Romanian-speaking inhabitants. But this hypothesis lacks evidential basis (e.g. the absence of any post-275 Latin inscriptions in the region, other than on imported Roman coins/artefacts). What is certain is that by AD 300, the entire North Danubian region had fallen under the political domination of Germanic-speaking groups, a hegemony that continued until c. AD 500: the Goths held overall hegemony, and under them, lesser Germanic tribes such as the Taifali and Gepids. Some historians consider that the region became Germanic-speaking during this period. At least one part, Wallachia, may have become Slavic-speaking by AD 600, as it is routinely referred to "Sklavinía" (Greek for "Land of the Slavs") by contemporary Byzantine chroniclers. The survival of the Dacian language in this period is impossible to determine, due to a complete lack of documentation. However, it is generally believed that the language was extinct by AD 600.
