A Corsican guard is like having a special group of people who protect you. It's kind of like having your own personal superhero team to keep you safe. The Corsican guard was a group of soldiers from the island of Corsica, who were really good at defending and protecting people. They were called the Corsican guard because they all came from the same place and worked together to protect important people, like kings or queens. The Corsican guard was really important because they were always on the lookout for danger and would do everything they could to keep their king or queen safe. Think of them like the ultimate bodyguards.
