The flag of the Constitutional Kingdom of the Two Sicilies, a white field charged with the coats of arms of Castile, Leon, Aragon, Two Sicilies, and Granada, was modified by Ferdinand II through the addition of a red and green border. This flag lasted from 3 April 1848 until 19 May 1849. The Provisional Government of Sicily, which lasted from 12 January 1848 to 15 May 1849 during the Sicilian Revolution, adopted the Italian tricolour, defaced with the trinacria, or triskelion.
