Wallachia or Walachia is a historical and geographical region of Romania. It is situated south of the Southern Carpathians. Wallachia is traditionally divided into two sections and Oltenia. Wallachia as a whole is sometimes referred to as Muntenia through identification with the larger of the two traditional sections. Wallachia was founded as a principality in the early 14th century by Basarab I, after a rebellion against Charles I of Hungary, although the first mention of the territory of Wallachia west of the river Olt dates to a charter given to the voivode Seneslau in 1246 by Béla IV of Hungary. In 1417, Wallachia accepted the suzerainty of the Ottoman Empire. In 1859, Wallachia united with Moldavia to form the United Principalities, which adopted the name Romania in 1866 and became the Kingdom of Romania in 1881. Following the dissolution of the Austro-Hungarian Empire and the resolution of the elected representatives of Romanians in 1918, Transylvania as well as parts of Banat, Crișana, Maramureș were allocated to the Kingdom of Romania, thereby forming the modern Romanian state.

The name Wallachia is an exonym not used by Romanians themselves who used the denomination "Țara Românească/Rumânească" – Romanian Land. The term "Wallachia" is derived from the term walhaz used by Germanic peoples to describe Celts, romanized Celts and all Romance-speaking people. In Northwestern Europe this gave rise to Wales and Wallonia, among others, while in Southeast Europe it was used to designate Romance-speakers, subsequently shepherds generally. In the Early Middle Ages, in Slavonic texts, the name Zemli Ungro-Vlahiskoi was used as a designation for its location; the term, translated in Romanian as "Ungrovalahia", remained in use up to the modern era in a religious context, referring to the Romanian Orthodox Metropolitan seat of Hungaro-Wallachia, in contrast to Thessalian or Great Vlachia in Greece or Small Wallachia in Serbia. The Romanian-language designations of the state were Muntenia, Țara Românească, RomâniaFor long periods after the 14th century, Wallachia was referred to as Vlaško by Bulgarian sources, Vlaška by Serbian sources, Voloschyna by Ukrainian sources and Walachei or Walachey by German-speaking sources.

The traditional Hungarian name for Wallachia is Havasalföld "Snowy Lowlands", the older form of, Havaselve, meaning "Land beyond the snowy mountains". In Ottoman Turkish, the term Eflâk Prensliği, or simply"Eflâk افلاق, appears. Arabic chronicles from the 13th century had used the name of Wallachia instead of Kingdom of Bulgaria, they gave the coordinates of Wallachia and specified that Wallachia was named al-Awalak and the dwellers ulaqut or ulagh. The area of Oltenia in Wallachia was known in Turkish as Kara-Eflak and Kuçuk-Eflak, while the former has been used for Ottoman Moldova. In the Second Dacian War western Oltenia became part of the Roman province of Dacia, with parts of Wallachia included in the Moesia Inferior province; the Roman limes was built along the Olt River in 119 before being moved to the east in the second century, during which time it stretched from the Danube up to Rucăr in the Carpathians. The Roman line fell back to the Olt in 245 and, in 271, the Romans pulled out of the region.

The area was subject to Romanization during the Migration Period, when most of present-day Romania was invaded by Goths and Sarmatians known as the Chernyakhov culture, followed by waves of other nomads. In 328, the Romans built a bridge between Sucidava and Oescus which indicates that there was a significant trade with the peoples north of the Danube. A short period of Roman rule in the area is attested under Emperor Constantine the Great, after he attacked the Goths in 332; the period of Goth rule ended when the Huns arrived in the Pannonian Basin and, under Attila and destroyed some 170 settlements on both sides of the Danube. Byzantine influence is evident during the 5th to 6th century, such as the site at Ipotești-Cândești, but from the second half of the 6th century and in the seventh century, Slavs crossed the territory of Wallachia and settled in it, on their way to Byzantium, occupying the southern bank of the Danube. In 593, the Byzantine commander-in-chief Priscus defeated Slavs and Gepids on future Wallachian territory, and, in 602, Slavs suffered a crucial defeat in the area.

Wallachia was under the control of the First Bulgarian Empire from its establishment in 681, until the Hungarians' conquest of Transylvania at the end of the 10th century. W
