In 2012, a very bad thing happened in Delhi, which is a big city in India. A group of six men hurt a woman very badly. They did very bad things that nobody should ever do to another person. They hurt her so much that she became very sick and eventually died. This made a lot of people very, very sad.
The woman was just a normal person who was going home from the movies with a friend. The bad men saw her and did bad things to her. They did these bad things because they thought they could get away with it and that nobody would stop them.
But some good people heard about this and decided to do something to help. They wanted to make sure that nobody ever hurt someone else like this again. They wanted to make sure that everyone was safe and that nobody would ever be hurt for being themselves.
This is why a lot of people in India became very angry. They wanted the bad men who hurt the woman to be punished for what they did. They wanted all people, no matter what gender or age or race, to be treated with respect and kindness.
Eventually, the bad men were caught by the police and sent to jail for what they did. But the good people did not stop there. They made changes in India to keep people safer and to make sure that nobody was ever hurt like this again. They spoke up and made their voices heard so that everyone knew that hurting others is never okay.
