Aurelian was a Roman emperor who reigned from 270 to 275 during the Crisis of the Third Century. As emperor, he won an unprecedented series of military victories which reunited the Roman Empire after it had nearly disintegrated under the pressure of barbarian invasions and internal revolts. Born in modest circumstances, most likely in Moesia Superior, he entered the Roman army in 235 and climbed up the ranks. He went on to lead the cavalry of the emperor Gallienus, until Gallienus' assassination in 268. Following that, Claudius Gothicus became emperor until his own death in 270. Claudius' brother Quintillus then ruled for three months, before Aurelian took the empire for himself.
Marcus Aurelius Claudius "Gothicus", also known as Claudius II, was Roman emperor from 268 to 270. During his reign he fought successfully against the Alemanni and decisively defeated the Goths at the Battle of Naissus. He died after succumbing to a "pestilence", possibly the Plague of Cyprian that had ravaged the provinces of the Empire.
Dacia was the land inhabited by the Dacians, its core in Transylvania, stretching to the Danube in the south, the Black Sea in the east, and the Tisza in the west. The Carpathian Mountains were located in the middle of Dacia. It thus roughly corresponds to present-day Romania, as well as parts of Moldova, Bulgaria, Serbia, Hungary, Slovakia, and Ukraine.
Justin II was Eastern Roman emperor from 565 until 578. He was the nephew of Justinian I and the husband of empress Sophia, the niece of the empress Theodora, and a member of the Justinian dynasty.
Marcus Aurelius Probus was Roman emperor from 276 to 282. Probus was an active and successful general as well as a conscientious administrator, and in his reign of six years he secured prosperity for the inner provinces while withstanding repeated invasions of barbarian tribes on almost every sector of the frontier.
Gratian was emperor of the Western Roman Empire from 367 to 383. The eldest son of Valentinian I, Gratian was raised to the rank of Augustus as a child and inherited the West after his father's death in 375. He nominally shared the government with his infant half-brother Valentinian II, who was also acclaimed emperor in Pannonia on Valentinian's death. The East was ruled by his uncle Valens, who was later succeeded by Theodosius I.
Legio XXII Primigenia was a legion of the Imperial Roman army dedicated to the goddess Fortuna Primigenia. Founded in AD 39 by the emperor Caligula for use in his campaigns in Germania, the XXII Primigenia spent much of their time in Mogontiacum up to the end of the 3rd century. The legion's symbols were a Capricorn and the demigod Hercules.
The Carpi or Carpiani were a tribe that resided in the eastern parts of modern Romania in the historical region of Moldavia from no later than c. AD 140 and until at least AD 318.
This is a chronology of warfare between the Romans and various Germanic peoples. The nature of these wars varied through time between Roman conquest, Germanic uprisings, later Germanic invasions of the Western Roman Empire that started in the late second century BC, and more. The series of conflicts was one factor which led to the ultimate downfall of the Western Roman Empire in particular and ancient Rome in general in 476.
The so-called Free Dacians is the name given by some modern historians to those Dacians who remained outside, or emigrated from, the Roman Empire after the emperor Trajan's Dacian Wars. Dio Cassius named them Dakoi prosoroi meaning "neighbouring Dacians".
The Marcomannic Wars were a series of wars lasting from about AD 166 until 180. These wars pitted the Roman Empire against principally the Germanic Marcomanni and Quadi and the Sarmatian Iazyges; there were related conflicts with several other Germanic, Sarmatian, and Gothic peoples along both sides of the whole length of the Roman Empire's northeastern European border, the river Danube.
As with most other military forces the Roman military adopted an extensive list of decorations for military gallantry and likewise a range of punishments for military transgressions.
The Parthian war of Caracalla was an unsuccessful campaign by the Roman Empire under Caracalla against the Parthian Empire in 216–17 AD. It was the climax of a four-year period, starting in 213, when Caracalla pursued a lengthy campaign in central and eastern Europe and the Near East. After intervening to overthrow rulers in client kingdoms adjoining Parthia, he invaded in 216 using an abortive wedding proposal to the Parthian king Artabanus's daughter as a casus belli. His forces carried out a campaign of massacres in the northern regions of the Parthian Empire before withdrawing to Asia Minor, where he was assassinated in April 217. The war was ended the following year after Parthian victory at the Battle of Nisibis, with the Romans paying a huge sum of war reparations to the Parthians.
Cannabaudes or Cannabas was a third-century leader of the Gothic tribe of the Tervings, who died in a battle against the Roman emperor Aurelian.
The German and Sarmatian campaigns of Constantine were fought by the Roman Emperor Constantine I against the neighbouring Germanic peoples, including the Franks, Alemanni and Goths, as well as the Sarmatian Iazyges, along the whole Roman northern defensive system to protect the empire's borders, between 306 and 336.
The barbarian invasions of the third century (212–305) constituted an uninterrupted period of raids within the borders of the Roman Empire, conducted for purposes of plunder and booty by armed peoples belonging to populations gravitating along the northern frontiers: Picts, Caledonians, and Saxons in Britain; the Germanic tribes of Frisii, Saxons, Franks, Alemanni, Burgundians, Marcomanni, Quadi, Lugii, Vandals, Juthungi, Gepids and Goths, the Dacian tribes of the Carpi and the Sarmatian tribes of Iazyges, Roxolani and Alans, as well as Bastarnae, Scythians, Borani and Heruli along the Rhine-Danube rivers and the Black Sea.
