Imagine you're playing a game of blocks, and everything is going great! But then, someone comes along and starts knocking over your blocks and making a big mess. That's kind of what's happening in a region in turmoil.
A region is sort of like a big neighborhood, with lots of different lands and people living there. When we say a region is in turmoil, it means that things are really chaotic and everyone is having a hard time. Maybe there's fighting between different groups of people, or a big problem like a natural disaster or a major sickness.
Just like your block game got messed up by someone else's actions, a region in turmoil is caused by things that often aren't in control of the people who live there. But, just like you can work together to clean up the block game and start again, people in a region in turmoil can also work together to solve their problems and make things better.
