The monarchial authority of Charles IV spanned two turbulent decades from 1788 to 1808, marking a period of profound instability within the Spanish Empire. Born in Portici in 1748, he transitioned from his role as Prince of Asturias to sovereign, ultimately presiding over a reign characterized by shifting alliances and the eventual collapse of his direct rule.
Ascension and Administrative Style
Succeeding his father, Charles III, in 1788, Charles IV inherited a stable kingdom that soon faced internal and external pressures. While he maintained the external appearances of an absolute monarch, his actual involvement in governance remained passive. Administration was largely delegated to his wife, Maria Luisa, and his first minister, Manuel de Godoy. This detachment from active policy-making during the rise of Napoleon Bonaparte and the French Revolution alienated key segments of his subjects.

Despite the political challenges of the era, the crown continued to fund significant scientific and exploratory missions. Notable endeavors included the Malaspina Expedition, which gathered extensive geographical and botanical data, and the Royal Botanical Expeditions to New Spain and New Granada. In 1803, Charles IV authorized the Balmis Expedition to implement smallpox vaccinations across overseas territories, and he permitted the Prussian scientist Alexander von Humboldt to conduct research throughout Spanish America.
Economic Strain and Political Collapse
Financial exigencies dominated the later years of his reign, as involvement in French-led wars exhausted the treasury. Attempted structural reforms, including those proposed by Gaspar Melchor de Jovellanos, aimed to modernize agriculture by addressing land ownership and the influence of the Church. A 1804 decree forcing the Catholic Church to collect long-term mortgages placed elite landowners under severe financial stress. These tensions culminated in the Tumult of Aranjuez in March 1808 and the El Escorial Conspiracy, leading to his forced abdication and the subsequent rise of Joseph Bonaparte.
