Moesia (ˈmiːʃə,-siə,-ʒə; Latin: Moesia; Moisía) was an ancient region and later Roman province situated in the Balkans south of the Danube River, which included most of the territory of modern eastern Serbia, Kosovo, north-eastern Albania, northern parts of North Macedonia (Moesia Superior), Northern Bulgaria, Romanian Dobruja and small parts of Southern Ukraine (Moesia Inferior). In ancient geographical sources, Moesia was bounded to the south by the Haemus (Balkan Mountains) and Scardus (Šar) mountains, to the west by the Drinus (Drina) river, on the north by the Donaris (Danube) and on the east by the Euxine (Black Sea). The region was inhabited chiefly by Thracians, Illyrian and Thraco-Illyrian peoples. The name of the region comes from Moesi, a Thracian tribe who lived there before the Roman conquest. Parts of Moesia belonged to the polity of Burebista, a Getae king who established his rule over a large part of the northern Balkans between 82 BC and 44 BC. He led plunder and conquest raids across Central and Southeastern Europe, subjugating most of the neighbouring tribes. After his assassination in an inside plot, the empire was divided into several smaller states. In 75 BC, C. Scribonius Curio, proconsul of Macedonia, took an army as far as the Danube and gained a victory over the inhabitants, who were finally subdued by M. Licinius Crassus, grandson of the triumvir and later also proconsul of Macedonia during the reign of Augustus c. 29 BC. The region, however, was not organized as a province until the last years of Augustus' reign; in 6 AD, mention is made of its governor, Caecina Severus. As a province, Moesia was under an imperial consular legate (who probably also had control of Achaea and Macedonia). In AD 86, the Dacian king Duras ordered his troops to attack Roman Moesia. After this attack, the Roman emperor Domitian personally arrived in Moesia and reorganized it in 87 AD into two provinces, divided by the river Cebrus (Ciabrus): to the west Moesia Superior or Upper Moesia (meaning upriver) and to the east Moesia Inferior or Lower Moesia or Ripa Thracia (from the Danube river's mouth and then upstream).
