The 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, the term used for the banners of such communes.
In Florence the office was known as Gonfaloniere of Justice and was held by one of the nine citizens selected by the drawing lots every two months, who formed the city's government, or Signoria. In the papal states it was known as Gonfaloniere of the Church or Papal Gonfaloniere. Other central and northern Italian communes, from Spoleto to the County of Savoy, elected or appointed gonfalonieri. The Bentivoglio family of Bologna aspired to this office during the sixteenth century. However, by the year 1622, when Artemisia Gentileschi painted a portrait of Pietro Gentile as a gonfaloniere of Bologna, with the gonfalone in the background, the office had merely symbolic value.
Gonfaloniere of Justice (Gonfaloniere di Giustizia) was a post in the government of medieval and early Renaissance Florence. Like Florence's Priori, it was introduced in 1293 when Giano Della Bella's Ordinamenti di Giustizia came into force.
He was one of the nine citizens selected by drawing lots every two months, who formed the government, or Signoria. As Gonfaloniere di Giustizia he was the temporary standard-bearer of the Republic of Florence and custodian of the city's banner, which was displayed from the yardarm of a portable cross. Along with the voting rights of the other Priori, he was also in charge of the internal security forces and the maintenance of public order. To distinguish him from his other eight colleagues, his crimson coat, lined with ermine, was further embroidered with golden stars. Each of Florence's neighborhoods, or rioni, had its own priore who might be selected to serve on the council, and its own gonfaloniere di compagnia selected from the first families of each quarter.
