Black Chamber
A black chamber is like a secret room where people can secretly spy on other people's messages. You know how sometimes you write something to someone but you don't want other people to know? Maybe it's a secret message or a love letter. Well, in the past, some countries made secret rooms where they could read other people's secret messages without them knowing.
These secret rooms were called "black chambers". People who worked in black chambers were very good at decoding messages written in secret code. They would read other people's messages and find out what they were saying. This was very helpful for countries who wanted to spy on their enemies or learn secrets from other countries. But it was also a little sneaky and not very nice. Today, black chambers are not used anymore, but people still use secret codes to communicate sometimes.
