The Kingdom of Sardinia was a state in Southern Europe that existed from 1720 to 1861. It included the island of Sardinia and parts of the Italian mainland, such as Piedmont and Savoy. The kingdom played a significant role in the unification of Italy, serving as a base for the movement led by figures like Giuseppe Garibaldi and Count Camillo di Cavour. In 1861, the Kingdom of Sardinia became the foundation for the newly unified Kingdom of Italy. Its capital was Turin, which was an important cultural and political center during this period. The kingdom's legacy continues to influence Italian history and identity.
