The remnants of the Bourbon armies finally surrendered in February 1861 and Piedmont's king, Victor Emmanuel, was crowned king of Italy a month later. The rapid collapse of the Kingdom of the Two Sicilies took everyone by surprise Cavour feared Garibaldi would capitalize on this victory and march on Rome, but Cavour and Garibaldi agreed to unify their halves of Italy and their respective armies. After ejecting the Bourbon forces from Sicily Garibaldi crossed to the mainland and marched on Naples, the capital. Ten months later the second stage of the war began as the legendary Italian nationalist Giuseppe Garibaldi landed in Sicily with 1,000 volunteers, intent on overthrowing the Bourbon Kingdom of the Two Sicilies. A series of bloody clashes culminating in Solferino-San Martino, the largest battle on European soil since Leipzig in 1813, resulted in decisive defeat for the Austrians and the end of the war in the north. Beyond the battlefields, the outcome of the war represented a culminating triumph for the Piedmontese prime minister, Camillo di Cavour, whose success in winning and retaining French and British support for his plans for Italian unification has provided a model for the leaders of junior partners allied to world powers ever since.īetween April and July 1859 the first stage of the war pitted Napoleon III's French armies and their Piedmontese allies against the Habsburg Austrian forces that had invaded Piedmont. The savage nature of the fighting led to the foundation of the Red Cross and the establishment of the Geneva Conventions, while the colorful uniforms and aggressive doctrine espoused by the French Army in particular were to influence those on both sides of the American Civil War. Overshadowed by subsequent conflicts, the war saw the first widespread use of railroads in war and the first battlefield deployment of rifled field artillery, as well as the last major battle in world history where all the forces involved were under the personal command of their monarchs.

The culmination of decades of nationalist aspiration and cynical Realpolitik, the Second War of Italian Unification saw Italy transformed from a patchwork of minor states dominated by the Habsburg Austrians into a unified kingdom under the Piedmontese House of Savoy.
