Austro-French Piedmontese War

1859
Also known as: war of Italian unification

Quick Summary

The Austro-French Piedmontese War, also known as the Second War of Italian Independence, occurred in 1859. This conflict was a pivotal event in the unification of Italy.1

The war began when Austria declared war on Piedmont in April 1859, following secret talks between Piedmont's Prime Minister Cavour and Napoleon III of France, who had formed an alliance. The French and Piedmontese forces achieved a victory at the Battle of Magenta on June 4, leading to their triumphant entry into Milan.23

The final major engagement was the bloody Battle of Solferino on June 24, 1859. Despite heavy casualties on both sides, the Franco-Piedmontese army ultimately prevailed, resulting in the annexation of most of Lombardy by Sardinia-Piedmont. However, Napoleon III, disillusioned with the war's progress and fearing Prussian intervention, arranged an armistice at the Conference of Villafranca in July 1859. This preliminary peace treaty ceded Lombardy to Piedmont but left Venetia under Austrian control, a compromise that Cavour found unacceptable.14
