Peoples, allies and opponents 93
Aedui

Long-standing Roman partners whose internal politics and rivalry with the Arverni and Sequani shaped Caesar's intervention; factions and allegiance shifted during the conquest.
Republic, especially 3rd-2nd centuries BCE · Greece
Distinct Greek federations alternated between Roman partnership and resistance; defeat and intervention transformed their autonomy without ending Greek civic institutions.
Red Sea kingdom engaged in trade, Christian kingship and Arabian intervention; its contacts with Rome included diplomacy and commerce rather than Roman provincial subordination.
Third century CE onward · Upper Rhine and southwest Germany
A changing confederation central to Roman frontier warfare, notably Strasbourg 357 CE; Roman defeats and treaties did not create an unchanging political bloc.
Fourth-fifth centuries CE and later · Steppe Gaul Iberia and Africa
Iranian-speaking groups with diverse trajectories: some served Rome, others joined Vandals and other migrating coalitions, while communities remained in the Caucasus.
Kingdoms and noble houses navigated Roman and Iranian intervention; Armenia was often a contested partner rather than simply a Roman province or Persian possession.
Powerful people of the Auvergne; Vercingetorix led a broad coalition against Caesar 52 BCE. Their subsequent civitas retained regional significance under Roman rule.

Steppe-centered khaganate employing mixed populations and pressuring eastern Roman frontiers; allied with Persia during the siege of Constantinople 626 CE.
Privileged Roman military recruiting community that revolted under Julius Civilis 69-70 CE; their history demonstrates that service and rebellion could involve the same networks.

Distinct groups and political formations involved in raids, treaties and frontier settlement south of Egypt; religious and diplomatic transitions differed by community.
Late Republic and Empire · Crimea and Taman peninsula
Black Sea client monarchy connected to Pontic grain, dynastic politics and Roman patronage; Roman recognition did not mean routine direct provincial government.
Large northern British grouping divided by rival rulers, including pro-Roman Cartimandua and resisting Venutius; Roman conquest followed shifting internal and external alliances.
An umbrella term for varied island communities and kingdoms, encountered by Caesar and later conquered in part under Claudius; local identities and institutions remained important.
Fifth-sixth centuries CE · Rhine and southeastern Gaul
Groups devastated near the Rhine and resettled in Sapaudia developed a kingdom integrated into Frankish expansion; federate service formed part of their history.
Roman name for northern groups beyond permanent provincial control, including opponents in Agricola's campaigns; geography and political coalitions should not be treated as static.
Communities around Capua and other wealthy centers entered differing relationships with Rome; Capua's Hannibalic alliance ended in severe Roman punishment 211 BCE.
Late Republic and Augustan Empire · Northern Iberia
Northern peoples subjected during Augustus' protracted wars 29-19 BCE, with later military recruitment and mining economies; provincial integration followed continuing coercion and accommodation.

Late Republic and 1st century CE · Southeastern Britain
Neighboring political communities central to Caesar's contacts and Claudian conquest; dynastic power and relations with Rome changed before annexation.
Kingdom in the Caucasus, distinct from Iberian Spain, whose rulers negotiated with Rome and Iranian powers; religion and strategic passes shaped those relations.

Early Rome to late Republic · Etruria and northern/central Italy
Urban communities with their own language, religious expertise and political histories; Rome fought and incorporated different Etruscan cities rather than conquering one unified nation.
Third century CE onward · Lower Rhine and northern Gaul

Distinct coastal groups involved in Roman tribute, recruitment, naval operations and conflict; tidal landscapes shaped both imperial campaigns and local livelihoods.
Roman label for diverse groups south of the main coastal settlements, appearing as cavalry, allies and opponents; it does not denote one continuous state.

A linguistic and ancient ethnographic grouping encompassing numerous changing societies. Roman usage did not identify one state or a uniform permanent enemy.
Principally 6th century CE · Syrian and Arabian frontier
Arab ruling coalition allied with eastern Rome, important in warfare and Christian patronage; the labels Ghassanid and Jafnid do not describe every Arab allied group.
Third century CE onward · Black Sea Balkans and western kingdoms
Changing group identities and coalitions connected raids, Roman service, migration and successor states; later Visigoth/Ostrogoth labels should not be projected unchanged into every earlier episode.
Independent or dependent poleis such as Tarentum and Syracuse alternated between alliance, resistance and incorporation; Greek civic and cultural life survived Roman conquest.

A mobile imperial coalition incorporating many peoples; Attila negotiated tribute and fought both eastern and western Roman powers before the coalition fragmented.
First-fourth centuries CE · Plain east of middle Danube

Roman and Greek umbrella labels encompassed distinct communities; Dalmatae were one important group, while later Illyricum was an administrative and military designation.

Republic and early Empire; annexed 106 CE · Southern Levant and Arabia
Kingdom centered on Petra and Bostra linked caravan commerce, agriculture and royal power; annexation formed Arabia Petraea while local communities continued.
People prominent in the battle at the Sabis against Caesar and later resistance; Roman narration of their martial character is a situated source portrayal.
11th-12th centuries CE · Southern Italy Sicily and Balkans
Later orientation: western rulers who displaced eastern Roman authority in southern Italy and campaigned in the Balkans, sometimes negotiating as well as fighting.
North African kingdoms supplied cavalry and alternated among rival alliances; Massinissa backed Rome, Jugurtha fought it, and royal territories were progressively annexed.

Late Roman collective name for northern peoples, prominent in frontier warfare and later kingdoms; not a single timeless tribe identical to all earlier Caledonians.
Republic to 30 BCE · Egypt and eastern Mediterranean
Dynasty ruling Egypt negotiated loans, alliances and Roman intervention; Cleopatra VII's defeat ended royal independence and made Egypt an imperial province.
Neighbors often allied with Marcomanni or Sarmatian groups, appearing in wars, treaties and client kingship; their political relationship with Rome varied across reigns.
Neighboring central Italian people prominent in Roman origin traditions and historical incorporation; Sabine identity persisted within an increasingly Roman political landscape.
Religious community centered on Mount Gerizim with distinct traditions and political experiences; late Roman revolts and imperial policies profoundly affected its communities.
Confederated highland peoples who fought Rome in successive wars and later the Social War; defeat did not erase their regional communities or political resistance.

Ardashir's dynasty replaced Arsacid rule and became Rome's main eastern rival, conducting diplomacy and warfare across Mesopotamia, Armenia and the Levant.
Late Roman and early medieval periods · North Sea coasts and Britain

Latin label associated with raiders and settlers from Ireland, later linked with Gaelic polities in Britain; it differs from modern nationality terminology.
Republic, especially 2nd-1st centuries BCE · Eastern Mediterranean and Asia
Hellenistic monarchy defeated in the Roman-Syrian War; territorial losses and dynastic struggles preceded Pompey's annexation of its Syrian remnant 64 BCE.
Later orientation: a Turkic-led imperial and dynastic world whose victory at Manzikert 1071 CE preceded major Anatolian political change; it was not a classical Roman tribe.
Names for differing pre-Roman Sicilian populations whose histories interacted with Greek and Punic colonization; they should not be collapsed into a single indigenous state.
Sixth century CE onward · North of Danube and Balkans
Labels in late Roman sources for varied communities involved in raiding, settlement and military alliances; neither name describes a single centralized state.
Early Empire to sixth century CE · Central Europe and northwestern Iberia
Ancient umbrella name and later specific political formations; a Suevic kingdom developed in Gallaecia after the Rhine crossings and was annexed by Visigoths 585 CE.
