The significant event that tried to unify Italy under a shared national identity in the 19th century is known as the Italian Unification or Risorgimento. This movement, which spanned from the early to the late 19th century, involved various leaders, including Giuseppe Garibaldi and Count Camillo di Cavour. The culmination of this unification was the proclamation of the Kingdom of Italy in 1861, when Victor Emmanuel II became its first king. The Risorgimento not only fostered a sense of Italian nationalism but also had profound impacts on the political landscape of Europe, challenging existing empires and reconfiguring power dynamics.
