 In 1848, Charles Albert conceded a constitution known as the "Statuto Albertino" to Piedmont-Sardinia, which remained the basis of the Kingdom's legal system even after Italian unification was achieved and the Kingdom of Sardinia became the Kingdom of Italy in 1861.The Kingdom of Italy was the first Italian state to include the Italian Peninsula since the fall of the Roman Empire.But when Victor Emmanuel was crowned King of Italy in 1861, his realm did not include the Venetia region (subject to Habsburg governance), Lazio (with Rome), Umbria, Marche and Romagna (with the Papal town of Bologna).
