Liberum veto

Liberum veto is a fancy Latin phrase that means "I say no" or "I veto". It was a rule that was used in the olden times in a country called Poland, which is now in Europe.

So, long ago in Poland, whenever a group of people called the lawmakers wanted to make a new law, each person had the power to say "no" and the whole thing would be stopped. This was called the liberum veto.

Imagine if you were playing a game with your friends, and one person had the power to say "I don't want to play this game anymore" and everyone would have to stop playing. That's kind of like how liberum veto worked in Poland.

This rule sometimes caused problems because one person or a small group could stop the whole country from making new laws or doing things that were important. It wasn't always fair and sometimes things didn't work out so well. Eventually, Poland got rid of the liberum veto rule and they have a different way of making decisions now.
