KGB

The KGB was like a group of spies who worked for the government in Russia a long time ago. Their job was to gather information about people who might be doing bad things or working against the government, and to make sure that everyone was behaving the way they were supposed to. They would use all sorts of sneaky tactics to get information, like listening in on people's phone calls or hiding cameras in their offices. They were very good at what they did, and they were feared by many people because they had a lot of power. However, the KGB doesn't exist anymore because the government in Russia realized that having a group like the KGB was not a good thing for the country.
