Answer:
Giuseppe Garibaldi - led an army to capture southern Italy
Camillo di Cavour - freed northern Italy from Austrian rule
Giuseppe Mazzini - created a group called Young Italy that promoted Italian independence
King Victor Emmanuel II - served as the first leader of Italy following unification.
Step-by-step explanation:
Piedmont received Lombardy from Austria.
Garibaldi conquered the Kingdom of Two Sicilies (1860) with his "thousand" volunteers.
The states of central Italy were annexed Piedmont, and Victor Emanuel II proclaimed himself King of Italy (1861).
He led the war against Austria, this time in alliance with Prussia (1866), and acquired Venezia.
In 1870, the Pontifical State was also occupied, and Rome became the capital of the Kingdom of Italy, thus realizing the idea of Risorgimento.
