Ferdinand's absolutist rule rewarded the traditional holders of power—prelates, nobles and those who held office before 1808—but not liberals, who wished to see a constitutional monarchy in Spain, or many who led the war effort against the French but had not been part of the pre-war government. This discontent resulted in several unsuccessful attempts to restore the Constitution in the five years after Ferdinand's restoration. Finally on 1 January 1820 Rafael del Riego, Antonio Quiroga and other officers initiated a mutiny of army officers in Andalusia demanding the implementation of the Constitution. The movement found support among the northern cities and provinces of Spain, and by 7 March the king had restored the Constitution. Over the next two years, the other European monarchies became alarmed at the liberals' success and at the Congress of Verona in 1822 approved the intervention of royalist French forces in Spain to support Ferdinand VII. After the Battle of Trocadero liberated Ferdinand from control by the Cortes in August 1823, he turned on the liberals and constitutionalists with fury. After Ferdinand's death in 1833, the Constitution was in force again briefly in 1836 and 1837, while the Constitution of 1837 was being drafted. Since 1812, Spain has had a total of seven constitutions; the current one has been in force since 1978.
