Pan-Slavism

Pan-Slavism is an idea that there is a shared culture, language, and history that ties all Slavic people together, regardless of where they live or what language they speak. People who believe in Pan-Slavism think that all Slavic people should support each other, act together, and maybe even create their own country. The idea of Pan-Slavism has been around for many centuries.
