[1] It was created in the early 13th century when the populares, the increasingly wealthy classes of commoners (merchants, professionals, craftsmen and, in maritime cities, ship-owners) began to acquire roles in the communal administration of various Italian city-states, and needed a municipal officeholder able to counter the political power of the nobles (called potentes), represented usually by the podestà (a title used for chief magistrates and other top administrators in medieval Italian cities).
The capitano del popolo exercised control of the podestà, sometimes flanked by two autonomous councils with representatives of local guilds of artisans and craftsmen (Italian: arti e mestieri) and the gonfalonieri, leaders of military units connected with city's parishes.
In the Republic of Florence, a capitano del popolo existed from 1250 as part of the attempt to free the city from the rule of Frederick II.
[clarification needed] Such office also existed in the early stages of the Republic of Genoa, that elected Guglielmo Boccanegra as its first capitano del popolo in 1257.
Towards the second half of the 13th century, however, the communal title of capitano del popolo became a breeding ground for despotism and hereditary lordship.
