Although in the interests of stability Ferdinand issued a general amnesty to all those involved in the 1820 coup and the liberal government that followed it, the original architect of the coup, Rafael del Riego, was executed. The liberal "Partido Progresista", however, continued to exist as a political force, even if it was excluded from actual policy-making by Ferdinand's restored government. Riego himself was hanged, and he would become a martyr for the liberal cause in Spain and would be memorialized in the anthem of the Second Spanish Republic, "El Himno de Riego", more than a century later.
