Treaty of Florence (1844)

The Treaty of Florence, signed on 28 November 1844, was a secret agreement between the governments of the Grand Duchy of Tuscany, the Duchy of Modena and Reggio, and Charles Louis of Bourbon-Parma, Duke of Lucca and future Duke of Parma, Piacenza, and Guastalla. The treaty aimed to update the territorial provisions and compensations established by the Congress of Vienna in 1815, while rationalizing borders among the involved states in the regions of Lunigiana, Garfagnana, the coast facing the Apuan Alps, and along the Enza River in Emilia.
