Bulgaria
Overview
Bulgaria is a republic located in the eastern Balkans on the western coast of the Black Sea, with Sofia as its capital. It joined NATO in 2004 and the European Union (EU) in 2007, and with full Schengen accession in 2025 and adoption of the euro on January 1, 2026 confirmed, it has entered the final stage of European integration. It has a population of about 6.4 million, Bulgarian is the official language, and it is known as the birthplace of the Cyrillic script.

Geography and climate
The country has an area of about 111,000 km², half the size of the Korean Peninsula. To the north it borders Romania along the Danube River; to the west, Serbia and North Macedonia; to the south, Greece and Türkiye; and to the east, the Black Sea. The Balkan Mountains (Stara Planina) run east-west through the center of the country, and Musala Peak (2,925 m) in the Rila Mountains in the southwest is the highest point. The climate is continental, with hot, dry summers and cold winters, though the Black Sea coast is relatively mild. The Kazanlak Valley, a rose-growing area, and the Black Sea resort cities of Varna and Burgas are well known.
History
Beginning with the founding of the First Bulgarian Empire in 681, the country has a national history of more than a millennium. After Boris I converted to Christianity in the 9th century, the Cyrillic script was systematized around the Preslav Literary School; the Second Bulgarian Empire revived in 1185 but came under Ottoman rule in 1396 and was governed by the Ottoman Empire for about 500 years. The Treaty of Berlin in 1878 created an autonomous principality, and Bulgaria achieved full independence in 1908; it went through the Balkan Wars and two world wars, losing substantial territory and population. After a communist regime was established in 1946, the socialist system was maintained until 1989; after 1990 the country underwent democratization and transition to a market economy and joined NATO in 2004 and the EU in 2007.
Politics and foreign affairs
It is a republic that combines parliamentary and presidential systems; the president is head of state and has considerable authority in defense and foreign affairs. Political instability has continued since 2021, with seven general elections held in three years; based on the results of the October 2024 snap election, a coalition government led by Prime Minister Rosen Zhelyazkov took office in January 2025. The president is Rumen Radev, and while the country follows a fundamentally pro-European and pro-Atlantic line, reducing dependence on Russian energy and expanding defense spending remain major political issues.
Economy
GDP per capita is about half the EU average, placing it among the lowest-ranking member states, but it has maintained stable growth in recent years. The information technology (IT) outsourcing and software industries have grown rapidly, and Sofia has emerged as a regional IT hub; traditional agricultural products such as rose oil, yogurt, and wine, along with Black Sea tourism, are major exports and sources of foreign currency. The Kozloduy Nuclear Power Plant supplies a significant portion of electricity, and gas supply diversification and renewable energy investment are underway to reduce dependence on Russian energy. The lev is used as the currency until 2026.
Society and culture
About 85% of the population are believers of the Bulgarian Orthodox Church, and Muslims (ethnic Turks and Pomaks) and Roma exist as minorities, making ethnic and religious diversity distinct. Declining fertility and the emigration of young people have reduced the population by more than 20% since the 1990s, and this is cited as a major cause of labor shortages and worsening pension finances. As the birthplace of the 9th-century Cyrillic script, the country observes May 24, the Day of Letters and Culture, as a national holiday; traditional polyphonic singing (Bulgarian women's choirs), the yogurt bacterium Lactobacillus bulgaricus, and rose festivals are cultural symbols. About 10 sites, including Rila Monastery, the ancient city of Nessebar, and the Ivanovo Rock Churches, are listed as UNESCO World Heritage Sites.
Recent developments
In March 2024, following air and sea borders, the Schengen Agreement was fully applied to land borders on January 1, 2025, and border checks with Greece and Romania were abolished. In July 2025, the EU Council gave final approval for euro adoption, confirming that the lev will be replaced on January 1, 2026, and that Bulgaria will become the 21st member of the eurozone. Politically, the lack of policy continuity due to frequent snap elections remains a challenge, and in 2025 citizen protests continued demanding judicial reform and the fight against corruption. In the energy sector, efforts to move away from dependence on Russian gas and discussions on building new nuclear power units are underway, and amid security concerns from the protracted war in Ukraine, plans to increase the defense budget and modernize the military are being pursued. The tourism industry has recovered to pre-pandemic levels, but population decline and a shortage of skilled workers remain constraints on growth.
