Which 1820 uprising forced Ferdinand VII to abolish the Inquisition again?

The 1820 uprising that forced Ferdinand VII to abolish the Inquisition again was the Riego uprising.

Led by Lieutenant Colonel Rafael del Riego, the military revolt began on 1 January 1820 at Las Cabezas de San Juan in Andalusia. The troops had been assembled for an expedition against Spanish-American independence movements, but Riego and his supporters instead demanded the restoration of the liberal Constitution of 1812.

Although the uprising initially struggled and Riego’s column dwindled, other garrisons joined the revolt. Ferdinand VII was compelled to restore the constitution and, on 9 March 1820, abolish the Inquisition for a second time. This inaugurated the Trienio Liberal, the constitutional period of 1820–1823.

The event is sometimes called the Riego pronunciamiento or the Revolution of Cabezas de San Juan. It is not the Glorious Revolution, the 1808 Dos de Mayo uprising, or the Comuneros revolt: those refer to different episodes in Spanish or European history.
