Wallachia in the context of Principality

Romania is a country located at the crossroads of Central, Eastern and Southeast Europe. It borders Ukraine to the north and east, Hungary to the west, Serbia to the southwest, Bulgaria to the south, Moldova to the east, and the Black Sea to the southeast. It has a mainly continental climate, and an area of 238,397 km (92,046 sq mi) with a population of 19 million people. Romania is the twelfth-largest country in Europe and the sixth-most populous member state of the European Union. Europe's second-longest river, the Danube, empties into the Danube Delta in the southeast of the country. The Carpathian Mountains cross Romania from the north to the southwest and include Moldoveanu Peak, at an altitude of 2,544 m (8,346 ft). Bucharest is the country's capital, largest urban area, and financial centre. Other major urban areas include Cluj-Napoca, Timișoara, Iași, Constanța and Brașov.

Settlement in the territory of modern Romania began in the Lower Paleolithic, later becoming the Dacian Kingdom before Roman conquest and Romanisation. The modern Romanian state was formed in 1859 with the unification of Moldavia and Wallachia under Alexandru Ioan Cuza, becoming the Kingdom of Romania in 1881 under Carol I of Romania. Romania gained independence from the Ottoman Empire in 1877, formalised by the Treaty of Berlin. After World War I, Transylvania, Banat, Bukovina, and Bessarabia joined the Old Kingdom, forming Greater Romania, which reached its largest territorial extent. In 1940, under Axis pressure, Romania lost territories to Hungary, Bulgaria, and the Soviet Union. Following the 1944 Romanian coup d'état, Romania switched sides to join the Allies. After World War II, it regained Northern Transylvania through the Paris Peace Treaties. Under Soviet occupation, King Michael I was forced to abdicate, and Romania became a socialist republic and Warsaw Pact member. After the uniquely violent Romanian revolution in December 1989, Romania began a transition to liberal democracy and a market economy.

Southern Europe is also known as Mediterranean Europe, as its geography is marked by the Mediterranean Sea. Definitions of southern Europe include some or all of these countries and regions: Albania, Andorra, Bosnia and Herzegovina, Bulgaria, Croatia, Cyprus, Gibraltar, Greece, Italy, Kosovo, Malta, Monaco, Montenegro, North Macedonia, Portugal, San Marino, Serbia, Slovenia, southern France, southern Romania, Spain, Ticino (Switzerland), Turkey, and Vatican City.

Southern Europe is focused on the three peninsulas located in the extreme south of the European continent. These are the Iberian Peninsula, the Italian Peninsula, and the Balkan Peninsula. These three peninsulas are separated from the rest of Europe by towering mountain ranges, respectively by the Pyrenees, the Alps and the Balkan Mountains. The location of these peninsulas in the heart of the Mediterranean Sea, as well as their mountainous reliefs, provide them with very different types of climates (mainly subtropical Mediterranean) from the rest of the continent. So, the Sirocco hot wind that originates in the heart of the Sahara blows over Italy, going up to the interior of the Alpine arc (Po Valley). The Alps prevent the Sirocco from spreading to the rest of Europe. And, conversely, the Alps and the Pyrenees protect the Italian and Iberian Peninsulas from the rains and icy winds from the south of France such as the Mistral and the Tramontane. When the Mistral and the Tramontane are blowing, this provokes an "upwelling" phenomenon on the French coast. They push the surface waters out to sea and bring deeper, cooler waters up to the seaside. Consequently, the temperature of the waters of the French coasts are therefore very cool even in summer, and not representative of the rest of the Mediterranean.This same kind of phenomenon takes place between the two slopes of the Balkan mountain range. These mountains have, moreover, been a serious handicap to population displacement, focusing southern Europe mainly on the Mediterranean world. The climate and cultures are therefore very specific.

Moldova, officially the Republic of Moldova, is a landlocked country in Eastern Europe, with an area of 33,843 km (13,067 sq mi) and a population of 2.38 million. Moldova is bordered by Romania to the west and Ukraine to the north, east, and south. The unrecognised breakaway state of Transnistria lies across the Dniester river on the country's eastern border with Ukraine. Moldova is a unitary parliamentary representative democratic republic with its capital in Chișinău, the country's largest city and main cultural and commercial centre.

Most of Moldovan territory was a part of the Principality of Moldavia from the 14th century until 1812, when it was ceded to the Russian Empire by the Ottoman Empire (to which Moldavia was a vassal state) and became known as Bessarabia. In 1856, southern Bessarabia was returned to Moldavia, which three years later united with Wallachia to form Romania. Still, Russian rule was restored over the entire region in 1878. During the 1917 Russian Revolution, Bessarabia briefly became an autonomous state within the Russian Republic. In February 1918, it declared independence and then integrated into Romania later that year following a vote of its assembly. The decision was disputed by Soviet Russia, which in 1924 established, within the Ukrainian SSR, a so-called Moldavian autonomous republic on partially Moldovan-inhabited territories to the east of Bessarabia. In 1940, as a consequence of the Molotov–Ribbentrop Pact, Romania was compelled to cede Bessarabia and Northern Bukovina to the Soviet Union, leading to the creation of the Moldavian Soviet Socialist Republic (Moldavian SSR).

The Kingdom of Romania (Romanian: Regatul României) was a constitutional monarchy that existed from 25 March [O.S. 13 March] 1881 with the crowning of prince Karl of Hohenzollern-Sigmaringen as King Carol I (thus beginning the Romanian royal family), until 1947 with the abdication of King Michael I and the Romanian parliament's proclamation of the Romanian People's Republic.

From 1859 to 1877, Romania evolved from a personal union of two principalities: (Moldavia and Wallachia) called the Unification of Moldavia and Wallachia also known as "The Little Union" under a single prince to an autonomous principality with a Hohenzollern monarchy. The country gained its independence from the Ottoman Empire during the 1877–1878 Russo-Turkish War (known locally as the Romanian War of Independence), after which it was forced to cede the southern part of Bessarabia in exchange for Northern Dobruja. The kingdom's territory during the reign of King Carol I, between 13 (O.S.) / 25 March 1881 and 27 September (O.S.) / 10 October 1914 is sometimes referred to as the Romanian Old Kingdom, to distinguish it from "Greater Romania", which included the provinces that became part of the state after World War I (Bessarabia, Banat, Bukovina, and Transylvania).

Moldavia (Romanian: Moldova, pronounced [molˈdova] or Țara Moldovei lit. 'The country of Moldova'; in Romanian Cyrillic: Молдова or Цара Мѡлдовєй) is a historical region and former principality in Eastern Europe, corresponding to the territory between the Eastern Carpathians and the Dniester River. An initially independent and later autonomous state, it existed from the 14th century to 1859, when it united with Wallachia (Țara Românească) as the basis of the modern Romanian state; at various times, Moldavia included the regions of Bessarabia (with the Budjak), all of Bukovina and Hertsa. It also included the region of Pokuttya for a period of time.

The western half of Moldavia is now part of Romania, the eastern side belongs to the Republic of Moldova, and the northern and southeastern parts are territories of Ukraine.

Alexandru Ioan Cuza (Romanian: [alekˈsandru iˈo̯aŋ ˈkuza] , or Alexandru Ioan I, also Anglicised as Alexander John Cuza; 20 March [O.S. 8 March] 1820 – 15 May 1873) was the first domnitor (prince) of the Romanian Principalities through his double election as Prince of Moldavia on 5 January 1859 and Prince of Wallachia on 24 January 1859, which resulted in the unification of the two states. He was a prominent figure of the Moldavian Revolution of 1848. Following his double election, he initiated a series of liberal and progressive reforms that contributed to the modernization of Romanian society and of state structures.

As ruler of the Romanian Principalities, he supported a political and diplomatic activity for the recognition of the union of Moldavia and Wallachia by the suzerain Ottoman Empire and achieved constitutional and administrative unity between Moldavia and Wallachia in 1862, when the Romanian Principalities officially adopted the name Romanian United Principalities with a single capital at Bucharest, a single national assembly and a single government.

The Romanian Old Kingdom (Romanian: Vechiul Regat or just Regat; German: Regat or Altreich) is a colloquial term referring to the territory covered by the first independent Romanian nation state, which was composed of the Romanian Principalities: Wallachia and Moldavia. The union of the two principalities was achieved when, under the auspices of the Treaty of Paris (1856), the ad hoc Divans of both countries, which were then under Ottoman Empire suzerainty, voted for Alexander Ioan Cuza as their prince. This process achieved a de facto unification under the name of the United Principalities of Moldavia and Wallachia. The region itself is defined by the result of that political act, followed by the Romanian War of Independence, the inclusion of Northern Dobruja and the transfer of the southern part of Bessarabia to the Russian Empire in 1878, the proclamation of the Kingdom of Romania in 1881, and the annexation of Southern Dobruja in 1913.

The term came into use after World War I, when the Old Kingdom became Greater Romania, after including Transylvania, Banat, Bessarabia, and Bukovina. The term now has mainly a historical relevance and is otherwise used as a common term for all regions in Romania included in both the Old Kingdom and the present borders (Wallachia, Moldavia, and Northern Dobruja).

Romanian (obsolete spelling: Roumanian; endonym: limba română [ˈlimba roˈmɨnə] , or românește [romɨˈneʃte], lit. 'in Romanian') is the official and main language of Romania and Moldova. Romanian is part of the Eastern Romance sub-branch of Romance languages, a linguistic group that evolved from several dialects of Vulgar Latin which separated from the Western Romance languages in the course of the period from the 5th to the 8th centuries. To distinguish it within the Eastern Romance languages, in comparative linguistics it is called Daco-Romanian as opposed to its closest relatives, Aromanian, Megleno-Romanian, and Istro-Romanian. It is also spoken as a minority language by stable communities in the countries surrounding Romania (Bulgaria, Hungary, Serbia and Ukraine), and by the large Romanian diaspora. In total, it is spoken by 25 million people as a first language.

Romanian was also known as Moldovan in Moldova, although the Constitutional Court of Moldova ruled in 2013 that "the official language of Moldova is Romanian". On 16 March 2023, the Moldovan Parliament approved a law on referring to the national language as Romanian in all legislative texts and the constitution. On 22 March, the president of Moldova, Maia Sandu, promulgated the law.

The historical regions of Romania are located in Central, Southeastern, and Eastern Europe. Romania came into being through the unification of two principalities, Wallachia and Moldova in 1862. The new unitary state extended over further regions at various times during the late 19th and 20th centuries, including Dobruja in 1878, and Transylvania in 1918.

These regions are part of Romania today:

The United Principalities of Moldavia and Wallachia (Romanian: Principatele Unite ale Moldovei și Țării Românești), commonly called United Principalities or Wallachia and Moldavia, was the personal union of the Principality of Moldavia and the Principality of Wallachia. The union was formed on 5 February [O.S. 24 January] 1859 when Alexandru Ioan Cuza was elected as the Domnitor (Ruling Prince) of both principalities. Their separate autonomous vassalage in the Ottoman Empire continued with the unification of both principalities. On 3 February [O.S. 22 January] 1862, Moldavia and Wallachia formally united to create the Romanian United Principalities, the core of the Romanian nation state.

In February 1866, Prince Cuza was forced to abdicate and go into exile by a political coalition led by the Liberals; the German prince Karl of Hohenzollern-Sigmaringen was offered the throne and, on 22 May [O.S. 10 May] 1866 he entered Bucharest for the first time. In July the same year, a new constitution came into effect, giving the country the name of Romania; internationally, this name was used only after 1877, since at the time it shared a common foreign policy with the Ottoman Empire. Nominally, the new state remained a vassal of the Ottoman Empire. However, by this time the suzerainty of the Sublime Porte had become a legal fiction. Romania had its own flag and anthem; after 1867, it had its own currency as well.

The Danubian Principalities (German: Donaufürstentümer, Russian: Дунайские княжества, Romanian: Principatele Dunărene) was a geopolitical term used for the Ottoman vassal principalities of Moldavia and Wallachia in the period of 1774–1858, a time of when the territories were a battleground between the Ottoman Empire, Habsburg Monarchy, and Russian Empire. While Russia returned Moldavia and Wallachia to the Ottoman Empire with the Treaty of Küçük Kaynarca (1774), it retained protectorship over the two and also of the Orthodox subjects in all of the Ottoman Empire. This made the two principalities have the status of dual authority, under Ottoman suzerainty but with Russian protection. The Russo-Turkish War (1828–1829) ended with the Russian occupation of the two principalities. The negotiations of the Great Powers in the aftermath of Russian defeat resulted in the unification of Moldavia and Wallachia in 1859.

The siege of Silistria, or siege of Silistra, was a key engagement in the Crimean War, fought from 11 May to 23 June 1854 between the Russian Empire and the Ottoman Empire in present-day Bulgaria. The Russian army, numbering up to 90,000 men with 266 guns, attempted to capture the Danubian fortress of Silistria as part of a broader strategy to outflank Ottoman defences and pre-empt an expected Allied landing at Varna. The garrison, 12,000 to 18,000 Ottoman troops and Egyptian auxiliaries, was bolstered by British military advisers and successfully withstood a six-week siege.

The operation was shaped by diplomatic and regional tensions. Russia hoped for a general Balkan uprising and misjudged the likelihood of Austrian or Serbian neutrality. Austria, concerned that a Russian advance might provoke unrest among its own Serb population, mobilised 280,000 troops along the Danube and warned Russia against crossing the river. At the same time, Anglo-French troops began arriving in Varna, and a joint Austrian–Ottoman convention granted Austria the right to occupy the Danubian Principalities of Wallachia and Moldavia.

An ultimatum (Latin for 'the last one'; /ˌʌltɪˈmeɪtəm/; pl.: ultimata or ultimatums) is a demand whose fulfillment is requested in a specified period of time and which is backed up by a threat to be followed through in case of noncompliance (open loop). An ultimatum is generally the final demand in a series of requests. As such, the time allotted is usually short, and the request is understood not to be open to further negotiation. The threat which backs up the ultimatum can vary depending on the demand in question and on the other circumstances.

The word is used in diplomacy to signify the final terms submitted by one of the parties in negotiation for settlement of any subject of disagreement. It is accompanied by an intimation as to how refusal will be regarded. English diplomacy has devised the adroit reservation that refusal will be regarded as an "unfriendly act", a phrase which serves as a warning that the consequences of the rupture of negotiations will be considered from the point of view of forcing a settlement. This opens up a variety of possibilities, such as good offices, mediation, the appointment of a commission of inquiry, arbitration, reprisals, pacific blockade and war.

Marko Mrnjavčević (Serbian Cyrillic: Марко Мрњавчевић, pronounced [mâːrko mr̩̂ɲaːʋt͡ʃeʋit͡ɕ] ; c. 1335 – 17 May 1395) was the de jure Serbian king from 1371 to 1395, while he was the de facto ruler of territory in western Macedonia centered on the town of Prilep. He is known as Prince Marko (Macedonian: Kрaле Марко; Serbian Cyrillic: Краљевић Марко, Kraljević Marko, IPA: [krǎːʎeʋit͡ɕ mâːrko]) and King Marko (Macedonian: Kрaл Марко; Serbian Cyrillic: Краљ Марко; Bulgarian: Крали Марко) in South Slavic oral tradition, in which he has become a major character during the period of Ottoman rule over the Balkans. Marko's father, King Vukašin, was co-ruler with Serbian Tsar Stefan Uroš V, whose reign was characterised by weakening central authority and the gradual disintegration of the Serbian Empire. Vukašin's holdings included lands in north-western Macedonia and Kosovo. In 1370 or 1371, he crowned Marko "young king"; this title included the possibility that Marko would succeed the childless Uroš on the Serbian throne.

On 26 September 1371, Vukašin was killed and his forces defeated in the Battle of Maritsa. About two months later, Tsar Uroš died. This formally made Marko the king of the Serbian land; however, Serbian noblemen, who had become effectively independent from the central authority, did not even consider to recognise him as their supreme ruler. Sometime after 1371, he became an Ottoman vassal; by 1377, significant portions of the territory he inherited from Vukašin were seized by other noblemen. King Marko, in reality, came to be a regional lord who ruled over a relatively small territory in western Macedonia. He funded the construction of the Monastery of Saint Demetrius near Skopje (better known as Marko's Monastery), which was completed in 1376. Later, Marko became an Ottoman vassal and died on 17 May 1395, fighting against the Wallachians in the Battle of Rovine.

Miloš Obrenović I (Serbian: Милош Обреновић I, romanized: Miloš Obrenović I; pronounced [mîloʃ obrěːnoʋit͡ɕ]; 18 March 1780 – 26 September 1860), born Miloš Teodorović (Serbian: Милош Теодоровић; pronounced [mîloʃ teodǒːroʋit͡ɕ]), also known as Miloš the Great (Serbian: Милош Велики, romanized: Miloš Veliki) was the Prince of Serbia twice, from 1815 to 1839, and from 1858 to 1860. He was an eminent figure of the First Serbian uprising, the leader of the Second Serbian uprising, and the founder of the house of Obrenović. Under his rule, Serbia became an autonomous principality within the Ottoman Empire. Prince Miloš was an autocrat, consistently refusing to decentralize power, which gave rise to a strong internal opposition. Despite his humble background, he eventually became the most affluent man in Serbia and one of the wealthiest in the Balkans, possessing estates in Vienna, Serbia and Wallachia. During his rule, Miloš bought a certain number of estates and ships from the Ottomans and was also a prominent trader.

Bulgarians (Romanian: bulgari) are a recognized minority in Romania (Bulgarian: Румъния, Rumaniya), numbering 7,336 according to the 2011 Romanian census, down from 8,025 in 2002. Despite their low census number today, Bulgarians from different confessional and regional backgrounds have had ethnic communities in various regions of Romania, and during the Middle Ages Bulgarian culture has exerted considerable influence on its northern neighbour. According to one Bulgarian estimate, Romanian citizens of Bulgarian origin number around 250,000. According to the Romanian census of 2021, among the 5,975 ethnic Bulgarians, 3,583 were Roman Catholics, 1,977 were Romanian Orthodox and 21 were Serbian Orthodox.

Historically, Bulgarian communities in modern Romania have existed in Wallachia (Bulgarian: Влашко, transliterated: Vlashko), Northern Dobruja (Bulgarian: Северна Добруджа, translit. Severna Dobrudzha) and Transylvania (Bulgarian: Седмиградско, translit. Sedmigradsko). Currently, however, the Bulgarian community in present-day Romania that has retained most efficiently its numbers, social integrity and strong ethnic identity is that of the Banat Bulgarians, a Roman Catholic minority in the Banat who account for the bulk of the Bulgarian-identifying population of Romania. In Wallachia, there are only few Bulgarians who have preserved their national identity, though the numbers of those who speak Bulgarian and affirm to have Bulgarian ancestors is still high.

A total of 41 counties (Romanian: județe), along with the municipality of Bucharest, constitute the official administrative divisions of Romania. They represent the country's NUTS-3 (Nomenclature of Territorial Units for Statistics – Level 3) statistical subdivisions within the European Union and each of them serves as the local level of government within its borders. Most counties are named after a major river, while some are named after notable cities within them, such as the county seat.

The earliest organization into județe of the Principalities of Wallachia and Moldavia (where they were termed ținuturi) dates back to at least the late 14th century. For most of the time since modern Romania was formed in 1859, the administrative division system has been similar to that of the French departments. The system has since changed several times and the number of counties has varied over time, from the 71 județe that existed before World War II to only 39 after 1968. The current format has largely been in place since 1968 as only small changes have been made since then, the last of which was in 1997.
