Hezbollah is a group of people who live in a place called Lebanon. They call themselves a political party, which means they have ideas about how the country should be run. But some people think they're also a special type of group called a "militia," which means they have weapons and might use them to fight other people.
Hezbollah started a long time ago, in the 1980s, when Lebanon was having a really tough time. A lot of people were fighting each other, and some other countries were involved too. Hezbollah was one of the groups that formed to try to help their community and keep people safe.
Some people like Hezbollah, because they think the group is helping to make Lebanon better. They do things like building hospitals and schools, and helping out after big disasters. But other people don't like Hezbollah, because they think the group is too powerful and might be causing trouble in other parts of the world.
Hezbollah has been in some fights before, and they've been accused of doing some things that other people don't like. But some people still support the group and think they're doing good things for their home country.
