The state was the center of the struggle for the unification of Italy?

The center was the state of Piedmont in the north-east of modern Italy. Its center was Turin. Piedmont was the most developed state on the territory of modern Italy, where the industrial revolution started earlier than anyone else and the construction of railways began. Piedmont became the Kingdom of Sardinia and the unification of Italy took place around it in 1859-1860. In 1861, an independent Italy appeared with its capital in Turin, in 1870-71 it was moved to Rome, which was previously the center of the Papal States. Only the Vatican remained from her for the Pope. Rome itself could not become the center of the unification of Italy, too conservative.
