Historical Trajectory
Phase I: Rise
Ferdinand VII returned to Spain on March 22, 1814, after Napoleon recognized his kingship through the Treaty of Valençay. Backed by the Manifesto of the Persians signed by 69 Cortes deputies, he executed the Coup of May 1814, declared himself absolute monarch, annulled the liberal Cádiz Constitution and all its decrees, and suppressed the American juntas, consolidating personal autocratic authority over the Spanish monarchy.
Phase II: Zenith
During the Sexenio Absolutista (1814–1820), Ferdinand exercised unchecked royal power, persecuting liberals and attempting to reassert Spanish imperial control over restive American territories. His court became a center of conservative reaction in Europe, aligning with Restoration-era powers. Though colonial revenues were declining, Spain retained nominal authority over a vast overseas empire stretching from the Caribbean to the Pacific coast of South America.
Phase III: Decline
The liberal military revolt of 1820 led by Rafael Riego forced Ferdinand to restore the Cádiz Constitution, inaugurating the Trienio Liberal. A French-led intervention in 1823 crushed constitutional rule and reinstated absolutism during the Década Ominosa. Ferdinand's failure to produce a male heir prompted a succession crisis resolved by restoring female succession, alienating Carlists and sowing the conflict that would erupt into civil war immediately after his death in 1833.
