Italy’s Borders Explained: Unification, WWI Gains, and WWII Losses

Italy’s borders were once a patchwork of separate states, and this concise history video traces how that changed over time. From the Kingdom of the Two Sicilies, the Papal States, Lombardy-Venetia, and the Kingdom of Sardinia to the rise of a unified Kingdom of Italy, it follows the Risorgimento and the capture of Rome in 1870.

The story then moves into Italy’s colonial ambitions, World War I territorial gains like South Tyrol and Istria, and the frustration that followed when most of Dalmatia was not obtained. That resentment helped fuel Mussolini’s expansionist agenda in World War II, when Italy temporarily expanded before losing its African colonies, Dalmatian lands, and Istria. Trieste’s postwar division and the final settlement of Italy’s borders bring the timeline to the present.

Ideal for viewers interested in Italian history, European borders, unification of Italy, World War I and World War II history, and short educational history narration.
