Given the question: Information:  - The Battle of the Margus was fought in July 285 between the armies of Roman Emperors Diocletian and Carinus in the valley of the Margus River (today Great Morava) in Moesia (present day Serbia).  - In the later Roman Empire, bagaudae (also spelled bacaudae) were groups of peasant insurgents who arose during the Crisis of the Third Century, and persisted until the very end of the western Empire, particularly in the less-Romanised areas of Gallia and Hispania, where they were "exposed to the depredations of the late Roman state, and the great landowners and clerics who were its servants".   - Carinus (died 285) was Roman Emperor from 283 to 285. The elder son of emperor Carus, he was first appointed "Caesar" and in the beginning of 283 co-emperor of the western portion of the empire by his father. Official accounts of his character and career have been filtered through the propaganda of his successful opponent, Diocletian.  - Hispania was the Roman name for the Iberian Peninsula. Under the Republic, Hispania was divided into two provinces: Hispania Citerior and Hispania Ulterior. During the Principate, Hispania Ulterior was divided into two new provinces, Baetica and Lusitania, while Hispania Citerior was renamed Tarraconensis. Subsequently, the western part of Tarraconensis was split off, first as Hispania Nova, later renamed Callaecia (or Gallaecia, whence modern Galicia). From Diocletian's Tetrarchy (AD 284) onwards, the south of remaining Tarraconensis was again split off as Carthaginensis, and probably then too the Balearic Islands and all the resulting provinces formed one civil diocese under the "vicarius" for the Hispaniae (that is, the Celtic provinces). The name, Hispania, was also used in the period of Visigothic rule.  - 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.  - Numerian (died 20 November 284) was Roman Emperor from 283 to 284 with his older brother Carinus. They were sons of Carus, a general raised to the office of praetorian prefect under Emperor Probus in 282.  - The Roman emperor was the ruler of the Roman Empire during the imperial period (starting in 27 BC). 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".  - The Crisis of the Third Century, also known as Military Anarchy or the Imperial Crisis (AD 235284), was a period in which the Roman Empire nearly collapsed under the combined pressures of invasion, civil war, plague, and economic depression. The Crisis began with the assassination of Emperor Severus Alexander by his own troops in 235, initiating a 50-year period in which there were at least 26 claimants to the title of Emperor, mostly prominent Roman army generals, who assumed imperial power over all or part of the Empire. The same number of men became accepted by the Roman Senate as emperor during this period and so became legitimate emperors.  - Diocletian, born Diocles (244312), was a Roman emperor from 284 to 305. Born to a family of low status in the Roman province of Dalmatia, Diocletian rose through the ranks of the military to become cavalry commander to the Emperor Carus. After the deaths of Carus and his son Numerian on campaign in Persia, Diocletian was proclaimed emperor. The title was also claimed by Carus' other surviving son, Carinus, but Diocletian defeated him in the Battle of the Margus. Diocletian's reign stabilized the empire and marks the end of the Crisis of the Third Century. He appointed fellow officer Maximian as Augustus, co-emperor, in 286.  - Maximian (c. 250  c. July 310) was Roman Emperor from 286 to 305. He was "Caesar" from 285 to 286, then "Augustus" from 286 to 305. He shared the latter title with his co-emperor and superior, Diocletian, whose political brain complemented Maximian's military brawn. Maximian established his residence at Trier but spent most of his time on campaign. In the late summer of 285, he suppressed rebels in Gaul known as the Bagaudae. From 285 to 288, he fought against Germanic tribes along the Rhine frontier. Together with Diocletian, he launched a scorched earth campaign deep into Alamannic territory in 288, temporarily relieving the Rhine provinces from the threat of Germanic invasion.  - Augustus (23 September 63 BC  19 August 14 AD) was the founder of the Roman Principate and considered the first Emperor, controlling the Roman Empire from 27 BC until his death in AD 14.  - Aelianus was together with Amandus the leader of an insurrection of Gallic peasants , called Bagaudae , in the reign of Diocletian . It was put down by the Caesar Maximianus Herculius in 285 .  - Carus (c. 222  July or August 283) was Roman Emperor from 282 to 283, and was 60 at ascension. During his short reign, Carus fought the Germanic tribes and Sarmatians along the Danube frontier with success. He brought stability in the empire and died in 283 aged 61.    What object entity has the relation of 'date of death' with the subject 'aelianus '?   Choices: - 14  - 19 august 14  - 20  - 222  - 23  - 235  - 244  - 250  - 26  - 27  - 283  - 284  - 285  - 286  - 31  - 310  - 312  - 44  - 50  - 500  - 90  - july 285
The answer is:
286
