Answer
Murat's fate was sealed by King Ferdinand IV of Naples, who captured and sentenced him to death. Ferdinand, restored to the Neapolitan throne after Napoleon's downfall, saw Murat as a threat and moved swiftly to eliminate him. Murat's attempt to regain power through an invasion of Calabria ended in disaster, leading to his capture and subsequent execution by firing squad in Pizzo, Calabria, on October 13, 1815.
