Maria_Christina_of_the_Two_Sicilies

Maria Christina of the Two Sicilies (Italian: Maria Cristina Ferdinanda di Borbone, Principessa delle Due Sicilie, Spanish: María Cristina de Borbón, Princesa de las Dos Sicilias; 27 April 1806 – 22 August 1878) was the queen consort of Spain from 1829 to 1833 and queen regent of the kingdom from 1833, when her daughter became queen at age two, to 1840. By virtue of her short marriage to King Ferdinand VII of Spain, she became a central character in Spanish history for nearly 50 years, thanks to introducing a bicameral model of government based on the Bourbon Restoration in France: the Spanish Royal Statute of 1834.
