Pan-Slavism is a political and cultural movement that emerged in the 19th century, advocating for the unity of Slavic peoples across Europe, particularly in response to the influence of Austro-Hungarian and Ottoman empires. This movement sought to promote Slavic identity, language, and culture while emphasizing solidarity among Slavic nations, which played a significant role in the nationalistic sentiments leading up to the disintegration of Yugoslavia in the 1990s.
