A royal house divided: why two branches claim the throne of the Two Sicilies
In short: The House of Bourbon-Two Sicilies ruled Southern Italy for over a century, but its modern legacy is defined by a bitter, decades-long succession dispute. Since 1960, two rival lines have clashed over the rightful headship, a conflict recently reignited by a controversial shift in traditional inheritance laws.
The Bourbon-Two Sicilies family descends from the Capetian dynasty via Philip, Duke of Anjou, a grandson of Louis XIV of France. In 1759, the family was established in Italy when Ferdinand IV and III became the monarch of Naples and Sicily. These realms were formally merged into the Kingdom of the Two Sicilies in 1816. The dynasty’s reign ended in 1861, when the kingdom was annexed by the newly founded Kingdom of Italy following the overthrow of King Francis II by Giuseppe Garibaldi.
The current schism began in 1960 upon the death of Prince Ferdinand Pius, who left no male heir. The succession became a battle between the senior Calabrian line, currently led by Prince Pedro, and the junior Castro line, led by Prince Carlo. The dispute centers on the 1900 Act of Cannes, in which Carlos, the elder brother of the late Prince Ranieri, allegedly renounced his claims to the Two Sicilies throne before marrying the heiress to the Spanish crown. While the senior line argues the renunciation was conditional or invalid under house laws, the junior line has maintained its claim for decades.
Tensions escalated in 2016 when Prince Carlo unilaterally abolished the traditional male-line primogeniture in favor of absolute primogeniture, naming his eldest daughter as his heir. This move directly contradicted a 2014 reconciliation pact, which had recognized both branches as members of the same house. Prince Pedro publicly objected, arguing the change violated their agreement, while Prince Carlo defended the shift as a necessary alignment with modern international and European standards against gender discrimination. Today, the two branches remain deadlocked, with the senior line backed by an investigation from five Spanish state institutions, while the junior line continues to assert its own path.
