Imagine there is a group of people who have different beliefs than others. These people believe in something called Jehovah, which is a name for God. They call themselves Jehovah's Witnesses.
Now, some people don't like that these Jehovah's Witnesses are different and they don't believe in the same things that they do. They might be mean to them or try to hurt them. That's called persecution.
The persecution of Jehovah's Witnesses is when they are treated badly, not allowed to practice their religion, or punished just because they believe in something different than other people. This has happened in many different parts of the world, and it's not a nice thing to do.
Sometimes, governments have tried to stop Jehovah's Witnesses from practicing their religion or put them in jail just because of their beliefs. This is not fair, because people should be allowed to believe what they want and practice their religion without being afraid.
Overall, the persecution of Jehovah's Witnesses is when they are treated badly just because they believe in something different from other people. It's not okay to treat people like this, and everyone should be allowed to believe what they want and practice their religion without being persecuted.
