Final answer:
Before Italian nationalism, Italy was separated into city-states and kingdoms. Napoleon Bonaparte's campaigns in Italy led to political changes. The correct option is A.
Step-by-step explanation:
Before the start of Italian nationalism, Italy was separated into city-states and kingdoms. Foreign powers such as Spain and France had dominated Italy since the 1500s, extinguishing the independence of most of the Italian city-states during the Italian Wars.
Austria came to dominate the north, while the south was ruled by the Kingdom of the Two Sicilies. In the middle was the Papal States, ruled directly by the pope. Napoleon Bonaparte played a significant role in the political changes in Italy.
His campaigns in Italy led to political changes and the unification of certain regions. He supported the idea of Italian unity and his invasion of Italy caused further fragmentation of the Italian states. The correct option is A.
