7 Countries of the Former Yugoslavia: From Yugoslavia to Today’s Balkan States
The former Yugoslavia was a multi-ethnic, multi-religious country in Southeast Europe that existed through much of the 20th century. Its complex history, rich culture, and turbulent political shifts shaped the modern states that emerged after its dissolution. Today, the combined population of all the countries that once formed Yugoslavia is around 20 million people.
The Birth and Breakup of Yugoslavia
Yugoslavia was officially formed in 1918 as the Kingdom of Serbs, Croats, and Slovenes, uniting various South Slavic peoples after the collapse of the Austro-Hungarian and Ottoman Empires. It became the Kingdom of Yugoslavia in 1929 and later, after World War II, transformed into the Socialist Federal Republic of Yugoslavia under Josip Broz Tito. Tito’s leadership kept the country united through a balance of ethnic representation and a non-aligned foreign policy during the Cold War. However, after his death in 1980, rising nationalism, economic decline, and political instability began to strain the federation.
Growing ethnic tensions, disputes over autonomy, and the weakening of federal authority led to violent conflicts, including the Croatian War of Independence, the Bosnian War, and later the Kosovo War. International interventions, economic sanctions, and shifting political alliances further accelerated the breakup, leaving a legacy of both reconciliation efforts and unresolved disputes.
Present-Day Countries That Were Part of Yugoslavia
🇷🇸 Serbia
Serbia is the largest successor state of the former Yugoslavia, located in the central and southern Balkans. Its capital, Belgrade, is one of Europe’s oldest cities, with other important cities including Novi Sad and Niš. The official language is Serbian, which uses both Cyrillic and Latin scripts. Serbia has a population of around 6.6 million and a GDP of roughly $80 billion, with its economy based on agriculture, manufacturing, IT services, and energy production.
The majority religion is Serbian Orthodox Christianity, deeply influencing the country’s traditions and festivals. Serbia is known for its vibrant music scene, medieval monasteries, and the EXIT music festival. A notable fact is that it is home to parts of the Danube River and the Đerdap National Park, which contains the largest gorge in Europe. Serbia aspires to join the European Union and is already a member of the United Nations, the OSCE, and other regional organizations. However, its relations with Kosovo remain a central issue in its foreign policy and integration prospects. The currency of Serbia is the Serbian dinar (RSD).
🇭🇷 Croatia
Croatia lies along the Adriatic Sea and is famous for its stunning coastline and historic cities. The capital is Zagreb, with major cities such as Split, Rijeka, and Dubrovnik, the last being a UNESCO World Heritage Site. The official language is Croatian, written in the Latin alphabet. Croatia’s population is about 3.8 million, with a GDP of approximately $79 billion, driven by tourism, shipbuilding, agriculture, and technology services.

A unique fact is that Sarajevo hosted the 1984 Winter Olympics, making it the only Balkan city to have done so. Bosnia and Herzegovina is a potential candidate for EU membership and is part of the Central European Free Trade Agreement (CEFTA). The Dayton Agreement, which ended the Bosnian War in 1995, still shapes its complex political structure today. The currency of Bosnia and Herzegovina is the convertible mark (BAM).

A remarkable fact is that Lake Ohrid is one of Europe’s oldest and deepest lakes, a UNESCO World Heritage Site. The country joined NATO in 2020 and is a candidate for EU membership, with accession talks ongoing. Its recent name change from Macedonia to North Macedonia resolved a long-standing dispute with Greece, unlocking its Euro-Atlantic integration path. The currency of North Macedonia is the Macedonian denar (MKD).
