Ammianus Marcellinus, occasionally anglicised as Ammian, was a Roman soldier and historian who wrote the penultimate major historical account surviving from antiquity. Written in Latin and known as the Res gestae, his work chronicled the history of Rome from the accession of the Emperor Nerva in 96 to the death of Valens at the Battle of Adrianople in 378. Only the sections covering the period 353 to 378 survive.
The Bastarnae, sometimes called the Peuci or Peucini, were an ancient people who between 200 BC and 300 AD inhabited areas north of the Roman frontier on the Lower Danube. The Bastarnae lived in the region between the Carpathian Mountains and the river Dnieper, to the north and east of ancient Dacia. The Peucini were a subtribe who occupied the region north of the Danube Delta. Their name was sometimes used for the Bastarnae as a whole.
Constantius II was Roman emperor from 337 to 361. His reign saw constant warfare on the borders against the Sasanian Empire and Germanic peoples, while internally the Roman Empire went through repeated civil wars, court intrigues, and usurpations. His religious policies inflamed domestic conflicts that would continue after his death.
Flavius Julius Constans, also called Constans I, was Roman emperor from 337 to 350. He held the imperial rank of caesar from 333, and was the youngest son of Constantine the Great.
Julian was the Caesar of the West from 355 to 360 and Roman emperor from 361 to 363, as well as a notable philosopher and author in Greek. His rejection of Christianity, and his promotion of Neoplatonic Hellenism in its place, caused him to be remembered as Julian the Apostate in Christian tradition. He is sometimes referred to as Julian the Philosopher.
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.
The Battle of Adrianople, sometimes known as the Battle of Hadrianopolis, was fought between an Eastern Roman army led by the Eastern Roman Emperor Valens and Gothic rebels led by Fritigern. The battle took place in the vicinity of Adrianople, in the Roman province of Thracia. It ended with an overwhelming victory for the Goths and the death of Emperor Valens.
Valentinian I, sometimes called Valentinian the Great, was Roman emperor from 364 to 375. He ruled the Western half of the empire, while his brother Valens ruled the East. During his reign, he fought successfully against the Alamanni, Quadi, and Sarmatians, strengthening the border fortifications and conducting campaigns across the Rhine and Danube. His general Theodosius defeated a revolt in Africa and the Great Conspiracy, a coordinated assault on Roman Britain by Picts, Scoti, and Saxons. Valentinian founded the Valentinianic dynasty, with his sons Gratian and Valentinian II succeeding him in the western half of the empire.
The Iazyges were an ancient Sarmatian tribe that traveled westward in c. 200 BC from Central Asia to the steppes of modern Ukraine. In c. 44 BC, they moved into modern-day Hungary and Serbia near the Dacian steppe between the Danube and Tisza rivers, where they adopted a semi-sedentary lifestyle.
The Roxolani or Rhoxolāni were a Sarmatian people documented between the 2nd century BC and the 4th century AD, first east of the Borysthenes (Dnieper) on the coast of Lake Maeotis, and later near the borders of Roman Dacia and Moesia. They are believed to be an offshoot of the Alans.
Banat is a geographical and historical region located in the Pannonian Basin that straddles Central and Eastern Europe. It is divided among three countries: the eastern part lies in western Romania ; the western part of Banat is in northeastern Serbia ; and a small northern part lies within southeastern Hungary.
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.
The Lentienses were a 4th-century Germanic tribe associated with the Alemanni, in the region between the river Danube in the North, the river Iller in the East, and Lake Constance in the South, in what is now southern Germany. They were reported to be one of the most rebellious tribes at the time. There are only two mentions of the Lentienses, both by the Roman historian Ammianus Marcellinus (330–395).
Paulus Catena was a senior Roman public official who served as an investigator and notary for Constantius II during the mid-fourth century. He is principally known through the writings of Ammianus Marcellinus, though he is also present in the works of Libanius and Julian the Apostate. Marcellinus describes him as infamously cruel, and a skilled fabricator of false accusations.
Ursicinus was a Roman senior military officer, holding the rank of Magister Equitum per Orientem and even Magister Peditum Praesentalis in the later Roman Empire c. 349–359. He was a citizen of Antioch and was well connected in the Eastern part of the Roman Empire.
The Goths, Gepids, Vandals, and Burgundians were East Germanic groups who appear in Roman records in late antiquity. At times these groups warred against or allied with the Roman Empire, the Huns, and various Germanic tribes.
The Victohali were a people of Late Antiquity who lived north of the Lower Danube. In Greek their name is Biktoa or Biktoloi. They were possibly a Germanic people, and it has been suggested that they were one of the tribes of the Vandals.
The Argaragantes were a Sarmatian tribe that lived by the Tisza river, in Banat, in the 4th century.
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.
Montes Serrorum is a mountain somewhere in the Carpathians mentioned by Roman soldier Ammianus Marcellinus (325–391) regarding events in the Gothic War (367–369).
