Answer:
Supporter of Italian unification.
Step-by-step explanation:
In the years prior the Italian unification, Piedmont-Sardinia was the strongest Italian independent state, not only in military strength, but also in economic strength, since it was the first region of Italy to industrialize.
This is why it was Piedmont-Sardinia the region that led the Italian Unification process. This process advanced from North to South, and many other regions resented Piedmont-Sardinia for it even decades after Italy had become an independent country.
