Charles Albert (Italian: Carlo Alberto I; 2 October 1798 – 28 July 1849) was the King of Sardinia and ruler of the Savoyard state from 27 April 1831 until his abdication in 1849. His name is bound up with the first Italian constitution, the Statuto Albertino, and with the First Italian War of Independence (1848–1849).
During the Napoleonic period, Charles Albert resided in France, where he received a liberal education. As Prince of Carignano in 1821, he granted and then withdrew his support for a rebellion which sought to force Victor Emmanuel I to institute a constitutional monarchy. He became a conservative and participated in the legitimist expedition against the Spanish liberals in 1823 known as the "Hundred Thousand Sons of Saint Louis".
