Croatia is a country located in Southeast Europe, on the Adriatic Sea, known for its rich history and diverse culture. It emerged as a significant national entity during the 20th century, particularly during the decline of communism in Eastern Europe, which led to the rise of nationalism and the eventual declaration of independence from Yugoslavia in 1991. The political turmoil and ethnic conflicts in the region during this period highlight the impacts of totalitarian regimes and the struggle for national identity.
