Moesia (; Latin: Moesia; ) was an ancient region and later Roman province situated in the Balkans south of the Danube River. Moesian Province was first administered by governor of Noricum as 'Civitates of Moesia and Triballia'. It 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).
Geography
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).
History
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). Each was governed by an imperial consular legate and a procurator.
The chief towns of Upper Moesia in the Principate were: Singidunum (Belgrade), Viminacium (sometimes called municipium Aelium; modern Kostolac), Remesiana (Bela Palanka), Bononia (Vidin), Ratiaria (Archar) and Skupi (modern Skopje); of Lower Moesia: Oescus (colonia Ulpia, Gigen), Novae (near Svishtov, the chief seat of Theodoric the Great), Nicopolis ad Istrum (Nikup; really near the river Yantra), Marcianopolis (Devnya), Tyras (Bilhorod-Dnistrovskyi), Olvia, Odessus (Varna) and Tomis (Constanţa; to which the poet Ovid was banished). The last two were Greek towns which formed a pentapolis with Istros, Mesembria (Nessebar) and Apollonia (Sozopol).
From Moesia, Domitian began planning future campaigns into Dacia and by 87 he started a strong offensive against Dacia, ordering General Cornelius Fuscus to attack. Therefore, in the summer of 87, Fuscus led five or six legions across the Danube. The campaign against the Dacians ended without a decisive outcome, and Decebalus, the Dacian King, had brazenly flouted the terms of the peace (89 AD) which had been agreed on at the war's end.
Emperor Trajan later arrived in Moesia, and he launched his first military campaign into the Dacian Kingdom c. March–May 101, crossing to the northern bank of the Danube River and defeating the Dacian army near Tapae, a mountain pass in the Carpathians (see Second Battle of Tapae). Trajan's troops were mauled in the encounter, however, and he put off further campaigning for the year to heal troops, reinforce, and regroup. During the following winter, King Decebalus launched a counter-attack across the Danube further downstream, but this was repulsed. Trajan's army advanced further into Dacian territory and forced King Decebalus to submit to him a year later.
Trajan returned to Rome in triumph and was granted the title Dacicus. The victory was celebrated by the Tropaeum Traiani. However, Decebalus in 105 undertook an invasion against Roman territory by attempting to stir up some of the tribes north of the river against the empire. Trajan took to the field again and after building with the design of Apollodorus of Damascus his massive bridge over the Danube, he conquered part of Dacia in 106 (see also Second Dacian War).
Sometime around 272, at the Moesian city of Naissus or Nissa (modern Niš in Serbia), future emperor Constantine I was born.
