Potestate

Podestà (pronounced [podeˈsta]) is the name given to certain high officials in many Italian cities beginning in the later Middle Ages. Mainly 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"), but it could also mean the local administrator, who was the representative of the Holy Roman Emperor. Currently, Podestà is the title of mayors in Italian-speaking municipalities of Graubünden in Switzerland.

The term derives from the Latin word potestas, meaning power. There is a similar derivation for the Arabic term Sultan: originally meaning "power" or "authority", it eventually became the title of the person holding power.

The first documented usage of podestà was in Bologna in 1151, when it was applied to Guido di Ranieri di Sasso of Canossa, brought in from Faenza to be rettore e podestà, noted in numerous documents.Leander Albertus gives the particulars:

"The citizens, seeing that there often arose among them quarrels and altercations, whether from favoritism or friendship, from envy or hatred that one had against another, by which their republic suffered great harm, loss and detriment; therefore, they decided, after much deliberation, to provide against these disorders. And thus they began to create a man of foreign birth their chief magistrate, giving him every power, authority and jurisdiction over the city, as well over criminal as over civil causes, and in times of war as well as in times of peace, calling him praetor as being above the others, or podestà., as having every authority and power over the city."

Podestàs were first more widely appointed by the Holy Roman Emperor Frederick Barbarossa when he began to assert the rights that his Imperial position gave him over the cities of northern Italy; at the second imperial diet at Roncaglia, November 1158, Frederick appointed in several major cities imperial podestàs "as if having imperial power in that place" The elected consuls, which Frederick had claimed the right to ratify, he began to designate directly. The business of the podestà was to enforce imperial rights. From the start, this was very unpopular, and their often arbitrary behaviour was a factor in bringing about the formation of the Lombard League and the uprising against Frederick in 1167.
