The Unification of Italy began in 1815. Following the Congress of Vienna, a movement for Italian unity grew. In 1830, Giuseppe Mazzini founded "Young Italy", a nationalist group. Then, in 1848, like all kings, the King of Sardinia, Victor Emmanuel II, wanted to join additional territories to his Kingdom. The King enlisted Count Camillo Cavour as his Prime Minister to expand his Kingdom. Cavour began to make major changes to Sardinia including improving agriculture and building railroads. Cavour additionally began building up allies. Supported by their new ally France, in 1858, Sardinia gained control of the Austrian's Lombardy territory. The Lombardy victory inspired a wave of Nationalists overthrowing their local leaders. Meanwhile in the Kingdom of Two Sicilies (Naples and Siciliy), Giuseppe Garibaldi also wanted to have a united Italy. Garibaldi recruited 1,000 troops and Cavour supplied Garibaldi with weapons and two ships. With the supplies from Cavour, Garibaldi conquered Naples and Sicily. Garibaldi then did something very interesting. Garibaldi turned over Naples and Sicily to Victor Emmanuel II and Emmanuel was crowned the King of Italy. The only two areas left outside of Italy's control was Rome and Venetia. Venetia was acquired from Germany and in 1861 Italy became a nation. Rome was gained in the Franco-Prussian War in 1870. The Italians shared the common qualities of geography, history, language and culture.
