The Early Middle Ages in Romania started with the withdrawal of the Roman troops and administration from Dacia province in the 270s. In the next millennium a series of peoples, most of whom only controlled two or three of the nearly ten historical regions that now form Romania, arrived. During this period, society and culture underwent fundamental changes. Town life came to an end in Dacia with the Roman withdrawal, and in Scythia Minorthe other Roman province in the territory of present-day Romania400 years later. Fine vessels made on fast potter's wheels disappeared and hand-made pottery became dominant from the 450s. Burial rites changed more than once from cremation to inhumation and vice versa until inhumation became dominant by the end of the 10th century. The East Germanic Goths and Gepids, who lived in sedentary communities, were the first new arrivals. The Goths dominated Moldavia and Wallachia from the 290s, and parts of Transylvania from the 330s. Their power collapsed under attacks by the nomadic Huns in 376. The Huns controlled Eastern and Central Europe from around 400, but their empire disintegrated in 454. Thereafter the regions west of the Carpathian MountainsBanat, Crişana, and Transylvaniaand Oltenia were dominated by the Gepids. Within a century, the lands east of the mountains became important centers of the Antes and Sclavenes. Hydronyms and place names of Slavic origin also prove the one-time presence of Early Slavs in the regions west of the Carpathians. The nomadic Avars subjugated the Gepids in 568 and dominated the Carpathian Basin up until around 800. The Bulgars also established a powerful empire in the 670s which included Dobruja and other territories along the Lower Danube. Bulgaria officially adopted the Eastern Orthodox variant of Christianity in 864. An armed conflict between Bulgaria and the nomadic Hungarians forced the latter to depart from the Pontic steppes and began the conquest of the Carpathian Basin around 895. Their invasion gave rise to the earliest reference, recorded some centuries later in the Gesta Hungarorum, to a polity ruled by a Romanian duke named Gelou. The same source also makes mention of the presence of the Székelys in Crişana around 895. The first contemporaneous references to Romanianswho used to be known as Vlachsin the regions now forming Romania were recorded in the 12th and 13th centuries. References to Vlachs inhabiting the lands to the south of the Lower Danube abound in the same
