FYROM, not only through its name, claims this historical culture and heritage, but also has claimed this history through using Greek symbols on its flag, currency and throughout their nation (such as the “Alexander the Great” airport). The Balkan nations throughout the 20th century have had a history of shifting borders, political instability, and violent ethnic conflict. While perhaps seemingly harmless to one not from the region, FYROM’s actions actually imply irredentism. In fact, many school textbooks and official publications in FYROM contain maps that implicate that there still exist many “unliberated” parts of the “Republic of Macedonia.” As such, FYROM implies similar territorial claims to parts of Greece and of Bulgaria as well. In April 1992, Greece’s major political parties refused to accept any naming of the country which included the word “Macedonia”. In 1992 and 1993, the term FYROM was proposed and adopted by various international organizations (IMF, World Bank, International Conference on the Former Yugoslavia), as well as, various European nations such as France, Spain, and the United Kingdom. Both Greece and FYROM objected to this new appellation. In April 1993, the “Republic of Macedonia” entered the UN, with the compromise that the term FYROM would be acknowledged as a provisional reference term and not a name, a place-keeper until better solutions to the issue could be found. However, tensions continued to escalate, resulting in Greece placing a trade embargo on FYROM from February 1994 to October 1995. In September 1995, the two nations formalized relations in an agreement in which FYROM would remove the Vergina Sun (a Greek symbol) from its flag and remove any irredentist clauses from its constitution. Tensions resulting from this issue have led Greece and FYROM to never establish full diplomatic relations. Greece has also blocked FYROM from joining NATO and the European Union. The issue remained stagnant until June 2018, when Greek Prime Minister Alexis Tsipras and FYROM’s Zaev government signed the Prespa Agreement, which obligates FYROM to change its name to “Republic of North Macedonia” and to renounce any claims on Greek history or culture. The agreement also requires that a Macedonian identity and language of the citizens of Northern Macedonia can exist if made explicitly clear that they have nothing to do with Greek history and the language is clearly declared as Slavic. Other names proposed over the years included New Macedonia, Upper Macedonia, Slavo-Macedonia, Nova Makedonija, Macedonia (Skopje), Vardar Republic, Republic of Skopje, Constitutional Republic of Macedonia, Democratic Republic of Macedonia, Independent Republic of Macedonia, New Republic of Macedonia, and Republic of Upper Macedonia amongst others.
