Austria threatened war on Piedmont in 1858 primarily due to rising nationalist sentiments in Italy and the desire for unification, which were viewed as threats to Austrian influence in the region. The Piedmontese government, led by Count Camillo di Cavour, sought to expand its power and ally with France to challenge Austrian dominance. The secret negotiations between Cavour and Napoleon III for military support against Austria heightened tensions, prompting the Austrians to issue the threat. This conflict ultimately contributed to the wider Italian unification movement.
King Charles Albert (1798-1849) was King of Sardinia when Sardinia (which held lands south of Switzerland in mainland Europe) attacked Austria in the First War of Italian Independence (1848).
