ماريا كريستينا دي بوربون
In 1836 a coup by sergeants of the Spanish Royal Guard at La Granja de San Ildefonso (Province of Segovia) obliged the regent Maria Christina of the Two Sicilies to name a government dominated by the Progressive Party. That government initially superseded the Royal Statute of 1834 by reinstating the Constitution of 1812 (the "Cádiz Constitution"), and called a Constituent Cortes that was also dominated by Progressives, to develop the new Constitution of 1837.
