Elias, Duke of Parma and Piacenza was the head of the House of Bourbon-Parma and pretender to the defunct throne of Parma between 1950 and 1959. From 1907 to 1950 he served as regent for the claims of his two older disabled brothers.
Princess Maria Christina of Bourbon-Parma ; she died unmarried.
Through his fourth daughter, Princess Alicia, he is great-grandfather of Prince Pedro, Duke of Calabria, one of two claimants to the thone of the Two Sicilies.
Regent for his brothers
In 1907 Elias' father Robert died and was succeeded in his ducal claims of Parma by his son Enrico who was mentally disabled. Less than four months later the Grand Marshal of the Austrian court declared Enrico and five of his siblings legally incompetent. Elias became regent for Enrico's claims and guardian for his disabled siblings. In 1907 Elias was made a knight of the Order of the Golden Fleece by the Emperor Franz Joseph of Austria. In 1910 Elias came to an agreement with his half-siblings, his father's children by his second wife, about the division of their father's estate. Elias was to have half of the estate in order to support his rank as head of the family; this half included the château de Chambord. In 1915 Chambord was sequestered by the French government as alien property, since Elias held a commission in the Austro-Hungarian Army. Liquidation proceedings were started in 1919 in application of the Treaty of Saint-Germain-en-Laye, which gave the Allies the right to keep such property. Elias' half-brothers, Sixtus and Xavier took Elias to court to obtain a greater share of their father's estate. They claimed that the 1910 family agreement violated the French law which mandated equal division between siblings. In 1925 the French courts determined that Sixtus and Xavier should have a larger share, but in 1928 this judgement was overturned on appeal. In 1932 the court of cassation upheld the appeal on the grounds that there was a valid agreement between the siblings to an unequal division. Elias' rights to the château de Chambord were thereby recognised - but the wartime confiscation was upheld and Elias was financially compensated with 11 million francs. In 1939 Enrico died and was succeeded in his ducal claims of Parma by his brother Giuseppe who also was mentally disabled. Elias continued to act as regent. In 1950 Giuseppe died and Elias succeeded as pretender of Parma. Elias died at Friedberg, Styria in 1959. He and his wife are buried in the nearby village of Mönichkirchen.
