Arms of the Two Sicilies Crown
The Royal House of the Two Sicilies is
a branch of the Royal House of Bourbon-Spain. The founder, Felipe V, was a younger grandson of Louis XIV of France. He
became King of Spain on the death of his great-uncle, Carlos II, the last Habsburg King of
Spain, in 1700.
Felipe's eldest surviving son, Fernando VI,
became King of Spain after his father's death. His second son, Carlos, became Duke of
Parma (1731-35), then King of Naples and Sicily (the Two Sicilies), as Carlo VII, in 1734.
His third son, Filippo, evntually became Duke of Parma and Guastalla (1748), founding the
Royal House of Bourbon-Parma.
Fernando VI did not leave surviving issue
when he died in 1759, so the Crown of Spain passed to his brother Carlo VII of the Two
Sicilies. By the terms of the Treaty of Naples of 3 October 1759, Carlo VII became Carlos
III of Spain, and one of its greatest Monarchs.
To prevent the union of the Spanish Crown
with the Italian dominions, Carlos III agreed to abdicate the Two Sicilies throne to his
third, but second surviving son, who became Ferdinando IV of Naples and III of Sicily (and
in 1815 Ferdinando I of the Kingdom of the Two Sicilies). This abdication was enacted in
the Pragmatic Decree of 6 October 1759. The present Royal House of the Two Sicilies
descends in the male line from this King. The present Spanish Royal House descends in the
male line from King Ferdinando's elder brother, Carlos IV.
