The '''Roman Empire''' was an ancient state centred on the city of [[Rome]] and the [[Mediterranean Sea]]. It developed from the Roman Republic and began in 27 BC, when Octavian received the title Augustus and became the first [[Roman emperor]]. The empire governed the [[Italian Peninsula]], western and southern [[Europe]], the [[Balkans]], [[Anatolia]], the [[Levant]], parts of western Asia, and the Mediterranean coast of North Africa.<ref name="italy-history"/>

At its greatest territorial extent under Emperor Trajan in AD 117, Roman territory stretched from [[Britain]] and the [[Iberian Peninsula]] to Mesopotamia, and from the Rhine and Danube frontiers to Egypt and the Sahara. Roman rule joined these regions through provincial government, taxation, military garrisons, roads, ports, maritime routes, and a shared legal system. The Mediterranean formed the main transport area between the empire's provinces and cities.<ref name="mediterranean-history"/>

The empire was permanently divided into western and eastern administrative courts after the death of [[Theodosius I]] in AD 395. The Western Roman Empire ended during the fifth century, while the eastern state continued from [[Constantinople]] and is commonly called the [[Byzantine Empire]].

== History ==
Rome expanded beyond central Italy during the period of the Roman Republic. By the first century BC, Roman authority covered the Italian Peninsula, much of the western Mediterranean, Greece, parts of the Balkans, North Africa, and territories in western Asia. Military expansion brought wealth and land into Roman control, but it also increased political competition between commanders and contributed to a series of civil wars.

Julius Caesar became dictator after defeating his opponents but was assassinated in 44 BC. His adopted heir Octavian joined Mark Antony and Marcus Aemilius Lepidus in the Second Triumvirate. The alliance defeated the assassins of Caesar before breaking apart. Octavian defeated Antony and Cleopatra at the Battle of Actium in 31 BC and annexed Egypt the following year.

In 27 BC, the Roman Senate granted Octavian the title Augustus. He retained republican offices and institutions while holding control over the army, important provinces, taxation, and senior appointments. This system became known as the Principate. The Senate, magistrates, and assemblies continued to exist, but political authority increasingly depended on the emperor.

The reign of Augustus began a long period of internal stability commonly called the Pax Romana. The Julio-Claudian, Flavian, and Nerva–Antonine dynasties extended Roman administration and developed cities, roads, aqueducts, ports, and frontier defences. Britain was invaded under Claudius, while Trajan conquered Dacia and temporarily extended Roman authority into Mesopotamia. Roman expansion incorporated Greece and much of the Balkans into a political and transport system based around the Mediterranean.<ref name="southern-europe-history"/><ref name="balkans-history"/>

Territorial expansion largely stopped after the reign of Trajan. [[Hadrian]] withdrew from several eastern conquests and concentrated on securing the frontiers. Defensive systems were established along the Rhine, Danube, northern Britain, North Africa, and the eastern border with the Parthian and later Sasanian empires.

The empire entered a period of political instability during the third century. Emperors were frequently removed by military revolt, frontier invasions increased, and separate governments developed in Gaul and the eastern provinces. Economic disruption, disease, civil war, and pressure on the army weakened central authority. Emperor [[Aurelian]] restored the breakaway territories during the 270s.

[[Diocletian]] reorganized the government after becoming emperor in AD 284. He divided imperial responsibility among several rulers in a system known as the Tetrarchy. The provinces were reorganized into smaller administrative units, taxation was revised, and the size of the government and military increased. The Tetrarchy did not create a lasting system of peaceful succession, and renewed civil wars followed Diocletian's retirement.

[[Constantine the Great]] defeated his rivals and reunited the empire under one ruler. In AD 330, he inaugurated Constantinople on the site of Byzantium as an imperial capital. Its location on the [[Bosporus]] placed it between the Balkans, Anatolia, the Black Sea, and the eastern Mediterranean. Anatolia and Thrace later became central territories of the eastern Roman administration.<ref name="turkey-history"/>

Theodosius I was the final emperor to govern both the western and eastern courts. After his death on 17 January AD 395, authority passed to his sons. [[Honorius]] governed the west, while [[Arcadius]] governed the east. The two administrations continued to regard themselves as parts of the same Roman state but developed separate courts, armies, finances, and political interests.

== Government ==
The emperor was the head of the Roman state, commander of the armed forces, chief source of senior appointments, and an important religious authority. Imperial power depended on control of the army, recognition by political institutions, and support from provincial and court officials. Succession was not governed by a fixed constitutional rule. Emperors gained power through adoption, family inheritance, appointment by a predecessor, military proclamation, or victory in civil war.

The Roman Senate continued from the republican period. It supervised some provinces, issued decrees, confirmed honours, and provided officials for the imperial administration. Its independent political authority declined as emperors gained greater control over legislation, finance, provincial appointments, and the military.

The empire was divided into provinces governed by officials responsible for taxation, justice, public order, and military administration. Some provinces were supervised by the Senate, while provinces containing large military forces were controlled directly by the emperor. Local councils governed many cities and collected taxes on behalf of the state.

Roman law developed through statutes, senatorial decisions, imperial decrees, legal opinions, and court practice. Provincial legal traditions continued in some areas, but Roman citizenship determined access to several legal rights and procedures. In AD 212, Emperor [[Caracalla]] granted Roman citizenship to almost all free inhabitants of the empire.

The administrative centre remained in Rome during the early imperial period. Later emperors spent more time near military frontiers and established courts in cities including Mediolanum, Trier, Nicomedia, Antioch, Ravenna, and Constantinople. This allowed the government to respond more quickly to military and administrative problems outside Italy.

== Military ==
The Roman army consisted mainly of legions, auxiliary formations, naval forces, and frontier units. Legionaries were Roman citizens, while auxiliary soldiers were originally recruited from provincial populations without citizenship. Auxiliary veterans commonly received citizenship after completing their service.

The army defended the frontiers, suppressed revolts, protected roads, supported provincial officials, and took part in imperial expansion. Legions were stationed along the Rhine and Danube, in Britain, North Africa, Egypt, the Balkans, and the eastern provinces. Naval forces protected coastal routes, transported troops, and supported operations along rivers and seas.

Fortifications, watchtowers, military roads, and permanent camps formed frontier systems often described as the ''limes''. Some frontiers followed rivers or other natural barriers. Others consisted of forts and controlled routes rather than a continuous wall.

Roman military roads connected Italy with the provinces. The [[Via Egnatia]] crossed the Balkans from Dyrrachium, present-day [[Durrës]], toward Thessalonica and Constantinople. Maritime routes across the [[Ionian Sea]] connected Italy with Epirus, Greece, and the eastern provinces.<ref name="ionian-history"/>

The army also influenced imperial politics. Soldiers and commanders proclaimed several emperors, especially during civil wars and the third-century crisis. Rival military claims often divided the empire and forced emperors to spend much of their reigns campaigning near the frontiers.

== Economy and society ==
The Roman economy was based on agriculture, taxation, trade, mining, craft production, construction, and military supply. Grain, olive oil, wine, metals, pottery, textiles, livestock, and manufactured goods moved between provinces through roads, rivers, and maritime routes. Rome and other large cities depended on organised shipments of food from North Africa, Egypt, Sicily, and other agricultural regions.

The Mediterranean was the main commercial route of the empire. Ports connected inland roads and river systems with shipping between Italy, Greece, Egypt, North Africa, Iberia, Gaul, Anatolia, and the Levant.<ref name="mediterranean-history"/> Coinage was issued in gold, silver, bronze, and other metals. The denarius was an important silver coin during the early empire, while the gold solidus became central to the later imperial monetary system.

Roman society was legally and economically unequal. The senatorial and equestrian orders formed the highest recognised social ranks. Below them were local elites, citizens, freed people, provincial communities, rural workers, soldiers, artisans, merchants, and labourers. Enslaved people worked in households, agriculture, mines, workshops, transport, administration, and construction. Manumission allowed some enslaved people to become freed citizens, although social and legal restrictions remained.

Cities served as centres of administration, taxation, commerce, religion, and public life. Roman urban development included forums, temples, baths, theatres, amphitheatres, aqueducts, sewers, markets, and defensive walls. Local governments financed public buildings and organised civic services, festivals, and food distribution.

== Religion and culture ==
Roman religion included the worship of traditional Roman gods, household deities, the imperial cult, and religious traditions adopted from conquered regions. Provincial communities continued to worship Greek, Egyptian, Celtic, Germanic, Semitic, and other local deities. Religious practices varied across the empire and often combined Roman and regional traditions.

Judaism remained established in communities across Judea and many Mediterranean cities. Christianity developed in the first century AD and spread through urban and trade networks. Christians faced periods of local and imperial persecution, although the scale and enforcement of these measures differed between reigns and provinces.

Constantine and Licinius ended official restrictions on Christian worship in AD 313. Constantine supported the Church, funded religious buildings, and called the Council of Nicaea in AD 325. Emperor Theodosius I made Nicene Christianity the official form of imperial Christianity in AD 380. Traditional religious practices continued for a time but were increasingly restricted by later imperial governments.

Latin was the main language of government, law, and the army in the western provinces. Greek remained dominant in the eastern Mediterranean and was widely used in administration, education, literature, philosophy, and commerce. Many provincial languages continued to be spoken alongside Latin and Greek.

Roman culture developed from Italian, Etruscan, Greek, and provincial traditions. Roman writers, jurists, engineers, architects, physicians, and administrators produced works that continued to influence later European and Mediterranean societies. Public architecture included roads, bridges, aqueducts, basilicas, baths, temples, theatres, arenas, and defensive works.

== Division and legacy ==
The western administration weakened during the fifth century as military commanders, court officials, and Germanic federate forces competed for control. Roman authority was lost in Britain, Gaul, Hispania, and North Africa. In AD 476, the Germanic commander [[Odoacer]] removed the western emperor [[Romulus Augustulus]] and governed Italy as king.

The eastern administration survived with Constantinople as its capital. Its inhabitants and rulers continued to identify their state as Roman. It retained Roman government, law, imperial titles, and political institutions while Greek gradually became the main administrative language. This eastern Roman state is commonly known as the Byzantine Empire and continued until the Ottoman capture of Constantinople in 1453.<ref name="greece-history"/><ref name="turkey-history"/>

Roman institutions influenced later systems of law, government, taxation, military organisation, urban planning, architecture, language, and religion. Latin developed into the Romance languages and remained important in law, education, religion, and scholarship. Roman roads, city plans, bridges, walls, and aqueducts continued to shape settlement and transport across former imperial territory.

Later rulers and states used Roman titles and political traditions to support claims of imperial authority. The Byzantine emperors ruled as Roman emperors, while the [[Holy Roman Empire]] adopted Roman imperial terminology in western Europe. Rome also remained a major religious centre through the development of the Roman Catholic Church.
