Q:Information:  - 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.  - Sulla's second civil war was one of a series of civil wars of ancient Rome. It was fought between Lucius Cornelius Sulla and Gaius Marius the younger in 82 BC. Prelude. Sulla had achieved temporary control of Rome and Marius's exile to Africa through his first march on Rome, but departed soon afterwards to lead the First Mithridatic War. This departure allowed Gaius Marius and his son Gaius Marius the younger to return to Rome with an army and, with Lucius Cornelius Cinna, to wrest control of Rome back from Sulla's supporter Gnaeus Octavius during Sulla's absence. Based on the orders of Marius, some of his soldiers went through Rome killing the leading supporters of Sulla, including Octavius. Their heads were exhibited in the Forum. After five days, Cinna ordered his more disciplined troops to kill Marius's rampaging soldiers. All told some 100 Roman nobles had been murdered. Marius declared Sulla's reforms and laws invalid, officially exiled Sulla and had himself elected to Sulla's eastern command and himself and Cinna elected consuls for the year 86 BC. Marius died a fortnight after and Cinna was left in sole control of Rome.   - 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".  - Armenia ( tr. "Hayastan"), officially the Republic of Armenia (tr. "Hayastani Hanrapetutyun"), is a sovereign state in the South Caucasus region of Eurasia. Located in Western Asia on the "Armenian Highlands", it is bordered by Turkey to the west, Russia and Georgia to the north and Azerbaijan to the east, and Iran and Azerbaijan's exclave of Nakhchivan to the south.  - Mithridates VI or Mithradates VI, from Old Persian "Miradta", "gift of Mithra"; 13563 BC, also known as Mithradates the Great (Megas) and Eupator Dionysius, was king of Pontus and Armenia Minor in northern Anatolia (now Turkey) from about 12063 BC. Mithridates is remembered as one of the Roman Republics most formidable and successful enemies, who engaged three of the prominent generals from the late Roman Republic in the Mithridatic Wars: Lucius Cornelius Sulla, Lucius Licinius Lucullus and Gnaeus Pompey Magnus. He is often considered the greatest ruler of the Kingdom of Pontus.  - Gnaeus Pompeius Magnus (29 September 106 BC  28 September 48 BC), usually known in English as Pompey or Pompey the Great, was a military and political leader of the late Roman Republic. He came from a wealthy Italian provincial background, and his father had been the first to establish the family among the Roman nobility. Pompey's immense success as a general while still very young enabled him to advance directly to his first consulship without meeting the normal requirements for office. His success as a military commander in Sulla's Second Civil War resulted in Sulla bestowing the nickname "Magnus", "the Great", upon him. He was consul three times and celebrated three triumphs.  - The Third Mithridatic War (7363 BC) was the last and longest of three Mithridatic Wars and was fought between Mithridates VI of Pontus, who was joined by his allies, and the Roman Republic. The war ended in defeat for Mithridates, ending the Pontic Kingdom, and resulted in the Kingdom of Armenia becoming an allied client state of Rome.  - Lucius Cornelius Sisenna ( c. 120 -- 67 BC ) was a Roman soldier , historian , and annalist . He was killed in action during Pompey 's campaign against pirates after the Third Mithridatic War . Sisenna had been commander of the forces on the coast of Greece . He was the author of a history in twenty - three books , all of which have been lost , save a few fragments . Sallust is said to have begun historical work as a continuation of Sisenna 's . Sisenna also translated a collection of erotic and picaresque tales by Aristides of Miletus entitled Milesiae fabulae , which was said to have served as a model for Petronius ' Satyricon .  - Rome is a city and special "comune" (named "Roma Capitale") in Italy. Rome is the capital of Italy and of the Lazio region. With 2,870,336 residents in , it is also the country's largest and most populated "comune" and fourth-most populous city in the European Union by population within city limits. The Metropolitan City of Rome has a population of 4.3 million residents. The city is located in the central-western portion of the Italian Peninsula, within Lazio (Latium), along the shores of Tiber river. The Vatican City is an independent country geographically located within the city boundaries of Rome, the only existing example of a country within a city: for this reason Rome has been often defined as capital of two states.     Given the paragraphs above, decide what entity has the relation 'country of citizenship' with 'ancient rome'.
