Year 271 (CCLXXI) was a common year starting on Sunday (link will display the full calendar) of the Julian calendar. At the time, it was known as the Year of the Consulship of Aurelianus and Bassus (or, less frequently, year 1024 Ab urbe condita). The denomination 271 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.
- Emperor Aurelian pushes the Vandals back from Pannonia and forces them to withdraw over the Danube. He withdraws the Roman army from Dacia (modern Romania) and settles its inhabitants in Moesia. (Note: This may have lasted until 272. Both years are mentioned by various sources.)
- Battle of Placentia: The Juthungi invade Italy and sack the city of Piacenza. A Roman army (15,000 men) under Emperor Aurelian is ambushed and defeated.
- Battle of Fano: The Juthungi move towards a defenceless Ancient Rome. Aurelian rallies his men and defeats the Germanic tribes on the Metauro River, just inland of Fano.
- Battle of Pavia: The Roman army pursuit the Alamanni in Lombardy. Aurelian closed the passes in the Alps and encircled the invaders near Pavia. The Alamanni are destroyed and Aurelian received the title Germanicus Maximus.
- Felicissimus, financial minister of the state treasury, leads an uprising of mint workers against Aurelian. He is defeated and killed on the Caelian Hill.
- Aurelian begins construction of a new defensive wall to protect Rome. The Aurelian Walls, 19 kilometers (12 mi), enclose the city with fortifications.
- Victorinus, Emperor of the Gallic Empire, is assassinated by Attitianus, reportedly for reasons of personal revenge. Domitianus presumably serves as Emperor for a few days before being replaced by Tetricus I.
- Zenobia proclaims herself to be Empress, and breaks all relations with the Roman Empire.
- Zenobia gives her son Vaballathus the title of Augustus.
