Constantine II was Roman emperor from 337 to 340. Son of Constantine the Great and co-emperor alongside his brothers, his attempt to exert his perceived rights of primogeniture led to his death in a failed invasion of Italy in 340.
The Suebi or Suebians were a large group of Germanic peoples originally from the Elbe river region in what is now Germany and the Czech Republic. In the early Roman era they included many peoples with their own names such as the Marcomanni, Quadi, Hermunduri, Semnones, and Lombards. New groupings formed later, such as the Alamanni and Bavarians, and two kingdoms in the Migration Period were simply referred to as Suebian.
The 270s decade ran from January 1, 270, to December 31, 279.
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 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.
The Carpi or Carpiani were a Dacian 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 Valentinian dynasty was a ruling house of five generations of dynasts, including five Roman emperors during Late Antiquity, lasting nearly a hundred years from the mid fourth to the mid fifth century. They succeeded the Constantinian dynasty and reigned over the Roman Empire from 364 to 392 and from 425 to 455, with an interregnum (392–423), during which the Theodosian dynasty ruled and eventually succeeded them. The Theodosians, who intermarried into the Valentinian house, ruled concurrently in the east after 379.
The Marcomannic Wars were a series of wars lasting from about 166 until 180 AD. 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.
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.
