[7] The Golden Horde's domination decreased in the region at the end of the 13th century, and at that time the Kingdom of Hungary also underwent a strong political crisis.
[5][9] Jean W. Sedlar wrote that "more credible" is the report that some Romanian lords in the Olt and Argeș valleys chose as leader one of their number, a certain Basarab.
[1] Basarab I received international support and the recognition of the autonomy of Wallachia due to his great military victory over King Charles I of Hungary (1301–1342) at Posada on November 12, 1330.
[13] Among the oldest attestations of the countries of the Vlachs (early Romanians) on the left side of the Danube, there is a quotation of a passage from an Armenian book of geography.
[19] The different Cuman groups were under independent rulers or khans who meddled in the political life of the surrounding areas, such as the Rus’ principalities and the Byzantine Empire.
[24] In 1211, King Andrew II of Hungary (1205–1235) settled the Teutonic Knights in the region of Brașov in order to put an end to the frequent incursions of the Cumans into Transylvania.
[28] That the Teutonic Knights won several victories "beyond the snowy mountains" (ultra montes nivium), that is to the south and to the east of the Carpathians, is also confirmed by papal letters.
[31][32] As early as 1227, one of the Cuman chieftains, Boricius subjected himself and his people to the future King Béla IV of Hungary, converted to Christianity and agreed to pay an annual tax and the tithe.
[36] In parallel with the emergence of the Second Bulgarian Empire, the Kingdom of Hungary also persuaded an active expansionist policy in the Balkan Peninsula from the end of the 12th century.
[40] In 1236 a large Mongol army was collected under the supreme leadership of Batu Khan and set forth to the west, in one of the greatest invasions in world's history.
[46] Although theoretically part of the Golden Horde, the steppe corridor between the Dnieper River and the lower Danube was only a "region of hegemony", not of direct control.
[55][56] Radu Negru and his followers crossed the Carpathians to Muntenia and founded Wallachia with its capitals in Câmpulung and Curtea de Argeș.
[57] But the word's exact meaning is debated, since there had been Romanians living in Wallachia before Radu Negru's arrival; thus the term likely refers simply to the unification of the lands under one ruler.
[57] Moreover, this account of Radu Negru's ‘dismounting’ may merely be a legend subsequently invented to parallel the circumstances by which Moldavia, the other Romanian principality was founded according to the earliest chronicles.
[53][61] Due to lack of any actual contemporary evidence, the Roman historian Nicolae Iorga doubted the existence of such a voivode, considering that 'Negru Vodă' is simply a nickname that could have been given to Basarab I, the real founder of Wallachia.
[60] Other view is represented by Neagu Djuvara who identifies Negru Vodă with Thocomerius, Basarab's father, explaining his nickname by his alleged Cuman descent: he appeared to have a dark skin color for the Romanians.
[63] The legendary traditions may also be in connection with the establishment of a trans-Carpathian frontier mark by the Hungarian monarchy, with its capital at Câmpulung, probably in the last decade of the 13th century.
[8] A tomb stone belonging to one of the leaders of this formation, Count Lawrence of Câmpulung (comes Laurentius de Longo Campo), dating from the year 1300, may provide a solid chronological reference point.
Others went downward establishing towns and villages, and they reached all the places as far as the banks of the Danube and all along the Olt.In 6798 AM, there was a voievode called Voievod Radu the Black, who had his seat at Făgăraș from the fathers and forefathers of the Romanians who had come from Rome, in the days of Emperor Trajan decided to move his seat on the other side [of the Carpathians] – Chronicle of Radu Popescu (Cronica Balenilor)[67]Basarab was the son of Thocomerius whose status cannot be specified.
[70] The voivode asked for a truce, offering to refund 7,000 silver marks for the costs of the army, and showed himself ready to continue paying tribute to the king and send his son as a hostage to the royal court.
[70] The Battle of Posada was a turning point in Hungarian-Wallachian relations: though in the course of the 14th century, the kings of Hungary still tried to regulate the voivodes of Wallachia more than one time, but they could only succeed temporarily.
[11] Only a few months after his great victory, in February 1331, Basarab contributed to the establishment of his son-in-law, Ivan Alexander (1331–1371) on the throne of the tzars of Bulgaria in Tarnovo.
[71] As a way of solemnizing his secession from the Kingdom of Hungary, Basarab's son, Nicolae Alexandru also sought Byzantine approval for the creation of an Orthodox see for his territories.
[72] In 1359 Byzantium acceded to his request that the displaced metropolitan of Vicina, Hyakinthos – whom Nicolae Alexander had been hosting at his court for some time – should become the "legitimate pastor of all Oungrovlachia for the blessing and spiritual direction of himself, his children and all his lordship".
[80] However, the origin of the Romanian boyar class is problematic: it may have evolved naturally from the heads of the Vlach villages and communities, but it is also possible that the princes created it by granting privileges to certain favored persons.
[81] Multiple vassalage became an important aspect of Romanian diplomacy after the Christian Balkan states (Bulgaria, Serbia) one by one fell to the Ottoman Empire in the course the second half of the 14th century.
