The Marquessate of Groppoli, in Tuscany and Liguria, was ruled by the House of Brignole-Sale, an illustrious patrician family of Genoa who were its sovereigns from 1592 to 1774.
It was originally an imperial fief, part of the former lands of the Malaspina di Mulazzo family, and later became a fief of the Grand Duchy of Tuscany.
The commune covered an area of 12 km². It was inhabited by 131 families and had a total population of 712 in 1833.
The Marquessate of Groppoli
Due to its strategic, military and commercial position, the Marquessate served as a hinge between Liguria, Lombardy and Tuscany. As such the Republic of Genoa and the Medici family competed to extend their dominance over the region. In the medieval period Groppoli formed a part of the lands held by the Malaspina family. The imperial fief of Groppoli was acquired by Count Landi of Piacenza, as the inheritance of his wife Briseide, daughter of Azzone Malaspina, and in 1549 Landi sold it to Cosimo I de' Medici. After a five-year dispute in the Imperial Aulic Council it returned to the hands of Giovan Cristoforo Malaspina. In 1576 it became autonomous again as a result of the division between the brothers Antonio Maria, Octavian, Giovanni Gaspar and Caesar, sons of Giovan Cristoforo Malaspina. But the fief did not remain in the hands of Antonio Maria for long and in March 1577 he sold it for 21,000 scudi to Francesco I de' Medici, who received the imperial investiture the following year.
On 4 July 1592 Ferdinando I de' Medici granted the marquessate to Giulio Cibo Sale for 'the sincere devotion shown on several occasions to the Florentine court' and a payment of 30,000 scudi in gold. Giulio was installed in the fief, which included the castle and the surrounding territory, which could be inherited by males and females, provided that the marquisate was kept undivided. The new feudal lord was granted the rights and privileges of hunting, fishing, gabelle, tolls, mills, etc., but was forbidden from granting pardons and making a military levy.
Giulio's only daughter and heiress Geronima married into the Brignole family and in 1607 the lands and title passed to her two-year-old son Anton Giulio, who took the name Brignole-Sale.
The Marquessate was governed at a distance and ruled by the functionaries of the Brignole-Sale family who sometimes abused their powers, especially in the early 18th century.
The Marquessate was in effect independent and entered into the orbit of the Republic of Genoa. It was occupied from 1746 to 1748 by the Austrians, while Gian Francesco II Brignole-Sale was Doge of Genoa. In 1749, the Doge Gian Francesco II Brignole Sale, breaking with the policy of his predecessors, decided to directly administer his lands and dispense justice himself in an attempt to detach the Marquessate by refusing to apply the laws of the Grand Duchy of Tuscany. At his death in 1760, his brother Rodolfo II Brignole-Sale inherited the Marquessate and from then on the Grand Duchy of Tuscany unceasingly attempted to recover Groppoli.
In 1773, the people of Groppoli, unhappy with the fiscal policies of the Brignole-Sale family, revolted and besieged the 15th century castle.
In 1774, when Rodolfo's son succeeded, he was dispossessed of his authority and power. Thereafter the Marquessate was directly administered by Tuscany.
Maria Brignole-Sale, Duchess of Galliera created a charity, Opera Pia Brignole Sale di Voltri, and endowed it with the estate in 1877. However, following her death the charity put the estate up for auction for 201,000 lira in March 1890.
