The Huns starting to invade Europe
Roman Empire
- February – Julian, Roman Caesar, is proclaimed emperor by the Gallic legions in Lutetia (modern Paris), at the Thermes de Cluny. They refuse to support the eastern campaign against King Shapur II of Persia, and revolt.
- The Alamanni raid Raetia (Switzerland), but are pushed back behind the Rhine by Julian, into the Black Forest.
- King Shapur II continues his campaign against the Roman fortresses, capturing Singara, Bezabde and Nisibis.
- Emperor Constantius II and Julian exchange several letters, both hoping to avoid a civil war.
Europe
- The Huns invade Europe by the thousands, spreading terror as they take over territories held for generations by Alans, Heruls, Ostrogoths and Visigoths.
Science
- Theon of Alexandria, Greek mathematician, observes a solar eclipse (June 16) and a lunar eclipse (November 25). He gains some renown for his version of Euclid’s Elements and his commentaries on Ptolemy’s Almagest.
Agriculture
- Roman authorities in Britain export wheat to supply the legions on the Rhine; they have encouraged production of wheat for that purpose.
Religion
- Council of Constantinople (360): Emperor Constantius II requests a church council, at Constantinople; both the eastern and western bishops attend the meeting. Ulfilas also attends the council and endorses the resulting creed. After the council several homoiousian bishops are deposed or banished, including Macedonius I of Constantinople and Cyril of Jerusalem.
- At about this date, Ligugé Abbey in France is founded for the monastic Order of Saint Benedict by Martin of Tours, under dispensation from Bishop Hilary of Poitiers.
