The Sicilian Regional Assembly is the legislative body of Sicily. While it has a long history as an autonomous region, the modern Region of Sicily was established by Royal Decree on May 15, 1946, before the Italian Republic. The Regional Assembly has the widest legislative power in Italy and is the only regional assembly to have the title of "parliament" whose members are called "deputies" like those in Rome. Ninety deputies are elected every five years in the nine provinces.
