Macedonia (region)
Greece and North Macedonia have been arguing over the name Macedonia ever since the independence of the country using the name "Republic of Macedonia". North Macedonia had to choose a temporary name in order to be recognized by the United Nations and was known as the Former Yugoslav Republic of Macedonia (FYROM). The two countries have been discussing a solution for a new name that both find acceptable and recently agreed upon the name North Macedonia with the Prespa Agreement between Greece and North Macedonia. Bulgaria has not taken part in the dispute but has some disagreements with North Macedonia. Even though Bulgaria was the first country to recognize Macedonia with its name, it doesn't support the Macedonian ethnicity and language anywhere, but claim it's all Bulgarian.
