The Risorgimento (1815–1871) unified the Italian peninsula into the Kingdom of Italy (1861), transforming governance profoundly.
Replaced patchwork of kingdoms, duchies, and Austrian satellites with a centralized national administration—capital first Turin, then Florence, finally Rome (1871).
Adopted the Statuto Albertino (1848 Sardinian constitution) as national charter: bicameral parliament (Senate appointed, Chamber elected), king as executive with ministerial responsibility.
Brigandage in South, Venetian reluctance, papal opposition—central authority contested for decades.
The Risorgimento created the state of Italy; completing the nation took another century—and remains a work in progress.
