The emperors used a variety of different titles throughout history. Often when a given Roman is described as becoming "emperor" in English, it reflects his taking of the title "Augustus" or "Caesar". Another title often used was "imperator", originally a military honorific. Early Emperors also used the title "princeps" (first citizen). Emperors frequently amassed republican titles, notably "Princeps Senatus", "Consul" and "Pontifex Maximus"., Arcadius (1 January 377  1 May 408) was Eastern Roman Emperor from 383 to 408. He was the eldest son of Theodosius I and his first wife Aelia Flaccilla, and brother of the Western Emperor Honorius. A weak ruler, his reign was dominated by a series of powerful ministers and by his wife, Aelia Eudoxia., Aelia Flavia Flaccilla (31 March 356  386), was a Roman empress and first wife of the Roman Emperor Theodosius I. She was of Hispanian Roman descent. During her marriage to Theodosius, she gave birth to two sons  future Emperors Arcadius and Honorius  and a daughter, Aelia Pulcheria. She was titled "Augusta", as her coinage shows., The Goths were an East Germanic people, two of whose branches, the Visigoths and the Ostrogoths, played an important role in the fall of the Western Roman Empire and the emergence of Medieval Europe. The Goths dominated a vast area, which at its peak under the Germanic king Ermanaric and his sub-king Athanaric possibly extended all the way from the Danube to the Don, and from the Black Sea to the Baltic Sea., The Roman Empire (Koine and Medieval Greek:   , tr. ) was the post-Roman Republic period of the ancient Roman civilization, characterized by government headed by emperors and large territorial holdings around the Mediterranean Sea in Europe, Africa and Asia. The city of Rome was the largest city in the world BC AD, with Constantinople (New Rome) becoming the largest around 500 AD, and the Empire's populace grew to an estimated 50 to 90 million inhabitants (roughly 20% of the world's population at the time). The 500-year-old republic which preceded it was severely destabilized in a series of civil wars and political conflict, during which Julius Caesar was appointed as perpetual dictator and then assassinated in 44 BC. Civil wars and executions continued, culminating in the victory of Octavian, Caesar's adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavian's power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power and the new title "Augustus", effectively marking the end of the Roman Republic., The Danube (, known by various names in other languages) is Europe's second-longest river, after the Volga River, and also the longest river in the European Union region. It is located in Central and Eastern Europe., Theodosius I (11 January 347  17 January 395), also known as Theodosius the Great, was Roman Emperor from AD 379 to AD 395. Theodosius was the last emperor to rule over both the eastern and the western halves of the Roman Empire. On accepting his elevation, he campaigned against Goths and other barbarians who had invaded the empire. He failed to kill, expel, or entirely subjugate them, and after the Gothic War, they established a homeland south of the Danube, in Illyricum, within the empire's borders. He fought two destructive civil wars, in which he defeated the usurpers Magnus Maximus and Eugenius at great cost to the power of the empire., Flavius Eugenius (died 6 September 394) was a usurper in the Western Roman Empire (392394) against Emperor Theodosius I. Though himself a Christian, he was the last Emperor to support Roman polytheism., Flavius Rufinus ( died November 27 , 395 ) was a 4th - century Eastern Roman Empire statesman of Gaulish extraction who served as Praetorian prefect of the East for the emperor Theodosius I , as well as his son Arcadius , under whom Rufinus was the actual power behind the throne . He was the subject of the verse invective In Rufinum by the western court poet Claudian ., Magnus Maximus (ca. 335  August 28, 388) was Western Roman Emperor from 383 to 388., Subject: rufinus , Relation: place_of_death, Options: (A) africa (B) august (C) black sea (D) central (E) constantinople (F) danube (G) don (H) imperial (I) march (J) roman (K) roman empire (L) rome (M) sea
