Okay kiddo, do you know what a "diaspora" means? It's a big word that means people who live outside of their original homeland. So, the "Kashmiri diaspora" refers to Kashmiri people who are now living in different parts of the world, away from their homeland of Kashmir.
Kashmir is a beautiful place that used to be a region in northern India. But now, it's mainly divided between India and Pakistan, and there are some places controlled by China too. Because of conflicts and tensions between these countries, many Kashmiri people have chosen to leave their homes and move to other countries. Some went to nearby places like Pakistan or India, while others went very far away to countries like the United States, Canada, or the United Kingdom.
Even though these Kashmiri people are living in different countries, they still have a special connection to their homeland. They might miss the mountains and scenery, or the food and culture from back home. They might also worry about their families and friends who still live in Kashmir, because there is still conflict and tension there.
Despite being far away, the Kashmiri diaspora often works hard to stay connected with each other and with their culture. They might have community events or celebrations, where they dance, sing, and eat traditional foods. They might also work to spread awareness about what's happening in Kashmir and advocate for peace and justice for their homeland.
