The Sicilian Parliament is a group of people who make important decisions for the area of Sicily, which is a region in Italy. It's like a really big clubhouse where the grown-up leaders get together and talk about how to make things better for the people who live in Sicily.
The Parliament is made up of two parts - the Regional Assembly and the Regional Government. The Regional Assembly is kind of like the big group of people who all come together to talk about the important things that are happening in Sicily. They are elected by the people who live in Sicily to represent them and vote on important decisions.
The Regional Government is made up of a group of people who are chosen by the Regional Assembly to actually make things happen. They are kind of like the helpers who take the ideas and plans from the Assembly and figure out how to make them work. They are led by a President who is chosen by the Regional Assembly.
So, the Sicilian Parliament is made up of two groups of people who work together to make sure the people who live in Sicily have a voice in how things are run and to make sure things are running smoothly.
