ImperiumIn ancient Rome, imperium was a form of authority held by a citizen to control a military or governmental entity. It is distinct from auctoritas and potestas, different and generally inferior types of power in the Roman Republic and Empire. One's imperium could be over a specific military unit, or it could be over a province or territory. Individuals given such power were referred to as curule magistrates or promagistrates. These included the curule aedile, the praetor, the consul, the magister equitum, and the dictator.
SuetoniusGaius Suetonius Tranquillus (ˈɡaːiʊs sweːˈtoːniʊs traŋˈkɥɪlːʊs), commonly referred to as Suetonius (swɪˈtoʊniəs ; c. AD 69 – after AD 122), was a Roman historian who wrote during the early Imperial era of the Roman Empire. His most important surviving work is a set of biographies of 12 successive Roman rulers from Julius Caesar to Domitian, properly titled De vita Caesarum. Other works by Suetonius concerned the daily life of Rome, politics, oratory, and the lives of famous writers, including poets, historians, and grammarians.
ArcadiusArcadius (Ἀρκάδιος ; 377 – 1 May 408) was Roman emperor from 383 to his death in 408. He was the eldest son of the Augustus Theodosius I (379-395) and his first wife Aelia Flaccilla, and the brother of Honorius (393-423). 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. Arcadius was born in 377 in Hispania, the eldest son of Theodosius I and Aelia Flaccilla, and brother of Honorius.
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.
TogaThe toga (ˈtoʊgə, ˈt̪ɔ.ɡa), a distinctive garment of ancient Rome, was a roughly semicircular cloth, between in length, draped over the shoulders and around the body. It was usually woven from white wool, and was worn over a tunic. In Roman historical tradition, it is said to have been the favored dress of Romulus, Rome's founder; it was also thought to have originally been worn by both sexes, and by the citizen-military. As Roman women gradually adopted the stola, the toga was recognized as formal wear for male Roman citizens.
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.
Valentinian IIIValentinian III (Placidus Valentinianus; 2 July 419 - 16 March 455) was Roman emperor in the West from 425 to 455. Made emperor in childhood, his reign over the Roman Empire was one of the longest, but was dominated by powerful generals vying for power amid civil wars and the invasions of Late antiquity's Migration Period, including the campaigns of Attila the Hun. He was the son of Galla Placidia and Constantius III, and as the great-grandson of Valentinian I (364-375) he was the last emperor of the Valentinianic dynasty.
LactantiusLucius Caecilius Firmianus signo Lactantius (c. 250 – c. 325) was an early Christian author who became an advisor to Roman emperor Constantine I, guiding his Christian religious policy in its initial stages of emergence, and a tutor to his son Crispus. His most important work is the Institutiones Divinae ("The Divine Institutes"), an apologetic treatise intended to establish the reasonableness and truth of Christianity to pagan critics. He is best known for his apologetic works, widely read during the Renaissance by humanists, who called Lactantius the "Christian Cicero".
DeciusGaius Messius Quintus Trajanus Decius ( 201 AD - June 251 AD), sometimes translated as Trajan Decius or Decius, was the emperor of the Roman Empire from 249 to 251. A distinguished politician during the reign of Philip the Arab, Decius was proclaimed emperor by his troops after putting down a rebellion in Moesia. In 249, he defeated and killed Philip near Verona and was recognized as emperor by the Senate afterwards.
KaiserKaiser is the German word for "emperor" (female, Kaiserin). In general, the German title in principle applies to rulers anywhere in the world above the rank of king (König). In English, the (untranslated) word Kaiser is mainly applied to the emperors of the unified German Empire (1871–1918) and the emperors of the Austrian Empire (1804–1918). During the First World War, anti-German sentiment was at its zenith; the term Kaiser—especially as applied to Wilhelm II, German Emperor—thus gained considerable negative connotations in English-speaking countries.
