its 1,100 years of history it established itself as one of the major European commercial and naval powers. Initially extended in the Dogado area (a territory currently comparable to the Metropolitan City of Venice), during its history it annexed a large part of Northeast Italy, Istria, Dalmatia, the coasts of present-day Montenegro and Albania as well as numerous islands in the Adriatic and eastern Ionian seas. At the height of its expansion, between the 13th and 16th centuries, it also governed the Peloponnese, Crete and Cyprus, most of the Greek islands, as well as several cities and ports in the eastern Mediterranean.

The Free Municipality of Sassari or Republic of Sassari was a state in the region of Sassari in Sardinia during the 13th and 14th centuries, confederated first with the Republic of Pisa as a semi-autonomous subject and later with the Republic of Genoa as a nominally independent ally. It was the first and only independent city-state of Sardinia during the early renaissance.

The Duchy of Parma and Piacenza (Italian: Ducato di Parma e Piacenza, Latin: Ducatus Parmae et Placentiae) was an Italian state created in 1545 and located in northern Italy, in the current region of Emilia-Romagna.

The Duchy of Milan (Italian: Ducato di Milano; Lombard: Ducaa de Milan) was a state in Northern Italy, created in 1395 by Gian Galeazzo Visconti, then the lord of Milan, and a member of the important Visconti family, which had been ruling the city since 1277.

The Republic of Florence (Latin: Res publica Florentina; Old Italian: Republica di Fiorenza), known officially as the Florentine Republic, was a medieval and early modern state that was centered on the Italian city of Florence in Tuscany, Italy. The republic originated in 1115, when the Florentine people rebelled against the Margraviate of Tuscany upon the death of Matilda of Tuscany, who controlled vast territories that included Florence. The Florentines formed a commune in her successors' place. The republic was ruled by a council known as the Signoria of Florence. The signoria was chosen by the gonfaloniere (titular ruler of the city), who was elected every two months by Florentine guild members.

The Italian city-states were numerous political and independent territorial entities that existed in the Italian Peninsula from antiquity to the formation of the Kingdom of Italy in the late 19th century.

The Gonfalonier (Italian: Gonfaloniere) was the holder of a highly prestigious communal office in medieval and Renaissance Italy, notably in Florence and the Papal States. The name derives from gonfalone (English: "gonfalon"), the term used for the banners of such communes.

Podestà, also potestate or podesta in English, was the name given to the holder of the highest civil office in the government of the cities of central and northern Italy during the Late Middle Ages. Sometimes, it meant the chief magistrate of a city-state, the counterpart to similar positions in other cities that went by other names, e.g. rettori ('rectors').

The Duchy of Friuli (Latin: Ducatus Foroiuliensis) was a Lombard duchy in present-day Friuli, the first to be established after the conquest of the Italian peninsula in 568. It was one of the largest domains in Langobardia Major and an important buffer between the Lombard kingdom and the Slavs, Avars, and the Byzantine Empire. The original chief city in the province was Roman Aquileia, but the Lombard capital of Friuli was Forum Julii, modern Cividale.

The Republic of Siena (Italian: Repubblica di Siena, Latin: Respublica Senensis) was a historic state consisting of the city of Siena and its surrounding territory in Tuscany, Central Italy. It existed for over 400 years, from 1125 to 1555. During its existence, it gradually expanded throughout southern Tuscany and became one of the major economic powers of the Middle Ages. It was one of the most important commercial, financial and artistic centers in Europe.
