Maria Amalia of Bourbon-Two Sicilies—whose full name was Maria Amalia Ferdinanda of Bourbon—was a Princess of the Two Sicilies by birth and became an Infanta of Portugal and Spain following her marriage to Infante Sebastian of Bourbon-Spain. She was born in Pozzuoli on February 25, 1818, and died in Madrid on November 6, 1857.
The tenth child of Francis I of the Two Sicilies and Maria Isabella of Spain, Maria Amalia played no significant political role, though a strategic marriage had been hoped for. She met Sebastian of Bourbon-Spain during the wedding of her sister, Maria Cristina, and married him in Madrid on May 25, 1832. However, the marriage produced no children and took place amidst political tension between the supporters of Isabella II and those of Carlos María Isidro of Bourbon-Spain.
Following the death of Ferdinand VII in 1833, dynastic conflicts arose that led to the regency of Maria Cristina. Sebastian Gabriel, initially loyal to the late king, became a prominent Carlist leader. In 1838, his mother married Carlos, becoming Queen of the Carlists, and the First Carlist War ended in 1839.
Maria Amalia died on November 6, 1857, during a period of instability between Carlists and Isabellines; her passing went largely unnoticed at the Madrid court. After her death, Sebastian Gabriel remarried, wedding Infanta Maria Cristina of Spain, a cousin of Isabella II.
