Roman EmpireThe Roman Empire was the post-Republican state of ancient Rome. It included territory around the Mediterranean in Europe, North Africa, and Western Asia, and was ruled by emperors. The adoption of Christianity as the state church in 380 and the fall of the Western Roman Empire conventionally marks the end of classical antiquity and the beginning of the Middle Ages.
Ancient RomeIn modern historiography, ancient Rome refers to Roman civilisation from the founding of the Italian city of Rome in the 8th century BC to the collapse of the Western Roman Empire in the 5th century AD. It encompasses the Roman Kingdom (753–509 BC), Roman Republic (509–27 BC), and Roman Empire (27 BC–476 AD) until the fall of the western empire. Ancient Rome began as an Italic settlement, traditionally dated to 753 BC, beside the River Tiber in the Italian Peninsula.
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.
Anno DominiThe terms anno Domini (AD) and before Christ (BC) are used to label or number years in the Julian and Gregorian calendars. The term anno Domini is Medieval Latin and means "in the year of the Lord" but is often presented using "our Lord" instead of "the Lord", taken from the full original phrase "anno Domini nostri Jesu Christi", which translates to "in the year of our Lord Jesus Christ". The form "BC" is specific to English, and equivalent abbreviations are used in other languages: the Latin form, rarely used in English, is Ante Christum natum (ACN) or Ante Christum (AC).
RomeRome (Italian and Latin: Roma ˈroːma) is the capital city of Italy. It is also the capital of the Lazio region, the centre of the Metropolitan City of Rome, and a special comune named Comune di Roma Capitale. With 2,860,009 residents in , Rome is the country's most populated comune and the third most populous city in the European Union by population within city limits. The Metropolitan City of Rome, with a population of 4,355,725 residents, is the most populous metropolitan city in Italy.
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).
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.
TrajanTrajan (ˈtreɪdʒən ; Caesar Nerva Traianus; 18 September 53 11 August 117) was Roman emperor from 98 to 117. Trajan was born and raised in Italica, close to modern Seville in present-day Spain, a small Roman municipium of Hispania Baetica founded by Scipio as an Italic settlement; his branch of the Ulpia gens, the Ulpii Traiani, came from the town of Tuder in the Umbria region of Italia. Trajan's father, Marcus Ulpius Traianus, also from Italica, was a senator. Trajan rose to prominence during the reign of Domitian.
Constantine the GreatConstantine I (27 February 272 - 22 May 337), also known as Constantine the Great, was Roman emperor from AD 306 to 337. He was the first emperor to convert to Christianity. Born in Naissus, Dacia Mediterranea (now Niš, Serbia), he was the son of Flavius Constantius, a Roman army officer of Illyrian origin who had been one of the four rulers of the Tetrarchy. His mother, Helena, was a Greek woman of low birth and a Christian. Later canonized as a saint, she is traditionally attributed with the conversion of her son.

He was born in Italica, close to modern Seville in Spain, a small Roman municipium of Hispania Baetica founded by Scipio as an Italic settlement; his branch of the Aelia gens, the Aeli Hadriani, came from the town of Hadria. Hadrian was a member of the Nerva–Antonine dynasty. Early in his career, Hadrian married Vibia Sabina, grandniece of the ruling emperor, Trajan.
