King Ferdinand VII abolishes the Spanish Constitution of 1812, returning Spain to absolutism.

The Political Constitution of the Spanish Monarchy, also known as the Constitution of Cádiz and nicknamed La Pepa, was the first Constitution of Spain and one of the earliest codified constitutions in world history. The Constitution was ratified on 19 March 1812 by the Cortes of Cádiz, the first Spanish legislature that included delegates from the entire nation and its possessions, including Spanish America and the Philippines. "It defined Spanish and Spanish American liberalism for the early 19th century."

Absolute monarchy is a form of monarchy in which the sovereign is the sole source of political power, unconstrained by constitutions, legislatures or other checks on their authority.
