The Alemanni or Alamanni were a confederation of Germanic tribes on the Upper Rhine River during the first millennium. First mentioned by Cassius Dio in the context of the campaign of Roman emperor Caracalla of 213, the Alemanni captured the Agri Decumates in 260, and later expanded into present-day Alsace and northern Switzerland, leading to the establishment of the Old High German language in those regions, which by the eighth century were collectively referred to as Alamannia.
Honorius was Roman emperor from 393 to 423. He was the younger son of emperor Theodosius I and his first wife Aelia Flaccilla. After the death of Theodosius in 395, Honorius, under the regency of Stilicho, ruled the western half of the empire while his brother Arcadius ruled the eastern half. His reign over the Western Roman Empire was notably precarious and chaotic. In 410, Rome was sacked for the first time in almost 800 years.
The 360s decade ran from January 1, 360, to December 31, 369.
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.
Aetius was a Roman general and statesman of the closing period of the Western Roman Empire. He was a military commander and the most influential man in the Empire for two decades (433–454). He managed policy in regard to the attacks of barbarian federates settled throughout the West. Notably, he mustered a large Roman and allied (foederati) army in the Battle of the Catalaunian Plains, ending a devastating invasion of Gaul by Attila in 451, though the Hun and his subjugated allies still managed to invade Italy the following year, an incursion best remembered for the ruthless Sack of Aquileia and the intercession of Pope Leo I.
Stilicho was a military commander in the Roman army who, for a time, became the most powerful man in the Western Roman Empire. He was of Vandal origins and married to Serena, the niece of emperor Theodosius I. He became guardian for the underage Honorius. After nine years of struggle against barbarian and Roman enemies, political and military disasters finally allowed his enemies in the court of Honorius to remove him from power. His fall culminated in his arrest and execution in 408.
Count Theodosius or Theodosius the Elder, was a senior military officer serving Valentinian I and the Western Roman Empire during Late Antiquity. Under his command the Roman army defeated numerous threats, incursions, and usurpations. Theodosius was patriarch of the imperial Theodosian dynasty and father of the emperor Theodosius the Great.
The fall of the Western Roman Empire, also called the fall of the Roman Empire or the fall of Rome, was the loss of central political control in the Western Roman Empire, a process in which the Empire failed to enforce its rule, and its vast territory was divided between several successor polities. The Roman Empire lost the strengths that had allowed it to exercise effective control over its Western provinces; modern historians posit factors including the effectiveness and numbers of the army, the health and numbers of the Roman population, the strength of the economy, the competence of the emperors, the internal struggles for power, the religious changes of the period, and the efficiency of the civil administration. Increasing pressure from invading barbarians outside Roman culture also contributed greatly to the collapse. Climatic changes and both endemic and epidemic disease drove many of these immediate factors. The reasons for the collapse are major subjects of the historiography of the ancient world and they inform much modern discourse on state failure.
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 Great Conspiracy was a year-long state of war and disorder that occurred near the end of Roman Britain. The historian Ammianus Marcellinus described it as a barbarica conspiratio, which took advantage of a depleted military force in the province; many soldiers had marched with Magnentius in his unsuccessful bid to become emperor. Few returned, and supply, pay, and discipline in the following years may have been deficient.
The Battle of Verona was fought in June 402 by Alaric's Visigoths and a Western Roman force led by Stilicho. Alaric was defeated and forced to withdraw from Italy.
The Battle of the Save was fought in 388 between the forces of Roman usurper Magnus Maximus and the Eastern Roman Empire. Emperor Theodosius I defeated Magnus Maximus's army in battle. Later Maximus was captured and executed at Aquileia.
In the Battle of Châlons, fought in 274 on the site of modern Châlons-en-Champagne, France, Roman Emperor Aurelian defeated Emperor Tetricus I of the Gallic Empire, whose territories were rejoined with the Roman Empire after fourteen years of separation.
The Battle of Pollentia was fought on 6 April 402 (Easter) between the Romans under Stilicho and the Visigoths under Alaric I, during the first Gothic invasion of Italy (401–403). The Romans were victorious, and forced Alaric to retreat, though he rallied to fight again in the next year in the Battle of Verona, where he was again defeated. After this, Alaric retreated from Italy, leaving the province in peace until his second invasion in 409, after Stilicho's death.
The Battle of Lingones was fought in 298 between the Western Roman Empire and the Alamanni. The Roman force was led by Constantius Chlorus, and was victorious.
The siege of Autun was a conflict fought between the Roman Empire and the invading barbarian Alemanni tribe, who were ravaging Gaul, in 356 AD. The Romans successfully defended the city, and the barbarians retreated on the approach of reinforcements.
Chnodomar was the king of an Alamannic canton in what is now south-west Germany, near the Rhine from sometime before 352 till 357. He seems to have had a recognized position among the other Alamanni.
Flavius Arintheus was a Roman army officer who started his career in the middle ranks and rose to senior political and military positions. He served the emperors Constantius II, Julian, Jovian and Valens. In 372 he was appointed consul, alongside Domitius Modestus.
Dagalaifus was a Roman army officer of Germanic descent. A pagan, he served as consul in 366. In the year 361, he was appointed by Emperor Julian as comes domesticorum. He accompanied Julian on his march through Illyricum to quell what remained of the government of Constantius II that year. He led a party into Sirmium that arrested the commander of the resisting army, Lucillianus. In the spring of 363, Dagalaifus was part of Julian's ultimately-disastrous invasion of Persia. On June 26, while still campaigning, Julian was killed in a skirmish. Dagalaifus, who had been with the rear guard, played an important role in the election of the next emperor. The council of military officers finally agreed on the new comes domesticorum, Jovian, to succeed Julian. Jovian was a Christian whose father Varronianus had himself once served as comes domesticorum.
Flavius Jovinus was a Roman general and consul of the Western Roman Empire. He was of Gallic or Germanic origin and was both born and buried in Durocortorum, modern day Reims.
