Parliament evolved from the curiae generales of bishops, lords and cities representatives that advised the Sicilian monarch.

[citation needed] After a period in the background during the reign of Charles I of Anjou, the Parliament became the central focus of the organization of the Sicilian Vespers.

At this time, the Sicilian Parliament consisted primarily of landowners, mayors of cities, counts and barons, and was chaired and convened by the king.

Parliament had the constitutional responsibility to elect the king and to guarantee the proper conduct of ordinary justice exercised by executioners, judges, notaries and other officials of the kingdom.

In 1410 the Sicilian Parliament was held at Palazzo Corvaja in Taormina, in the presence of Queen Blanche I of Navarre - a historic meeting for the election of the King of Sicily after the death of Martin II.

After sixteen months of de facto autonomous rule, the Parliament was declared void by the Bourbon dynasty, who offered the vacant throne of Sicily to the Prince Ferdinando, Duke of Genoa, the second son of Carlo Alberto of Savoy.
