Once upon a time in Argentina, there were a group of students and teachers who were protesting because they were not happy with the way things were being run at their schools. They wanted better education, and they were making a lot of noise about it.
One day, the government got really nervous about this. They didn't want people to be unhappy, and they definitely didn't want people to rise up against them. So, they sent a group of policemen who carried long batons, which are called "bastones largos" in Spanish, to the universities where the protesters were.
The idea was to scare them and make them stop protesting. But the police didn't just talk to them or try to calm them down. Instead, they beat the protesters with their batons and arrested many of them. It was a very violent and scary night, and many people were hurt.
This event is known as "La Noche de los Bastones Largos" or "The Night of the Long Batons" in English. It's an important part of history because it shows how governments should not use violence to stop protests, and how it's important to stand up for what you believe in, even if it's hard and scary.
