Maria Theresa of Naples and Sicily

Born 6 June 1772 in Naples, eldest daughter of King Ferdinand I of the Two Sicilies and Queen Maria Carolina, she married Francis II and found herself at the hinge of European history. When Napoleon dissolved the Holy Roman Empire in 1806, the title she held as empress vanished with it. Her husband declared a new Austrian Empire the year before, and she became its first empress under the rebranded throne. She died 13 April 1807, a year into the new order.
