Italian unification (), also known as the Risorgimento (meaning "the Resurgence"), refers to the Italian movement that united the Italian states in the 19th century. The movement began in 1815 with the Congress of Vienna. It ended in 1871, when Rome became the capital of the Kingdom of Italy by the efforts of Count of Cavour, the prime minister of Piedmont, and Giuseppe Garibaldi, an Italian national hero who united southern Italy. That allowed King Victor Emmanuel II to become the first king of Italy.
