, and leaving large populations of ethnic Bulgarians outside the new country.
This significantly contributed to Bulgaria's militaristic foreign affairs approach during the first half of the 20th century.
The Bulgarian principality won Serbo-Bulgarian War, a war against Serbia and incorporated the semi-autonomous Ottoman territory of Eastern Rumelia in 1885, proclaiming itself an independent state on 5 October 1908. In the years following independence, Bulgaria increasingly militarised and was often referred to as "the Balkan Prussia". It became involved in three consecutive conflicts between 1912 and 1918—two Balkan Wars and World War I. After a disastrous defeat in the Second Balkan War, Bulgaria again found itself fighting on the losing side as a result of its alliance with the Central Powers in World War I. Despite fielding more than a quarter of its population in a 1,200,000-strong army and achieving several decisive victories at Battle of Doiran (1917), Doiran and Battle of Monastir (1917), Monastir, the country capitulated in 1918. The war resulted in significant territorial losses and a total of 87,500 soldiers killed. More than 253,000 refugees from the lost territories Immigration, immigrated to Bulgaria from 1912 to 1929, placing additional strain on the already ruined national economy.
Between 19 October 1925 and 29 October 1925, the Incident at Petrich, nicknamed "the War of the Stray Dog" occurred, which was a minor armed conflict. Greece invaded Bulgaria, after the killing of a Greek captain and sentry by Bulgarian soldiers. The conflict was settled by the League of Nations, and resulted in a Bulgarian diplomatic victory. The League ordered a ceasefire, Greek troops to withdraw from Bulgaria and Greece to pay £45,000 to Bulgaria.

The resulting political unrest led to the establishment of a royal authoritarianism, authoritarian dictatorship by Tsar Boris III of Bulgaria, Boris III (1918–1943). Bulgaria entered World War II in 1941 as a member of Axis powers, the Axis but declined to participate in Operation Barbarossa and Rescue of the Bulgarian Jews, saved its Jewish population from deportation to Nazi concentration camps, concentration camps. The sudden death of Boris III in mid-1943 pushed the country into political turmoil as the war turned against Germany, and the communist guerrilla movement gained momentum. The government of Bogdan Filov subsequently failed to achieve peace with the Allies. Bulgaria did not comply with Soviet demands to expel German forces from its territory, resulting in a declaration of war and an invasion by the USSR in September 1944. The communist-dominated Fatherland Front (Bulgaria), Fatherland Front took power, ended participation in the Axis and joined the Allied side until the war ended. Bulgaria suffered little war damage and the Soviet Union demanded no reparations. But all wartime territorial gains, with the notable exception of Treaty of Craiova, Southern Dobrudzha, were lost.

The 1944 Bulgarian coup d'état, left-wing coup d'état of 9 September 1944 led to the abolition of the monarchy and People's Court (Bulgaria), the executions of some 1,000–3,000 dissidents, war criminals, and members of the former royal elite. But it was not until 1946 that a One-party state, one-party people's republic was instituted following a referendum. It fell into the Soviet sphere of influence under the leadership of Georgi Dimitrov (1946–1949), who established a repressive, rapidly industrialising Stalinist state. By the mid-1950s, standards of living rose significantly and political repression eased. The Soviet-style planned economy saw some experimental market-oriented policies emerging under Todor Zhivkov (1954–1989). Compared to wartime levels, national Gross domestic product, GDP increased five-fold and per capita GDP quadrupled by the 1980s, although severe debt spikes took place in 1960, 1977 and 1980. Zhivkov's daughter Lyudmila Zhivkova, Lyudmila bolstered national pride by promoting Bulgarian heritage, culture and arts worldwide. Facing declining birth rates among the ethnic Bulgarian majority, Zhivkov's government in 1984 forced the minority ethnic Bulgarian Turks, Turks to adopt Slavic names in an attempt to erase their identity and assimilate them. These policies resulted in the emigration of some 300,000 ethnic Turks to Turkey.
The Communist Party was forced to give up its political monopoly on 10 November 1989 under the influence of the Revolutions of 1989. Zhivkov resigned and Bulgaria embarked on a transition to a parliamentary system, parliamentary democracy. The first free elections in June 1990 were won by the Communist Party, now rebranded as the Bulgarian Socialist Party. A Constitution of Bulgaria, new constitution that provided for a relatively weak elected president and for a prime minister accountable to the legislature was adopted in July 1991. The new system initially failed to improve living standards or create economic growth—the average quality of life and economic performance remained lower than under communism well into the early 2000s. After 2001, economic, political and geopolitical conditions improved greatly, and Bulgaria achieved high Human Development status in 2003. It became a member of NATO in 2004
and participated in the War in Afghanistan (2001–2021), War in Afghanistan. After several years of reforms, it joined the

Geography

Bulgaria is a middle-sized country situated in Southeast Europe, in the east of the Balkans. Its territory covers an area of , while land borders with its five neighbouring countries run a total length of , and its coastline is long. Bulgaria's geographic coordinates are 43rd parallel north, 43° N 25th meridian east, 25° E.
The most notable topographical features of the country are the Danubian Plain (Bulgaria), Danubian Plain, the Balkan Mountains, the Upper Thracian Plain, and the Rila-Rhodope Mountains, Rhodope massif. The southern edge of the Danubian Plain slopes upward into the foothills of the Balkans, while the

and broadening as it reaches the Bulgarian Black Sea Coast, Black Sea coast.
The Balkan mountains run laterally through the middle of the country from west to east. The mountainous southwest has two distinct Glacial landform, alpine type ranges—Rila and Pirin, which border the lower but more extensive Rhodope Mountains to the east, and various medium altitude mountains to west, northwest and south, like Vitosha, Osogovo and Belasitsa. Musala, at , is the highest point in both Bulgaria and the Balkans. The Black Sea coast is the country's lowest point.
Plains occupy about one third of the territory, while plateaux and hills occupy 41%. Most rivers are short and with low water levels. The longest river located solely in Bulgarian territory, the Iskar (river), Iskar, has a length of . The Struma River, Struma and the Maritsa are two major rivers in the south.
Climate
Bulgaria has a varied and changeable climate, which results from being positioned at the meeting point of the Mediterranean climate, Mediterranean, Oceanic climate, Oceanic and Continental climate, Continental air masses combined with the barrier effect of its mountains. Northern Bulgaria averages cooler, and registers more precipitation, than the regions south of the Balkan mountains. Temperature amplitudes vary significantly in different areas. The lowest recorded temperature is , while the highest is . Precipitation (meteorology), Precipitation averages about per year, and varies from in Dobrudja to more than in the mountains. Continental air masses bring significant amounts of snowfall during winter.
Considering its relatively small area, Bulgaria has variable and complex climate. The country occupies the southernmost part of the continental climate, continental climatic zone, with small areas in the south falling within the Mediterranean climate, Mediterranean climatic zone. The continental zone is predominant, because continental air masses flow easily into the unobstructed Danubian Plain (Bulgaria), Danubian Plain. The continental influence, stronger during the winter, produces abundant snowfall; the Mediterranean influence increases during the second half of summer and produces hot and dry weather. Bulgaria is subdivided into five climatic zones: continental zone (Danubian Plain, Pre-Balkan and the higher valleys of the Transitional geomorphological region); transitional zone (Upper Thracian Plain, most of the Struma and Mesta valleys, the lower Sub-Balkan valleys); continental-Mediterranean zone (the southernmost areas of the Struma and Mesta valleys, the eastern Rhodope Mountains, Sakar and Strandzha); Black Sea zone along the coastline with an average length of 30–40 km inland; and alpine zone in the mountains above 1000 m altitude (central Balkan Mountains, Rila, Pirin, Vitosha, western Rhodope Mountains, etc.).
Biodiversity and conservation

The interaction of climatic, hydrological, geological and topographical conditions has produced a relatively wide variety of plant and animal species.
Bulgaria's biodiversity, one of the richest in Europe,
List of protected areas of Bulgaria, is conserved in three national parks, 11 nature parks, 10 biosphere reserves and 565 protected areas. Ninety-three of the 233 mammal species of Europe are found in Bulgaria, along with 49% of butterfly and 30% of vascular plant species.
Overall, 41,493 plant and animal species are present.
Larger mammals with sizable populations include deer (106,323 individuals), wild boar (88,948), golden jackal (47,293) and red fox (32,326). Partridges number some 328,000 individuals, making them the most widespread Game (hunting), gamebird. A third of all nesting birds in Bulgaria can be found in Rila National Park, which also hosts Arctic and alpine species at high altitudes.
Flora includes more than 3,800 vascular plant species of which 170 are Endemism, endemic and 150 are considered endangered.
A checklist of larger fungi in Bulgaria by the Institute of Botany identifies more than 1,500 species. In Bulgaria forest cover is around 36% of the total land area, equivalent to 3,893,000 hectares (ha) of forest in 2020, up from 3,327,000 hectares (ha) in 1990. In 2020, naturally regenerating forest covered 3,116,000 hectares (ha) and planted forest covered 777,000 hectares (ha). Of the naturally regenerating forest 18% was reported to be primary forest (consisting of native tree species with no clearly visible indications of human activity) and around 18% of the forest area was found within protected areas. For the year 2015, 88% of the forest area was reported to be under State ownership, public ownership and 12% Private property, private ownership.

In 1998, the Bulgarian government adopted the National Biological Diversity Conservation Strategy, a comprehensive programme seeking the preservation of local ecosystems, protection of endangered species and conservation of genetic resources. Bulgaria has some of the largest Natura 2000 areas in Europe covering 33.8% of its territory. It also achieved its Kyoto Protocol objective of reducing carbon dioxide emissions by 30% from 1990 to 2009.
Bulgaria ranks 37th in the 2024 Environmental Performance Index, but scores low on air quality. Particulates, Particulate levels are the highest in Europe, especially in urban areas affected by automobile traffic and coal-based power stations. One of these, the lignite-fired Maritsa Iztok Complex, Maritsa Iztok-2 station, is causing the highest damage to health and the environment in the European Union.
Pesticide use in agriculture and antiquated industrial sewage systems produce extensive soil and water pollution.
Water quality began to improve in 1998 and has maintained a trend of moderate improvement. Over 75% of surface rivers meet European standards for good quality.
Politics
Bulgaria is a parliamentary democracy where the Prime Minister of Bulgaria, prime minister is the head of government and the most powerful executive position. The political system has three branches—legislative, executive and judicial, with universal suffrage for citizens at least 18 years old. The Constitution of Bulgaria, Constitution also provides possibilities of direct democracy, namely petitions and national referendums.
Elections are supervised by an independent Central Election Commission that includes members from all major political parties. Parties must register with the commission prior to participating in a national election. Normally, the prime minister-elect is the leader of the party receiving the most votes in parliamentary elections, although this is not always the case.
Unlike the prime minister, presidential domestic power is more limited. The directly elected President of Bulgaria, president serves as head of state and commander-in-chief of the armed forces, and has the authority to return a bill for further debate, although the parliament can override the presidential veto by a simple majority vote. Political parties gather in the National Assembly (Bulgaria), National Assembly, a body of 240 deputies elected to four-year terms by direct popular vote. The National Assembly has the power to enact laws, approve the budget, schedule presidential elections, select and dismiss the prime minister and other ministers, declare war, deploy troops abroad, and ratify international treaties and agreements.
Overall, Bulgaria displays a pattern of unstable governments. Boyko Borisov, the leader of the centre-right, pro-EU party GERB, served three terms as prime minister between 2009 and 2021.
It won 2009 Bulgarian parliamentary election, the 2009 general election and formed a minority government, which resigned in February 2013 after Protests against the Borisov cabinet, nationwide protests over the low living standards, corruption and the perceived failure of the democratic system.
The subsequent Bulgarian parliamentary election, 2013, snap elections in May resulted in a narrow win for GERB, but the Bulgarian Socialist Party eventually formed a government led by Plamen Oresharski after Borisov failed to secure parliamentary support.
The Oresharski government resigned in July 2014 amid continuing 2013–14 Bulgarian protests against the Oresharski cabinet, large-scale protests.
The 2014 Bulgarian parliamentary election, October 2014 elections resulted in a third GERB victory. Borisov Second Borisov Government, formed a coalition with several right-wing parties, but resigned again after the candidate backed by his party failed to win the Bulgarian presidential election, 2016, 2016 Presidential election. The Bulgarian parliamentary election, 2017, March 2017 snap election was again won by GERB, but with 95 seats in Parliament. They formed a coalition with the far-right United Patriots, who held 27 seats.
Borisov's last cabinet saw a dramatic decrease in freedom of the press, and a number of corruption revelations that triggered 2020–2021 Bulgarian protests, yet another wave of mass protests in 2020. GERB came out first in the regular April 2021 Bulgarian parliamentary election, April 2021 election, but with its weakest result so far. All other parties refused to form a government, and after a brief deadlock, another election was called July 2021 Bulgarian parliamentary election, for July 2021. It too failed to break the stalemate, as no political party was able to form a coalition government.
In April 2023, because of the political deadlock, Bulgaria held its fifth parliamentary 2023 Bulgarian parliamentary election, election since April 2021. GERB was the biggest, winning 69 seats. The bloc led by We Continue the Change won 64 seats in the 240-seat parliament. In June 2023, Prime Minister Nikolai Denkov formed a new coalition between We Continue The Change and GERB. According to the coalition agreement, Denkov will lead the government for the first nine months. He will be succeeded by former European Commissioner, Mariya Gabriel, of the GERB party. She was supposed to take over as prime minister in nine months.
Denkov resigned in accordance with the rotation agreement on 5 March 2024, to allow Gabriel to become the new Prime Minister. On 20 March 2024, the planned government rotation and signing of a renewed government failed due to disagreements between the two alliances on the cabinet and breaking down of relations. Negotiations ensued across to form a new government, but failed to produce any governments that could reach a majority support. GERB rejected the chance to form a government. PP–DB made a limited attempt to respect the original rotation agreement. The final chance to form a government, chosen by president Rumen Radev, went to ITN, which was immediately rejected.
On 29 March, as per Article 98 of the constitution, the President appointed the Chairman of the Chamber of Audit (Bulgaria), National Audit Office, Dimitar Glavchev, as the candidate for caretaker prime minister. He was granted a one-week deadline of until 6 April 2024 to propose the composition of the caretaker government.
Glavchev presented his proposal for the caretaker government on 5 April 2024, accepted by the President following negotiations and scheduling the election for 9 June 2024.
Glavchev and his cabinet were inaugurated on 9 April 2024 by the National Assembly.
The new elected 51st National Assembly of Bulgaria, 51st Parliament replaced the 50th National Assembly of Bulgaria, 50th Parliament when all elected members were sworn in on 11 November 2024.
After 11 voting rounds, Natalia Kiselova (BSP – United Left, BSP–OL) was elected as speaker of the National Assembly on 6 December 2024.
President Rumen Radev granted the October 2024 Bulgarian parliamentary election#First negotiation mandate, first negotiation mandate to the largest party GERB-SDS on 15 January 2025,
which formed a minority government alongside Bulgarian Socialist Party, BSP and There is Such a People, ITN, with support from Alliance for Rights and Freedoms, APS (Dogan). The government is led by GERB politician Rosen Zhelyazkov.

Economy

Bulgaria has an open, Economy of Bulgaria, high-income range market economy where the private sector accounts for more than 70% of Gross domestic product, GDP. From a largely agricultural country with a predominantly rural population in 1948, by the 1980s Bulgaria had transformed into an industrial economy, with scientific and technological research at the top of its budgetary expenditure priorities. The loss of COMECON markets in 1990 and the subsequent "Shock therapy (economics), shock therapy" of the Planned economy, planned system caused a steep decline in industrial and agricultural production, ultimately followed by an economic collapse in 1997.
The economy largely recovered during a period of rapid growth several years later,
but the average salary of 2,072 leva ($1,142) per month remains the lowest in the EU.
A balanced budget was achieved in 2003 and the country began running a budget surplus, surplus the following year.

Government procurement in particular is a critical area in corruption risk. An estimated 10 billion leva ($5.99 billion) of state budget and Structural Funds and Cohesion Fund, European cohesion funds are spent on public tenders each year; nearly 14 billion ($8.38 billion) were spent on public contracts in 2017 alone.

Most of the exports are manufactured goods, machinery, chemicals, fuel products and food. Two-thirds of food and agricultural exports go to OECD countries.
Although cereal and vegetable output dropped by 40% between 1990 and 2008, output in grains has since increased, and the 2016–2017 season registered the biggest grain output in a decade.

Bulgaria was ranked 38th in the Global Innovation Index in 2024. Chronic government underinvestment in research since 1990 has forced many professionals in science and engineering to leave Bulgaria.

Despite the lack of funding, research in chemistry, materials science and physics remains strong.
Antarctic research is actively carried out through the St. Kliment Ohridski Base on Livingston Island in Western Antarctica. The information and communication technologies (ICT) sector generates three per cent of economic output and employs 40,000 to 51,000 software engineers. Bulgaria was known as a "Communist Silicon Valley" during the Soviet era due to its key role in COMECON computing technology production. A concerted effort by the communist government to teach computing and IT skills in schools also indirectly made Bulgaria a major source of computer viruses in the 1980s and 90s. The country is a regional leader in supercomputer, high performance computing: it operates ''Avitohol'', the most powerful supercomputer in Southeast Europe, and will host one of the eight petascale computing, petascale European High-Performance Computing Joint Undertaking, EuroHPC supercomputers.

Another lunar mission, SpaceIL's ''Beresheet'', was also equipped with a Bulgarian-manufactured imaging payload. Bulgaria's first Geosynchronous satellite, geostationary communications satellite—BulgariaSat-1—was launched by SpaceX in 2017.
Infrastructure

Telephone services are widely available, and a central digital trunk line connects most regions. Vivacom (BTC) serves more than 90% of fixed lines and is one of the three operators providing mobile services, along with Mtel (Bulgaria), A1 and Telenor (Bulgaria), Telenor. Internet penetration stood at 69.2% of the population aged 16–74 and 78.9% of households in 2020.
Bulgaria's strategic geographic location and well-developed energy sector make it a key European energy centre despite its lack of significant fossil fuel deposits. Thermal power plants generate 48.9% of electricity, followed by nuclear power from the Kozloduy Nuclear Power Plant, Kozloduy reactors (34.8%) and renewable energy, renewable sources (16.3%). Equipment for a second nuclear power station at Belene Nuclear Power Plant, Belene has been acquired, but the fate of the project remains uncertain.

Health
High death rates result from a combination of an ageing population, high numbers of people at risk of poverty, and a weak Health system, healthcare system. Over 80% of deaths are due to cancer and cardiovascular conditions; nearly a fifth of those are avoidable. Although healthcare in Bulgaria is nominally universal,
out-of-pocket expenses account for nearly half of all healthcare spending, significantly limiting access to medical care. Other problems disrupting care provision are the emigration of doctors due to low wages, understaffed and under-equipped regional hospitals, supply shortages and frequent changes to the basic service package for those insured. The 2018 Bloomberg Health Care Efficiency Index ranked Bulgaria last out of 56 countries. Average life expectancy is 74.8 years, compared with an EU average of 80.99 and a world average of 72.38.
