The first de factoLord (Italian:Signore) in the history of theRepublic of Florence wasCosimo de' Medici. Thanks to his moderate policy, Cosimo managed to maintain power for over thirty years until his death, ruling the state silently through his trusted men and thus allowing the consolidation of his family, theMedici, in the government of Florence.[1]
In 1532, to reinforce and formalize the Medici rule in Florence,Pope Clement VII, himself a Medici, created the title ofDuke of the Florentine Republic toAlessandro de' Medici. With the creation of the new title it abolished the age-oldsignoria (elective government) and the office ofgonfaloniere (titular head-of-state elected for a two-month term) and replaced it with three institutions: theconsigliere, the Senate and the Council of Two Hundred.[2][3]
From its creation in the 12th century until the first decades of the 15th century, the city-state ofFlorence was ruled by a series of democratic governments, such as theConsul,Podestà and most notably by a council known as theSignoria of Florence. The signoria was chosen by thegonfaloniere (titular ruler of the city), who was elected every two months byFlorentine guild members. Not having until that moment fallen into the hands of powerful dynasties as happened in several otherItalian states.[4] This situation completely changed with the rise of the Medici family, in that period owners of the largest European bank, and the wealthiest family of that era, which made the dynasty accumulate immense influence in the city, even without holding public offices.[5][6][7]
