Bagaudae

Feudalism, also known as the feudal system, is a term used to describe the legal, economic, military, cultural and political customs that flourished in medieval Europe between the 9th and 15th centuries. Broadly defined, it was a way of structuring society around relationships that were derived from the holding of land in exchange for service or labour. Although it is derived from the Latin word feodum or feudum (fief), which was used during the Medieval period, the term feudalism and the system which it describes were not conceived of as a formal political system by the people who lived during the Middle Ages. The classic definition, by François Louis Ganshof (1944), describes a set of reciprocal legal and military obligations which existed among the warrior nobility and revolved around the three key concepts of lords, vassals, and fiefs.

The Western Roman Empire comprised the western provinces of the Roman Empire at any time during which they were administered by a separate independent Imperial court; in particular, this term is used in historiography to describe the period from 395 to 476, where there were separate coequal courts dividing the governance of the empire in the Western and the Eastern provinces, with a distinct imperial succession in the separate courts. The terms Western Roman Empire and Eastern Roman Empire were coined in modern times to describe political entities that were de facto independent; contemporary Romans did not consider the Empire to have been split into two empires but viewed it as a single polity governed by two imperial courts as an administrative expediency. The Western Roman Empire collapsed in 476, and the Western imperial court in Ravenna was formally dissolved by Justinian in 554. The Eastern imperial court survived until 1453.

Maximian, nicknamed Herculius, was Roman emperor from 286 to 305. He was Caesar from 285 to 286, then Augustus from 286 to 305. He shared the latter title with his co-emperor and superior, Diocletian, whose political brain complemented Maximian's military brawn. Maximian established his residence at Trier but spent most of his time on campaign. In late 285, he suppressed rebels in Gaul known as the Bagaudae. From 285 to 288, he fought against Germanic tribes along the Rhine frontier. Together with Diocletian, he launched a scorched earth campaign deep into Alamannic territory in 288, refortifying the frontier.

Marcus Aurelius Mausaeus Carausius was a military commander of the Roman Empire in the 3rd century. He was a Menapian from Belgic Gaul, who usurped power in 286, during the Carausian Revolt, declaring himself emperor in Britain and northern Gaul. He did this only 13 years after the Gallic Empire of the Batavian Postumus was ended in 273. He held power for seven years, fashioning the name "Emperor of the North" for himself, before being assassinated by his finance minister Allectus.

Diocletian, nicknamed "Jovius", was Roman emperor from 284 until his abdication in 305. He was born Diocles to a family of low status in the Roman province of Dalmatia. Diocles rose through the ranks of the military early in his career, eventually becoming a cavalry commander for the army of Emperor Carus. After the deaths of Carus and his son Numerian on a campaign in Persia, Diocles was proclaimed emperor by the troops, taking the name Diocletianus. The title was also claimed by Carus's surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus.

Gallia Belgica was a province of the Roman Empire located in the north-eastern part of Roman Gaul, in what is today primarily northern France, Belgium, and Luxembourg, along with parts of the Netherlands and Germany.

The Frumentarii were an ancient Roman military organization used as an intelligence agency. They began their history as a courier service and developed into an imperial spying agency. Their organization would also carry out assassinations. The frumentarii were headquartered in the Castra Peregrina and were run by the princeps peregrinorum. They were disbanded under the reign of Diocletian due to their poor reputation amongst the populace.

Lugdunum was an important Roman city in Gaul, established on the current site of Lyon. The Roman city was founded in 43 BC by Lucius Munatius Plancus, but continued an existing Gallic settlement with a likely population of several thousands. It served as the capital of the Roman province of Gallia Lugdunensis and was an important city in the western half of the Roman Empire for centuries. Two emperors, Claudius and Caracalla, were born in Lugdunum. In the period 69–192 AD, the city's population may have numbered 50,000 to 100,000, and possibly up to 200,000 inhabitants.

The Heruli were an early Germanic people. Possibly originating in Scandinavia, the Heruli are first mentioned by Roman authors as one of several "Scythian" groups raiding Roman provinces in the Balkans and the Aegean Sea, attacking by land, and notably also by sea. During this time they reportedly lived near the Sea of Azov.

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.

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.

Brittany is a peninsula, historical country and cultural area in the north-west of modern France, covering the western part of what was known as Armorica during the period of Roman occupation. It became an independent kingdom and then a duchy before being united with the Kingdom of France in 1532 as a province governed as a separate nation under the crown.

The Alans were an ancient and medieval Iranian nomadic pastoral people of the North Caucasus – generally regarded as part of the Sarmatians, and possibly related to the Massagetae. Modern historians have connected the Alans with the Central Asian Yancai of Chinese sources and with the Aorsi of Roman sources. Having migrated westwards and becoming dominant among the Sarmatians on the Pontic–Caspian steppe, the Alans are mentioned by Roman sources in the 1st century CE. At that time they had settled the region north of the Black Sea and frequently raided the Parthian Empire and the Caucasian provinces of the Roman Empire. From 215–250 CE the Goths broke their power on the Pontic Steppe.

Armorica or Aremorica is the name given in ancient times to the part of Gaul between the Seine and the Loire that includes the Brittany Peninsula, extending inland to an indeterminate point and down the Atlantic Coast.

Germanus of Auxerre was a western Roman clergyman who was bishop of Autissiodorum in Late Antique Gaul. He abandoned a career as a high-ranking government official to devote his formidable energy towards the promotion of the church and the protection of his "flock" in dangerous times, personally confronting, for instance, the barbarian king "Goar". In Britain he is best remembered for his journey to combat Pelagianism in or around 429 AD, and the records of this visit provide valuable information on the state of post-Roman British society. He also played an important part in the establishment and promotion of the Cult of Saint Alban. The saint was said to have revealed the story of his martyrdom to Germanus in a dream or holy vision, and Germanus ordered this to be written down for public display. Germanus is venerated as a saint in both the Roman Catholic and Orthodox churches, which commemorate him on 31 July.

Arcadius was Roman emperor from 383 to his death in 408. He was the eldest son of the Augustus Theodosius I and his first wife Aelia Flaccilla, and the brother of Honorius. Arcadius ruled the eastern half of the empire from 395, when their father died, while Honorius ruled the west. A weak ruler, his reign was dominated by a series of powerful ministers and by his wife, Aelia Eudoxia.

The Ebro is a river of the north and northeast of the Iberian Peninsula, in Spain. It rises in Cantabria and flows 930 kilometres (580 mi), almost entirely in an east-southeast direction. It flows into the Mediterranean Sea forming a delta in the Province of Tarragona, in southern Catalonia. In the Iberian peninsula, it ranks second in length after the Tagus and second in discharge volume, and drainage basin, after the Douro. It is the longest river entirely within Spain; the other two mentioned flow into Portugal. It is also the second-longest river in the Mediterranean basin, after the Nile.

Hispania was the Roman name for the Iberian Peninsula and its provinces. Under the Roman Republic, Hispania was divided into two provinces: Hispania Citerior and Hispania Ulterior. During the Principate, Hispania Ulterior was divided into two new provinces, Baetica and Lusitania, while Hispania Citerior was renamed Hispania Tarraconensis. Subsequently, the western part of Tarraconensis was split off, first as Hispania Nova, later renamed "Callaecia". From Diocletian's Tetrarchy onwards, the south of the remainder of Tarraconensis was again split off as Carthaginensis, and all of the mainland Hispanic provinces, along with the Balearic Islands and the North African province of Mauretania Tingitana, were later grouped into a civil diocese headed by a vicarius. The name Hispania was also used in the period of Visigothic rule.

Rechiar or Flavius Rechiarius was the third Suevic king of Gallaecia, from 448 until his death, and also the first one to be born in Gallaecia. He was one of the most innovative and belligerent of the Suevi monarchs. Hydatius, the contemporary bishop and chronicler from Galicia who is the sole contemporary source for biographical details of Rechiar, established his reputation as that of a barbarian with little sense of Roman law, culture, or custom; accusations already discredited, but very common at that time.

Christianity, less commonly referred to as Christianism, is an Abrahamic monotheistic religion based on the life and teachings of Jesus of Nazareth. It is the world's largest and most widespread religion with roughly 2.4 billion followers representing one-third of the global population. Its adherents, known as Christians, are estimated to make up a majority of the population in 157 countries and territories, and believe that Jesus is the Son of God, whose coming as the Messiah was prophesied in the Hebrew Bible and chronicled in the New Testament.

Liberté, égalité, fraternité, French for 'liberty, equality, fraternity', is the national motto of France and the Republic of Haiti, and is an example of a tripartite motto. Although it finds its origins in the French Revolution, it was then only one motto among others and was not institutionalized until the Third Republic at the end of the 19th century. Debates concerning the compatibility and order of the three terms began at the same time as the Revolution. It is also the motto of the Grand Orient and the Grande Loge de France.

In political science, the term Class conflict identifies the political tension and economic antagonism that exist among the social classes a society, because of socio-economic competition for resources among the social classes, between the rich and the poor. In the political and economic philosophies of Karl Marx and Mikhail Bakunin, class struggle is a central tenet and a practical means for effecting radical sociopolitical changes for the social majority, the working class.
