Princess Maria Carolina of Bourbon Two Sicilies celebrated her extravagant 21st birthday in Sardinia with opulent gifts from luxury brands like Hermes, a lavish party at the Cervo Hotel, and a four-tiered cake. Despite her royal titles, she is not in line to inherit any thrones, as her family's lineage traces back to the House of Bourbon-Two Sicilies. The event, likened to a wedding spectacle, showcased the family's ties to European royalty and their opulent lifestyle. Carolina and her sister, Princess Maria Chiara, engage in charitable work and social activities, promoting Southern Italy's heritage and participating in cultural events. The Bourbon-Two Sicilies family, rooted in European aristocracy, continues to maintain traditions and cultural contributions despite no longer holding ruling power.
