Late antiquityLate antiquity was the time of transition from classical antiquity to the Middle Ages, generally spanning the 4th–8th century in Europe and adjacent areas bordering the Mediterranean Basin. The popularization of this periodization in English has generally been credited to historian Peter Brown, after the publication of his seminal work The World of Late Antiquity (1971). Precise boundaries for the period are a continuing matter of debate, but Brown proposes a period between the 3rd and 8th centuries AD.
Byzantine EmpireThe Byzantine Empire, also referred to as the Eastern Roman Empire, was the continuation of the Roman Empire primarily in its eastern provinces during Late Antiquity and the Middle Ages, when its capital city was Constantinople. It survived the fall of the Western Roman Empire in the 5th century AD and continued to exist until the fall of Constantinople to the Ottoman Empire in 1453. During most of its existence, the empire remained the most powerful economic, cultural, and military force in the Mediterranean world.
FranksThe Franks (Franci or gens Francorum; Francs) were originally a Germanic people who lived near the Lower Rhine, on the northern frontier of the late Roman Empire, but they successfully expanded their power and influence during the Middle Ages, until much of the population of western Europe, particularly in or near France, were commonly described as Franks, for example in the context of their joint efforts during the crusades starting in the 11th century.
HispaniaHispania (Hispānia hɪsˈpaːnia, isˈpanja; nearly identically pronounced in Spanish, Portuguese, Catalan, and Italian) 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.
Roman navyThe naval forces of the ancient Roman state (classis) were instrumental in the Roman conquest of the Mediterranean Basin, but it never enjoyed the prestige of the Roman legions. Throughout their history, the Romans remained a primarily land-based people and relied partially on their more nautically inclined subjects, such as the Greeks and the Egyptians, to build their ships. Because of that, the navy was never completely embraced by the Roman state, and deemed somewhat "un-Roman".
MoesiaMoesia (ˈmiːʃə,-siə,-ʒə; Latin: Moesia; Moisía) was an ancient region and later Roman province situated in the Balkans south of the Danube River, which included most of the territory of modern eastern Serbia, Kosovo, north-eastern Albania, northern parts of North Macedonia (Moesia Superior), Northern Bulgaria, Romanian Dobruja and small parts of Southern Ukraine (Moesia Inferior). In ancient geographical sources, Moesia was bounded to the south by the Haemus (Balkan Mountains) and Scardus (Šar) mountains, to the west by the Drinus (Drina) river, on the north by the Donaris (Danube) and on the east by the Euxine (Black Sea).
AuxiliaThe Auxilia (au̯kˈs̠ɪlia, lit. "auxiliaries") were introduced as non-citizen troops attached to the citizen legions by Augustus after his reorganisation of the Imperial Roman army from 27 BC. By the 2nd century, the Auxilia contained the same number of infantry as the legions and, in addition, provided almost all of the Roman army's cavalry (especially light cavalry and archers) and more specialised troops. The auxilia thus represented three-fifths of Rome's regular land forces at that time.
Roman provinceThe Roman provinces (Latin: provincia, pl. provinciae) were the administrative regions of Ancient Rome outside Roman Italy that were controlled by the Romans under the Roman Republic and later the Roman Empire. Each province was ruled by a Roman appointed as governor. For centuries it was the largest administrative unit of the foreign possessions of ancient Rome. With the administrative reform initiated by Diocletian, it became a third level administrative subdivision of the Roman Empire, or rather a subdivision of the imperial dioceses (in turn subdivisions of the imperial prefectures).
Roman legionThe Roman legion (legiō, ˈɫɛɡioː), the largest military unit of the Roman army, comprised 5,200 infantry and 300 equites (cavalry) in the period of the Roman Republic (509 BC–27 BC) and 5,600 infantry and 200 auxilia in the period of the Roman Empire (27 BC – AD 476). The size of a typical legion varied throughout the history of ancient Rome, with complements ranging from 4,200 legionaries and 300 equites (drawn from the wealthier classes – in early Rome all troops provided their own equipment) in the Republic, to 5,500 in the Imperial period.
