Isabella II of Spain

Queen of Spain from 1833 to 1868

Isabella II ascended the throne of Spain in 1833 at age two, becoming the only queen regnant in the history of the unified Spanish monarchy. Her three-decade tenure spanned a turbulent transition from absolute rule to a constitutional system, defined by civil conflict, military interference in state affairs, and frequent governmental instability throughout the mid-nineteenth century.

Early Reign and Succession Conflict

Born in Madrid in 1830, Isabella was the daughter of King Ferdinand VII and Maria Christina. To secure her succession, Ferdinand VII abolished the Salic Law. Upon his death in 1833, Isabella was proclaimed sovereign, though her uncle, Infante Carlos, disputed her claim. This challenge triggered the Carlist Wars, a series of conflicts that defined the early years of her minority while her mother served as regent.

Personal Rule and Political Instability

In 1843, the Cortes declared Isabella of age to rule personally. Her reign was characterized by the influence of military generals, such as Baldomero Espartero, and frequent political maneuvering. The Moderate decade, led by Marshal Narváez, saw significant constitutional adjustments that prioritized monarchical authority. Throughout this era, Isabella held the position of Head of State, navigating complex alliances between moderate and progressive political factions.

Marriage and Abdication

Isabella married her cousin, Francisco de Asís, Duke of Cádiz, in 1846. The union was publicly strained, and her personal life frequently drew scrutiny. Following the Glorious Revolution in 1868, Isabella was deposed by a military uprising led by Marshal Francisco Serrano. She went into exile in France and formally abdicated the throne in 1870 in favor of her son, Alfonso XII. She died in Paris in 1904 and was buried at the Royal Crypt of the Royal Monastery of San Lorenzo de El Escorial.
