Kingdom of Sardinia
On 17 March 1861, law no. 4671 of the Sardinian Parliament proclaimed the Kingdom of Italy, so ratifying the annexations of all other Apennine states, plus Sicily, to the Kingdom of Sardinia. The institutions and laws of the Kingdom were quickly extended to all of Italy, abolishing the administrations of the other regions. Piedmont became the most dominant and wealthiest region in Italy and the capital of Piedmont, Turin, remained the Italian capital until 1865, when the capital was moved to Florence. But many revolts exploded throughout the peninsula, especially in southern Italy, and on the island of Sicily, because of the perceived unfair treatment of the south by the Piedmontese ruling class. The House of Savoy ruled Italy until 1946 when Italy was declared a republic by referendum. In this referendum the southern regions, including Sardinia, voted overwhelmingly in favor of the House of Savoy, with the results being 63.8% in favor of maintaining the monarchy.
Monghidoro
In 1507 Monghidoro was annexed to the Papal States, following the fortunes of Bologna and its territories. 
The Olivetan Order of Benedictin monks (Olivetans) began building a monastery in the village centre in 1528. 
In 1796, with the arrival of Napoleon in Italy, the comune became part of the Cispadane Republic until 1815, when the Congress of Vienna decided to return the territory to Bologna and the Papal States. 
From about 1660 until the advent of large-scale rail transit in the 1840s, Monghidoro was a mandatory stop-over to rest horses and carriage drivers of the aristocratic and fashionably polite society of the European continent on the Grand Tour of Italy on their way to Florence and Rome. 
In 1860 Monghidoro was officially annexed to the Kingdom of Sardinia becoming Kingdom of Italy in 1861.
