• Claudius dies of plague in Sirmium while preparing to fight the Vandals and Sarmatians, who have invaded Pannonia. He is succeeded by his brother Quintillus, who briefly holds power over the Roman Empire.
• Victorinus besieges and sacks the city of Autun, which had declared allegiance to Claudius.
• Lucius Domitius Aurelianus (or Aurelian), the cavalry commander who distinguished himself in the previous year at the Battle of Naissus (Serbia), usurps power in Sirmium and marches against Quintillus in Aquileia. Quintillus commits suicide.

Roman Empire

• After an indecisive battle, Emperor Aurelian defeats the Vandals, and forces them from Pannonia, and across the Danube.
• Battle of Placentia: The Iuthungi invade Italy and sack the city of Piacenza. A Roman army under Emperor Aurelian is ambushed and defeated.
  • Battle of Fano: The Iuthungi move towards a defenseless Rome. Aurelian rallies his men and defeats the Germanic tribes on the Metauro River, just inland of Fano.
  • Battle of Pavia: The Roman army pursues the Alamanni in Lombardy. Aurelian closes the passes in the Alps and encircles the invaders near Pavia. The Alamanni are destroyed and Aurelian receives the title Germanicus Maximus.
• Following Aurelian's execution of Felicissimus, the financial minister of the state treasury, on the charge of corruption, the mint workers of the city of Rome, with senatorial support, lead an uprising against Aurelian. In bitter street-fighting on the Caelian Hill the rebels are defeated. The revolt is followed by a purge of Aurelian's senatorial opponents, including Urbanus.
• Around this time, generals loyal to Aurelian defeat the usurpers Septimius in Dalmatia and Domitian II in southern Gaul. The Iuthungian invasion may have encouraged the spate of revolts.
• Aurelian begins construction of a new defensive wall to protect Rome. The Aurelian Walls, 19 kilometers (12 mi), enclose the city with fortifications.
• Perhaps around this time, Aurelian increases Rome's daily bread ration to nearly 1.5 pounds and adds pig fat to the list of foods distributed free to the populace.
• Aurelian defeats a Gothic raid into the Balkans and then invades the Gothic homeland. Here he defeats the Goths again, killing one of their leaders, Cannabas, who may be Cniva, the Goth who had won the battle of Abritus, at which Emperor Decius was killed.
• Aurelian withdraws Rome's administrative and military presence from Dacia (modern Romania), thereby rationalizing the Danube frontier and freeing resources for the forthcoming campaign against Zenobia.

Europe

• Victorinus, Emperor of the Gallic Empire, is assassinated by one of his officers, Attitianus, reportedly for reasons of personal revenge. He is succeeded by Tetricus I, who is elevated with the help of Victorinus' mother Victoria.

Near East

• Zenobia invades Asia Minor and seizes control of Cilicia and Galatia before being stalled in Bithynia.
• Shapur I of the Sasanian Empire dies, and his successor, his son Hormizd I, leads an army against nomads in Sogdiana, perhaps taking command of a war that had begun under his father. (Note: Some scholars date Shapur's death to 270 or 272)

By place

Roman Empire

• Emperor Aurelian launches a two-pronged invasion of the Palmyrene Empire, sending his commander Marcus Aurelius Probus to restore Roman rule in Egypt while he marches into Asia Minor.
• As part of a strategy of clemency, Aurelian spares Tyana after capturing the city. This strategy encourages units under Zenobia to defect to Aurelian.
• Battle of Immae: Aurelian defeats the Palmyrene heavy cavalry (clibanarii) near Antioch. Queen Zenobia flees under cover of darkness to Emesa (Syria).
• Aurelian supports the bishops of Italy in deposing the bishop of Antioch, Paul of Samosata, who had been a supporter of Zenobia. This is the first recorded instance of an imperial intervention in an ecclesiastical dispute.
• Battle of Emesa: Aurelian decisively defeats the Palmyrene army.
• Aurelian besieges Palmyra. Zenobia attempts to escape to Persia but is captured on the Euphrates. Palmyra surrenders soon after.
• Following a series of trials held in Emesa, Cassius Longinus and other advisors of Zenobia are executed for conspiring against Aurelian.

Religion

• Dometius succeeds Titus as Patriarch of Constantinople.

Roman Empire

• Battle of Châlons: The Emperor Aurelian invades Gaul to campaign against the Gallic Empire (Gaul and Britain). In the Catalaunian Plains, the Romano-Gallic Emperor Tetricus I surrenders to Aurelian and leaves his army without an emperor. The Gallic army is then crushed by Aurelian in a major battle. With the conquests of the Palmyrene Empire and the Gallic Empire, the Roman Empire is united again. However, the heavy losses incurred by the Gallic forces compromises the Rhine frontier.
• Rome greets Aurelian as Restitutor Orbis ("Restorer of the World") and accords him a magnificent triumph (victory procession), which is graced by his captives Zenobia, Tetricus I, and his son Tetricus II.
• Aurelian reforms the Roman currency, replacing the denarius with a new version of the antoninianus that has a slightly improved silver-to-copper ratio. This overhaul of the currency system causes hyper-inflation.
• Germanic tribes take advantage of the destroyed Roman forces of the Rhine to raid Gaul.
• December 25 – Aurelian has the Temple of the Sun dedicated to Sol Invictus, on the third day after the solstice and day of rebirth of the sun. This religion, which is in essence monotheistic, becomes the state religion of Rome.

Africa

Religion

• March 2 – Mani, a sage of Persia, dies at Gundeshapur after 30 years of preaching his "heresy" at the court of the late Sassanian King Shapur I and on long journeys to Khorasan, India and China. He is executed or allowed to die in prison, and claims to be a prophet of God. Mani combines Zoroastrian dualism with Christian theology, and his disciples gain wide support for Manichaeism, despite opposition from Roman Emperors.
• December 30 – Pope Felix I dies in Rome after a 5-year reign.

Transportation

• Japanese shipwrights build a 100-foot oar-powered vessel for Emperor Ōjin. The Japanese will not use sails for another seven centuries.

Roman Empire

• Emperor Aurelian puts down unrest in Gaul, and defeats Germanic incursions into Gaul and Raetia (these problems had been caused by Aurelian's defeat and overthrow of the Gallic Empire).
• The Goths begin to raid Thrace and Asia Minor. Aurelian begins a campaign against the Goths in Thrace.
• Aurelian is assassinated near Byzantium (Turkey). Aurelian had developed a reputation for punishing corruption with severity, and his secretary Eros was under suspicion. As a result, Eros, fearing for his life, had forged a list of high-ranking officers marked for execution. In this way, the secretary tricked the officers into assassinating Aurelian, and they then fled into Asia Minor to avoid the wrath of the soldiers. Unusually for the period, the imperial field army defers to the Senate to choose a successor.
• September 25 – Marcus Claudius Tacitus is proclaimed Emperor by the Senate; his half brother Marcus Annius Florianus becomes praetorian prefect.
• Tacitus marches into Asia Minor to fight the Goths and track down the faction responsible for assassinating Aurelian.

• Tacitus' cousin Maximinus administers Syria in a harsh manner, and is assassinated by local men of power, who are joined in the conspiracy by the faction responsible for having assassinated Aurelian in the previous year.
• Tacitus dies in Tyana, Cappadocia. He either dies of illness, or is murdered by the faction responsible for having assassinated Aurelian and Maximinus.
• Florianus becomes Roman Emperor with the support of the Senate, but a general in the east, Marcus Aurelius Probus, usurps power against him. Florianus breaks off his campaign against the Goths and marches east from the Bosporus with support from the Roman legions in Britain, Gaul, Spain and Italy.
• Florianus holds power for some weeks and fights indecisively against Probus in Cilicia, but his soldiers, many of whom are from the colder Rhine and Danube frontiers, suffer from heat and disease. He is overthrown and then assassinated by his own troops near Tarsus (Turkey), in collusion with Probus. Probus, age 44, is proclaimed new Emperor of Rome.
• Probus returns the aurelianianus to the tariffing of Aurelian.
• Probus invites the faction responsible for the murders of Aurelian and Tacitus to a banquet, only to massacre them. He then arrests a surviving conspirator and has him burned alive.
