The Roman Empire conquered the territory between the Alps and the area west of the Danube River from 16 to 15 BCE, the Danube River being the new frontier of the empire. In 14 BCE, Pannonia, the western part of the Carpathian Basin, which includes today's west of Hungary, was recognised by emperor Augustus in the ''Res Gestae Divi Augusti'' as part of the Roman Empire. The area south-east of Pannonia and south of Dacia was organised as the Roman province Moesia in 6 BCE. An area east of the river Tisza became the Roman province of Dacia in 106 CE, which included today's east Hungary. It remained under Roman rule until 271 CE.
