Okay kiddo, let me explain what happened when the Jews were expelled from Sicily.
A long time ago, like a really long time ago, there were people who believed in different gods and had different ways of living. They had different cultures and languages too.
In Sicily, there were people who followed a religion called Christianity. They believed in Jesus Christ and had their own churches to worship in. But there were also people who followed a religion called Judaism. They believed in God but didn't believe in Jesus Christ.
These two groups of people lived together in Sicily for some time, but eventually, the Christian leaders thought that the Jews were causing problems. They didn't want them to practice their religion anymore and even accused them of bad things they didn't do.
So, the Christian leaders kicked the Jews out of Sicily. They had to leave their homes and belongings behind and find a new place to live. It was really hard for them to start over and they faced a lot of challenges along the way.
This wasn't fair, and it's important to remember that everyone deserves to be treated equally no matter what their beliefs are. We should always respect and appreciate people for who they are, and never judge or discriminate against them because of their beliefs or backgrounds.
