Joachim Murat was the first king to rule a kingdom called "
Two Sicilies" by the Edict of
Bayonne, in 1808. Though he controlled the mainland, he never physically controlled the island of
Sicily, where his Bourbon rival had fled from Naples. After the
Congress of Vienna in 1815, the title of king of Two Sicilies was adopted by
Ferdinand IV of Naples in 1816. Under Ferdinand's rule, the
Kingdom of Naples and the
Kingdom of Sicily were unified. He had previously been king separately of both
Naples and
Sicily. ==List of kings==
