Okay kiddo! So a long time ago, there were some countries called "medieval" countries. One of these countries was called Serbia, and they had a really important leader called a "grand župan."
The grand župan was kind of like a king, but not exactly. They were the most important leader in Serbia, and their job was to make sure that everyone in the country was safe and happy. They had a lot of other important jobs too, like making laws and deciding what to do if there was a big problem.
People respected the grand župan a lot, because they were really powerful and had a lot of authority. They were kind of like a superhero, except they didn't have any special powers - they just knew how to run a country really well!
