The Third Italian War of Independence (Italian: Terza guerra d'indipendenza italiana) was a war between the Kingdom of Italy and the Austrian Empire fought between June and August 1866. The conflict paralleled the Austro-Prussian War and resulted in Austria conceding the region of Venetia (present-day Veneto, Friuli, and the city of Mantua, the last remnant of the Quadrilatero) to France, which was later annexed by Italy after a plebiscite. Italy's acquisition of this wealthy and populous territory represented a major step in the Unification of Italy.
