Context: Consul (abbrev. "cos."; Latin plural "consules") was the title of one of the chief magistrates of the Roman Republic, and subsequently a somewhat significant title under the Roman Empire. The title was also used in other city states and also revived in modern states, notably in the First French Republic. The relating adjective is consular, from the "consularis"., The Roman Republic was the era of ancient Roman civilization beginning with the overthrow of the Roman Kingdom, traditionally dated to 509 BC, and ending in 27 BC with the establishment of the Roman Empire. It was during this period that Rome's control expanded from the city's immediate surroundings to hegemony over the entire Mediterranean world., A title is a prefix or suffix added to someone's name in certain contexts. It may signify either veneration, an official position or a professional or academic qualification. In some languages, titles may be inserted before a last name (for example, "Graf" in German, Cardinal in Catholic usage or clerical titles such as Archbishop). Some titles are hereditary., 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., Consularis is a Latin adjective indicating something pertaining to the consular office. In Ancient Rome it was a title given to those senators who held consular rank, i.e. who had served as consuls or who had received the rank as a special honour. In Late Antiquity, the title became also a gubernatorial rank for provincial governors., Quintus Fufius Calenus ( died 40 BC ) was a Roman general , and consul in 47 BC. As tribune of the people in 61 BC , he was chiefly instrumental in securing the acquittal of the notorious Publius Clodius when charged with having profaned the mysteries of Bona Dea ( Cicero , Ad . Att . 1.16 ) . In 59 BC Calenus was praetor , and brought forward a law that the senators , knights , and tribuni aerarii , who composed the judices , should vote separately , so that it might be known how they gave their votes ( Cassius Dio xxxviii . 8 ) . He fought in Gaul ( 51 BC ) and Spain ( 49 BC ) under Julius Caesar , who , after he had crossed over to Greece ( 48 BC ) , sent Calenus from Epirus to bring over the rest of the troops from Italy . On the passage to Italy , most of the ships were captured by Bibulus and Calenus himself escaped with difficulty . In 47 BC , he was raised to the consulship through the influence of Caesar . After the death of the dictator , he joined Mark Antony , for whom he commanded eleven legions in the north of Italy . Calenus died in 40 BC , while stationed with his army at the foot of the Alps , just as he was on the point of marching against Octavian ; but Calenus ' son handed over the legions to the future emperor ., Subject: quintus fufius calenus, Relation: country_of_citizenship, Options: (A) academic (B) ancient rome (C) egypt (D) french republic (E) roman empire (F) roman republic
