Italy in 1848 was a fragmented peninsula with northern states under direct or indirect Austrian imperial rule. Italian nationalists and liberal intellectuals, resentful of reactionary Austrian control and foreign domination, sought to establish independent, liberal governments. King Charles Albert of Piedmont-Sardinia, supported nominally by Pope Pius IX, aspired to unite the peninsula and expel Austrian influence.
Beginning in January 1848, revolts erupted across Italian states and Sicily. Uprisings in Milan and other Lombard cities forced Austrian General Radetzky to retreat to the Quadrilateral fortresses. Charles Albert declared war on Austria in March 1848 and launched a military offensive. Lacking sufficient allies, his forces were defeated by the Austrian army at the Battle of Custoza on 24 July 1848, leading him to sign a truce and withdraw from Lombardy.
Following Charles Albert's defeat and the signed truce, Austria reasserted dominance over a still-divided Italian peninsula. The revolutions ultimately failed to achieve unification or expel Austrian power at this time. Austrian control persisted until it was finally broken during the Second Italian War of Independence, making the 1848 revolts a precursor to eventual Italian unification rather than its achievement.
