So, in the year 2004 some people in Leipzig, Germany got really mad about some things the government was doing. They wanted to show their anger and they thought the best way to do it was by going in the streets and protesting peacefully. But they didn't just do it one time, they did it every Monday.
This was called the Monday Demonstration. It was like a big party in the streets, but instead of music and balloons, people carried signs and yelled things they didn't like about the government. They did it every Monday for several months, so that the government knew they were serious and wouldn't just give up.
Lots of people joined the demonstrations, and some even came from other cities to show support. The police were there too, but instead of stopping the protests, they just watched to make sure everything was safe.
In the end, the government listened to what the protesters had to say and changed some of the things they were doing. The Monday Demonstrations showed that when people are upset, they can get together and make their voices heard.
