The Republic of Florence, officially the Florentine Republic (Italian: Repubblica Fiorentina, pronounced [reˈpubblika fjorenˈtiːna], or Repubblica di Firenze), was a medieval and early modern state that was centered on the Italian city of Florence in Tuscany. 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.
