Imagine you and your friends have a big field where you all like to play. One day, some people came and took over your field, saying that they own it now and that you can't play there anymore. This is what happened to the Crimean Tatars.
The Crimean Tatars are a group of people who live on the Crimean Peninsula, which is located in Eastern Europe. They have their own culture, language, and traditions. Historically, they were the majority population of Crimea until Soviet leader Joseph Stalin forcibly deported them to Central Asia in 1944. This was done in a very harsh way, with many people being killed, and many others dying on the journey.
After the Soviet Union collapsed in 1991, the Crimean Tatars were allowed to return to their homeland. But then, in 2014, Russia invaded Crimea and annexed it from Ukraine. Many Crimean Tatars have been mistreated and discriminated against by the Russian government since then. They have been arrested, tortured and even killed.
So, in short, the Crimean Tatars are a group of people who were forced out of their homes once and are now facing trouble again. They want to live in peace and safety, but unfortunately, some people are making that very difficult for them.
