Romania

Romania derives from the local name for Romanian (Romanian: român), which in turn derives from Latin romanus, meaning "Roman" or "of Rome". This ethnonym for Romanians is first attested in the sixteenth century by Italian humanists travelling in Transylvania, Moldavia, and Wallachia. The oldest known surviving document written in Romanian that can be precisely dated, a 1521 letter known as the "Letter of Neacșu from Câmpulung", is notable for including the first documented occurrence of Romanian in a country name: Wallachia is mentioned as Țara Rumânească.

=== Prehistory ===

Human remains found in Peștera cu Oase ("Cave with Bones"), radiocarbon date from circa 40,000 years ago, and represent the oldest known Homo sapiens in Europe. Neolithic agriculture spread after the arrival of a mixed group of people from Thessaly in the 6th millennium BC. Excavations at the Poiana Slatinei site near a salt spring next to Lunca, Neamț yielded the earliest evidence for salt exploitation in Europe; here salt production began between the 5th and 4th millennium BC. The first permanent settlements developed into "proto-cities", which were larger than 320 hectares (800 acres). The Cucuteni–Trypillia culture—the best known archaeological culture of Old Europe—flourished in Muntenia, southeastern Transylvania and northeastern Moldavia in the 3rd millennium BC.

The first fortified settlements appeared around 1800 BC, showing the militant character of Bronze Age societies.

Greek colonies established on the Black Sea coast in the 7th century BC became important centres of commerce with the local tribes. Among the native peoples, Herodotus listed the Getae of the Lower Danube region, the Agathyrsi of Transylvania and the Syginnae of the plains along the river Tisza at the beginning of the 5th century BC. Centuries later, Strabo associated the Getae with the Dacians who dominated the lands along the southern Carpathian Mountains in the 1st century BC. Burebista was the first Dacian ruler to unite the local tribes. He also conquered the Greek colonies in Dobruja and the neighbouring peoples as far as the Middle Danube and the Balkan Mountains between around 55 and 44 BC. After Burebista was murdered in 44 BC, his kingdom collapsed.

The Romans reached Dacia during Burebista's reign and conquered Dobruja in 46 AD. Dacia was again united under Decebalus around 85 AD. He resisted the Romans for decades, but the Roman army defeated his troops in 106 AD. Emperor Trajan transformed Banat, Oltenia and the greater part of Transylvania into a new province called Roman Dacia, but Dacian, Germanic and Sarmatian tribes continued to dominate the lands along the Roman frontiers. The Romans pursued an organised colonisation policy, and the provincials enjoyed a long period of peace and prosperity in the 2nd century. Scholars accepting the Daco-Roman continuity theory—one of the main theories about the origin of the Romanians—say that the cohabitation of the native Dacians and the Roman colonists in Roman Dacia was the first phase of the Romanians' ethnogenesis. The Carpians, Goths and other neighbouring tribes made regular raids against Dacia from the 210s. The Romans could not resist, and Emperor Aurelian ordered the evacuation of the province Dacia Trajana in the 270s. Scholars supporting the continuity theory are convinced that most Latin-speaking commoners stayed behind when the army and civil administration was withdrawn. The Romans did not abandon their fortresses along the northern banks of the Lower Danube for decades, and Dobruja (known as Scythia Minor) remained an integral part of the Roman Empire until the early 7th century.

The Goths were expanding towards the Lower Danube from the 230s, forcing the native peoples to flee to the Roman Empire or to accept their suzerainty. The Goths' rule ended abruptly when the Huns invaded their territory in 376, causing new waves of migrations. The Huns forced the remnants of the local population into submission, but their empire collapsed in 454. The Gepids took possession of the former Dacia province. Place names that are of Slavic origin abound in Romania, indicating that a significant Slavic-speaking population lived in the territory. The first Slavic groups settled in Moldavia and Wallachia in the 6th century, in Transylvania around 600. The nomadic Avars defeated the Gepids and established a powerful empire around 570. The Bulgars, who also came from the European Pontic steppe, occupied the Lower Danube region in 680.

After the Avar Khaganate collapsed in the 790s, the First Bulgarian Empire became the dominant power of the region, occupying lands as far as the river Tisa. The First Bulgarian Empire had a mixed population consisting of the Bulgar conquerors, Slavs and Vlachs (or Romanians) but the Slavicisation of the Bulgar elite had already begun in the 9th century. Following the conquest of southern Transylvania around 830, people from the Bulgar Empire mined salt at the local salt mines. The Council of Preslav declared Old Church Slavonic the language of liturgy in the country in 893. The Vlachs also adopted Old Church Slavonic as their liturgical language.

The Magyars (or Hungarians) took control of the steppes north of the Lower Danube in the 830s, but the Bulgarians and the Pechenegs forced them to abandon this region for the lowlands along the Middle Danube around 894. Centuries later, the Gesta Hungarorum wrote of the invading Magyars' wars against three dukes—Glad, Menumorut and the Vlach Gelou—for Banat, Crișana and Transylvania. The Gesta also listed many peoples—Slavs, Bulgarians, Vlachs, Khazars, and Székelys—inhabiting the same regions. The reliability of the Gesta is debated. Some scholars regard it as a basically accurate account, others describe it as a literary work filled with invented details. The Pechenegs seized the lowlands abandoned by the Hungarians to the east of the Carpathians.

Byzantine missionaries proselytised in the lands east of the Tisa from the 940s and Byzantine troops occupied Dobruja in the 970s. The first king of Hungary, Stephen I, who supported Western European missionaries, defeated the local chieftains and established Roman Catholic bishoprics (office of a bishop) in Transylvania and Banat in the early 11th century. Significant Pecheneg groups fled to the Byzantine Empire in the 1040s; the Oghuz Turks followed them, and the nomadic Cumans became the dominant power of the steppes in the 1060s. Cooperation between the Cumans and the Vlachs against the Byzantine Empire is well documented from the end of the 11th century. Scholars who reject the Daco-Roman continuity theory say that the first Vlach groups left their Balkan homeland for the mountain pastures of the eastern and southern Carpathians in the 11th century, establishing the Romanians' presence in the lands to the north of the Lower Danube.

Exposed to nomadic incursions, Transylvania developed into an important border province of the Kingdom of Hungary. The Székelys—a community of free warriors—settled in central Transylvania around 1100 and moved to the easternmost regions around 1200. Colonists from the Holy Roman Empire—the Transylvanian Saxons' ancestors—came to the province in the 1150s. A high-ranking royal official, styled voivode, ruled the Transylvanian counties from the 1170s, but the Székely and Saxon seats (or districts) were not subject to the voivodes' authority. Royal charters wrote of the "Vlachs' land" in southern Transylvania in the early 13th century, indicating the existence of autonomous Romanian communities. Papal correspondence mentions the activities of Orthodox prelates among the Romanians in Muntenia in the 1230s. Also in the 13th century, the Republic of Genoa started establishing colonies on the Black Sea, including Calafat, and Constanța.

The Mongols destroyed large territories during their invasion of Eastern and Central Europe in 1241 and 1242. The Mongols' Golden Horde emerged as the dominant power of Eastern Europe, but Béla IV of Hungary's land grant to the Knights Hospitallers in Oltenia and Muntenia shows that the local Vlach rulers were subject to the king's authority in 1247. Basarab I of Wallachia united the Romanian polities between the southern Carpathians and the Lower Danube in the 1310s. He defeated the Hungarian royal army in the Battle of Posada and secured the independence of Wallachia in 1330. The second Romanian principality, Moldavia, achieved full autonomy during the reign of Bogdan I around 1360. A local dynasty ruled the Despotate of Dobruja in the second half of the 14th century, but the Ottoman Empire took possession of the territory after 1388.

Princes Mircea I and Vlad III of Wallachia, and Stephen III of Moldavia defended their countries' independence against the Ottomans. Most Wallachian and Moldavian princes paid a regular tribute to the Ottoman sultans from 1417 and 1456, respectively. John Hunyadi, organised the defence of the Kingdom of Hungary and anti-Ottoman campaigns from 1440 until his death in 1456. Increasing taxes outraged the Transylvanian peasants, and they rose up in an open rebellion in 1437, but the Hungarian nobles and the heads of the Saxon and Székely communities jointly suppressed their revolt. The formal alliance of the Hungarian, Saxon, and Székely leaders, known as the Union of the Three Nations, became an important element of the self-government of Transylvania. The Orthodox Romanian knezes ("chiefs") were excluded from the Union.

The Kingdom of Hungary collapsed, and the Ottomans occupied parts of Banat and Crișana in 1541. Transylvania and Maramureș, along with the rest of Banat and Crișana, developed into a new state under Ottoman suzerainty, the Principality of Transylvania. The Reformation, initiated in Germany by Martin Luther in 1517, encouraged the spread of Protestantism across the region; by 1568, the Edict of Torda formally granted local communities the right to choose their own preachers, sanctioning the existence of four "received" religions (Catholicism, Lutheranism, Calvinism, and Unitarianism). The Romanians' Orthodox faith remained only tolerated, although they made up more than one-third of the population, according to 17th-century estimates. In June 1609, Gabriel Báthory freed the Romanian Orthodox clergy from both taxation and service demands.

The princes of Transylvania, Wallachia, and Moldavia joined the Holy League against the Ottoman Empire in 1594. The Wallachian prince, Michael the Brave, united the three principalities under his rule in May 1600. The neighbouring powers forced him to abdicate in September, but he became a symbol of the unification of the Romanian lands in the 19th century. Although the rulers of the three principalities continued to pay tribute to the Ottomans, the most talented princes—Gabriel Bethlen of Transylvania, Matei Basarab of Wallachia, and Vasile Lupu of Moldavia—strengthened their autonomy.

The united armies of the Holy League expelled the Ottoman troops from Central Europe between 1684 and 1699, and the Principality of Transylvania was integrated into the Habsburg monarchy. The Habsburgs supported the Catholic clergy and persuaded the Orthodox Romanian prelates to accept the union with the Roman Catholic Church in 1699. In the 18th century, Moldavia and Wallachia maintained their internal autonomy, but in 1711 and 1716, respectively, the period of the Phanariots began, with rulers appointed directly by the Porte from among the noble families of Greek origin in Constantinople. With the signing of the Ausgleich in 1867, Transylvania quickly lost its remaining political autonomy, being politically and administratively incorporated into the Kingdom of Hungary. The Church Union strengthened the Romanian intellectuals' devotion to their Roman heritage. The Orthodox Church was restored in Transylvania only after Orthodox monks stirred up revolts in 1744 and 1759. The organisation of the Transylvanian Military Frontier caused further disturbances, especially among the Székelys in 1764.

Princes Dimitrie Cantemir of Moldavia and Constantin Brâncoveanu of Wallachia concluded alliances with the Habsburg Monarchy and Russia against the Ottomans, but they were dethroned in 1711 and 1714, respectively. The sultans lost confidence in the native princes and appointed Orthodox merchants from the Phanar district of Istanbul to rule Moldavia and Wallachia. The Phanariot princes pursued oppressive fiscal policies and dissolved the army. The neighbouring powers took advantage of the situation: the Habsburg Monarchy annexed the northwestern part of Moldavia, or Bukovina, in 1775, and the Russian Empire seized the eastern half of Moldavia, or Bessarabia, in 1812.

A census revealed that the Romanians were more numerous than any other ethnic group in Transylvania in 1733, but legislation continued to use contemptuous adjectives (such as "tolerated" and "admitted") when referring to them. The Uniate bishop, Inocențiu Micu-Klein, who demanded recognition of the Romanians as the fourth privileged nation, was forced into exile. Uniate and Orthodox clerics and laymen jointly signed a plea for the Transylvanian Romanians' emancipation in 1791, but the monarch and the local authorities refused to grant their requests.

The Treaty of Küçük Kaynarca authorised the Russian ambassador in Istanbul to defend the autonomy of Moldavia and Wallachia (known as the Danubian Principalities) in 1774. Taking advantage of the Greek War of Independence, a Wallachian lesser nobleman, Tudor Vladimirescu, stirred up a revolt against the Ottomans in January 1821, but he was murdered in June by Phanariot Greeks. After a new Russo-Turkish War, the Treaty of Adrianople strengthened the autonomy of the Danubian Principalities in 1829, although it also acknowledged the sultan's right to confirm the election of the princes.

Mihail Kogălniceanu, Nicolae Bălcescu and other leaders of the 1848 revolutions in Moldavia and Wallachia demanded the emancipation of the peasants and the union of the two principalities, but Russian and Ottoman troops crushed their revolt. The Wallachian revolutionaries were the first to adopt the blue, yellow and red tricolour as the national flag, which included the motto "Justice, Fraternity" (Dreptate, Frăție) to symbolise the bond between Wallachians and Moldavians. In Transylvania, most Romanians supported the imperial government against the Hungarian revolutionaries after the Diet passed a law concerning the union of Transylvania and Hungary. Bishop Andrei Șaguna proposed the unification of the Romanians of the Habsburg Monarchy in a separate duchy, but the central government refused to change the internal borders.

==== From the Little Union to the Great War ====

The modern Romanian state was created through the unification of the principalities of Moldavia and Wallachia, accepted as a federative structure by the Great Powers following the Paris Convention of 1858, and later cemented by the simultaneous election as ruler of both states of the unionist Alexandru Ioan Cuza. After carrying out numerous reforms that laid the foundations for the modernisation of the state, he was forced in 1866 by a broad coalition of the political parties of the time, also known as the "Monstrous coalition", to abdicate and leave the country.

The union was at one time in peril, but the political leaders of the era succeeded in placing on the princely throne Carol I of Romania, who accepted the Constitution and took the oath on 10 May 1866. Eleven years later, on 10 May 1877, Romania proclaimed its independence—achieved on the battlefield—and in 1881, on the same day of the year, Carol was crowned as King of Romania. In 1913, Romania entered the Second Balkan War against Bulgaria, at the end of which it obtained Southern Dobruja. In 1914, King Carol I died, and his nephew, Ferdinand I, succeeded him on the throne.

In 1916, Romania entered World War I on the side of the Entente Powers. Although the Romanian forces did not perform well militarily, by the end of the war the Austrian and Russian Empires had disintegrated; the National Assembly in Transylvania, and the Sfatul Țării in Bessarabia and Bukovina proclaimed their union with Romania, and King Ferdinand I and Queen Maria were crowned sovereign of all Romanians in Alba Iulia on 15 October 1922.

After World War I, the union of Bukovina with Romania was ratified in 1919 by the Treaty of Saint Germain. Most of the territories claimed by Romania from the Kingdom of Hungary—Crișana, Transylvania and parts of Banat and Maramureș—were annexed to the Kingdom of Romania. This act was ratified in 1920 by the Treaty of Trianon, which defined the new border between Hungary and Romania.

After having left the country and renounced his claim to the throne in 1925, Carol II returned in 1930 and usurped his son's throne; influenced by his inner circle—referred to by historians as the "Royal Camarilla"—he gradually undermined the democratic system, and in 1938 he assumed dictatorial powers. Although he was pro-Western (especially Anglophile), Carol attempted to appease extreme centrifugal forces by appointing nationalist governments that adopted anti-Semitic measures, such as the Goga cabinet and the one led by the Orthodox Patriarch Miron Cristea.

Following the Molotov–Ribbentrop Pact of 1939, in June 1940 Romania accepted the loss of Bessarabia, Northern Bukovina and the Hertsa region in favour of the USSR (as stipulated in the Soviet ultimatum of 28 June 1940). Unaware of the details of the Soviet–German pact, Carol attempted to secure an alliance with Nazi Germany, and appointed Ion Gigurtu as President of the Council of Ministers, who declared that he would pursue a Nazi pro-Axis (Berlin–Rome) policy that was anti-Semitic and fascist-totalitarian in nature. Between 4 July and 4 September 1940, by accepting Hitler's arbitration over Transylvania (after Gigurtu declared on radio that Romania must make territorial sacrifices to justify its Nazi orientation and full adherence to the Berlin–Rome Axis), Romania ceded Northern Transylvania—including the city of Cluj—to Hungary. The vast territories in Transylvania ceded by Ion Gigurtu to Hungary contained important natural resources, including gold mines. Ion Gigurtu also initiated negotiations to cede 8,000 km2 of Southern Dobruja to Bulgaria, these negotiations were interrupted by Antonescu's unconditional acceptance of the territorial cession.

In response to the chaotic withdrawal from Bessarabia, the territorial cessions, public discontent, and protests from political leaders, King Carol II suspended the 1938 Constitution of Romania and appointed General Ion Antonescu as Prime Minister. This measure, supported by the Iron Guard, demanded that the king abdicate in favour of his son, Mihai. Subsequently, Antonescu assumed dictatorial powers and became President of the Council of Ministers, as the self-titled "Leader" of the state.

In 1941, as an ally of Nazi Germany, Romania entered World War II by declaring war on the Soviet Union. A shift in fortunes only became discernible after the defeat at Stalingrad and the subsequent change of the USSR from a defensive to an offensive posture. On 23 August 1944, with the Soviet army having been present in northern Moldova since March, King Mihai I forcibly removed Marshal Ion Antonescu from power, as he refused to sign an armistice with the Allies of World War II. Following Antonescu's outright refusal, King Mihai I ordered the dismissal and arrest of the marshal, and Romania switched sides to join the Allies.

Less than three years after the Soviet occupation of Romania, in 1947, King Michael I was forced to abdicate and the People's Republic of Romania—a state of "popular democracy"—was proclaimed. The newly established communist regime, led by the Romanian Workers' Party, consolidated its power through a Stalinist-type policy aimed at suppressing any political opposition and transforming the economic and social structures of the old bourgeois regime.

In the early 1960s, the Romanian government began asserting a certain degree of independence from the Soviet Union in its foreign policy, although it did not abandon its repressive policies (which it labelled "revolutionary conquests") in domestic affairs. In 1965, communist leader Gheorghe Gheorghiu-Dej died, ushering in a period of change in Romania. After a brief power struggle, Nicolae Ceaușescu emerged as the head of the communist party, becoming General Secretary of the Romanian Communist Party in 1965, President of the State Council in 1967, and President of the Socialist Republic of Romania in 1974. Ceaușescu's rule from 1965 to 1989 grew increasingly authoritarian during the 1980s.

In the context of the fall of communism throughout Eastern Europe during the revolutions of 1989, a protest in support of Reformed pastor László Tőkés that began in December 1989 in Timișoara quickly escalated into a national uprising against the communist regime, ultimately resulting in the execution of Ceaușescu and his wife Elena on 25 December 1989.

An interim council composed of figures from civil society and former communist officials assumed control of the government, and Ion Iliescu became the provisional president of the country. The new government reversed many of the authoritarian communist policies and dismissed several leaders of the former regime, although still influenced by members of the former regime (the basis for the Golaniad, and Mineriads).

In May 1990, the first free elections in Romania since the 1937 elections were held, with Iliescu of the National Salvation Front winning the presidency with 85% of the vote. In 1992, he was reelected in the first election after the adoption of a permanent constitution via a referendum held the previous year. Illiescu lost the 1996 election to Emil Constantinescu, but returned to power in 2000. Traian Băsescu was elected president in 2004 and 2009, serving until 2014 at which point Klaus Iohannis succeeded him, being re-elected in 2019 and serving until 2025. During these years several events occurred. In 2009, the country was bailed out by the International Monetary Fund as result of the Great Recession in Europe following the 2008 financial crisis.

The post-1989 period has been characterised by the privatisation and closure of several former industrial and economic enterprises from the communist period, while corruption has been a major issue in contemporary politics.

A National Anticorruption Directorate was formed in the country in 2002. During the 2000s, Romania had one of the highest economic growth rates in Europe and has been referred at times as "the Tiger of Eastern Europe". This has been accompanied by a significant improvement in living standards as the country successfully reduced domestic poverty and established a functional democratic state. However, Romania's development suffered a major setback during the late 2000s' recession leading to a large gross domestic product contraction and a budget deficit in 2009. This led to Romania borrowing from the International Monetary Fund. Worsening economic conditions led to unrest and triggered a political crisis in 2012.

Since 2014, Romania launched an anti-corruption effort that led to the prosecution of medium- and high-level political, judicial and administrative offences by the National Anticorruption Directorate. In 2015, massive anti-corruption protests which developed in the wake of the Colectiv nightclub fire led to the resignation of prime minister Victor Ponta. During 2017–2019, in response to measures which were perceived to weaken the fight against corruption, some of the biggest post-1989 protests took place in Romania, with over 500,000 people protesting nationwide.

The 2021 Romanian political crisis led to the ousting of Florin Cîțu's incumbent government. The Ciucă Cabinet then took power, with Romania since having experienced a shift towards authoritarianism and illiberalism, as well as an increased corruption. Around this time, Romania was also hit by the COVID-19 pandemic. In the 2024 presidential election, Independent candidate Călin Georgescu achieved a surprise win in the first round. However, the Constitutional Court annulled the election results, citing Russian meddling. The cancellation led to far-right protests, criticism by the Trump administration, and Ilie Bolojan becoming acting president in February 2025 as Iohannis resigned to political pressure. In the subsequent 2025 Romanian presidential election, Bucharest Mayor Nicușor Dan was elected president.

Romania is the largest country in Southeastern Europe and the twelfth-largest in Europe, having an area of 238,397 square kilometres (92,046 sq mi). It lies between latitudes 43° and 49° N and longitudes 20° and 30° E. The terrain is distributed roughly equally between mountains, hills, and plains. The Carpathian Mountains dominate the centre of Romania, with 14 mountain ranges reaching above 2,000 m or 6,600 ft—the highest is Moldoveanu Peak at 2,544 m or 8,346 ft. They are surrounded by the Moldavian and Transylvanian plateaus, the Pannonian Plain and the Wallachian plains.

Romania is home to six terrestrial ecoregions: Balkan mixed forests, Central European mixed forests, East European forest steppe, Pannonian mixed forests, Carpathian montane conifer forests, and Pontic steppe. Natural and semi-natural ecosystems cover about 47% of the country's land area. There are almost 10,000 km2 (3,900 sq mi) (about 5% of the total area) of protected areas in Romania covering 13 national parks and three biosphere reserves. The Danube river forms a large part of the border with Serbia and Bulgaria, and flows into the Black Sea, forming the Danube Delta, which is the second-largest and best-preserved delta in Europe, and a biosphere reserve and a biodiversity World Heritage Site. At 5,800 km2 (2,200 sq mi), the Danube Delta is the largest continuous marshland in Europe, and supports 1,688 different plant species alone.

Romania has one of the largest areas of undisturbed forest in Europe, covering almost 27% of its territory. The country had a 2019 Forest Landscape Integrity Index mean score of 5.95/10, ranking it 90th globally out of 172 countries. Some 3,700 plant species have been identified in the country, from which to date 23 have been declared natural monuments, 74 extinct, 39 endangered, 171 vulnerable, and 1,253 rare.

The fauna of Romania consists of 33,792 species of animals, 33,085 invertebrate and 707 vertebrate, with almost 400 unique species of mammals, birds, reptiles, and amphibians, including about 50% of Europe's (excluding Russia) brown bears and 20% of its wolves.

Romania is often seen by most as having the shape resembling one of a goldfish.

Owing to its distance from open sea and its position on the southeastern portion of the European continent, Romania has a climate that is continental, with four distinct seasons. The average annual temperature is 11 °C (52 °F) in the south and 8 °C (46 °F) in the north. In summer, average maximum temperatures in Bucharest rise to 28 °C (82 °F), and temperatures over 35 °C (95 °F) are fairly common in the lower-lying areas of the country. In winter, the average maximum temperature is below 2 °C (36 °F). Precipitation is average, with over 750 mm (30 in) per year only on the highest western mountains, while around Bucharest it drops to approximately 570 mm (22 in).

There are some regional differences: in western sections, such as Banat, the climate is milder and has some Mediterranean influences; the eastern part of the country has a more pronounced continental climate. In Dobruja, the Black Sea also exerts an influence over the region's climate.

Romania is a unitary semi-presidential representative democratic republic with a structured system of governance and an active civil society. The President, elected by popular vote, serves as the head of state, representing the country in international affairs, safeguarding constitutional order, and acting as supreme commander of the Romanian Armed Forces. The Prime Minister, appointed by the President and confirmed by the Parliament, acts as the head of government, responsible for overseeing the executive branch, implementing domestic and foreign policies, and managing public administration. Legislative authority is vested in a bicameral Parliament, consisting of the Chamber of Deputies and the Senate, whose members are elected through a proportional representation system. The judiciary operates independently, with the High Court of Cassation and Justice as the highest court of appeal.

According to International IDEA's Global State of Democracy (GSoD) Indices and Democracy Tracker, Romania performs in the mid- range on overall democratic measures, with particular strengths in inclusive suffrage and elected government.

Romania has a democratic, multi-party system, with legislative power vested in the government and the two chambers of the Parliament, more specifically the Chamber of Deputies and the Senate. The judiciary is independent of the executive and the legislature. The latter is elected by popular vote for a maximum of two terms of five years and appoints the prime minister who in turn appoints the Council of Ministers. The legislative branch of the government, collectively known as the Parliament (residing at the Palace of the Parliament), consists of two chambers (Senate and Chamber of Deputies) whose members are elected every four years by simple plurality.

The justice system is independent of the other branches of government and is made up of a hierarchical system of courts with the High Court of Cassation and Justice being the supreme court of Romania. There are also courts of appeal, county courts and local courts. The Romanian judicial system is strongly influenced by the French model, is based on civil law and is inquisitorial in nature. The Constitutional Court (Curtea Constituțională) is responsible for judging the compliance of laws and other state regulations with the constitution, which is the fundamental law of the country and can be amended only through a public referendum. Romania's 2007 entry into the EU has been a significant influence on its domestic policy, and including judicial reforms, increased judicial cooperation with other member states, and measures to combat corruption. The Economist Intelligence Unit rated Romania as a "flawed democracy" in 2025.

Romania is divided into 41 counties (județe) and the municipality of Bucharest. Each county is administered by a county council, responsible for local affairs, as well as a prefect responsible for the administration of national affairs at the county level. The prefect is appointed by the central government but cannot be a member of any political party. Each county is subdivided further into cities and communes, which have their own mayor and local council. There are a total of 320 cities and 2,861 communes in Romania. A total of 103 of the larger cities have municipality status, which gives them greater administrative power over local affairs. The municipality of Bucharest is a special case, as it enjoys a status on par to that of a county. It is further divided into six sectors and has a prefect, a general mayor (primar general), and a general city council.

The NUTS-3 (Nomenclature of Territorial Units for Statistics) level divisions of the EU reflect Romania's administrative-territorial structure and correspond to the 41 counties plus Bucharest. The cities and communes correspond to the NUTS-5 level divisions, but there are no current NUTS-4 level divisions. The NUTS-1 (four macroregions) and NUTS-2 (eight development regions) divisions exist but have no administrative capacity and are used instead for coordinating regional development projects and statistical purposes.
