Final answer:
Three key figures in the Unification of Italy were King Victor Emmanuel II, who offered leadership; Giuseppe Garibaldi, who led key military campaigns; and Count Camillo di Cavour, the political strategist behind the unification.
Step-by-step explanation:
The Unification of Italy was a complex process that began in the 19th century and was led by three key figures: Victor Emmanuel II, Giuseppe Garibaldi, and Count Camillo di Cavour. Victor Emmanuel II was the King of Piedmont-Sardinia, which became the core of the future Italian state. His contributions to the unification included providing the political and diplomatic ties necessary for unification as well as offering a royal figure as the head of a united Italy. Giuseppe Garibaldi was a renowned patriot and soldier whose military campaigns successfully incorporated the southern part of Italy, thus playing a crucial role in the physical unification of the country. The most significant political figure was Count Camillo di Cavour, Prime Minister of Piedmont-Sardinia and the architect of the unification. He used diplomacy, strategic alliances, and war to expand Piedmont-Sardinia's territory and to bring about a unified Italy. Cavour’s political skills, in conjunction with Garibaldi’s military successes and Victor Emmanuel’s leadership, shaped the path to a unified Italian state.
