Charles Albert (Italian: Carlo Alberto I; 2 October 1798 – 28 July 1849) was the King of Sardinia from 27 April 1831 until 23 March 1849. His name is bound up with the first Italian constitution, the Albertine Statute, and with the First Italian War of Independence (1848–1849). The attempt to free northern Italy from Austria represents the first attempt of the House of Savoy to alter the equilibrium established in the Italian peninsula after the Congress of Vienna. These efforts were continued successfully by his son Victor Emmanuel II, who became the first king of a unified Italy in 1861.
