Events

August 14 – Emperor Tiberius II Constantine, age 47, dies (possibly from deliberately poisoned food) at Constantinople, after a 4-year reign during which Thrace and Greece have been inundated by the Slavs. He is succeeded by his son-in-law Maurice, former notary who has commanded the Byzantine army in the war against the Persian Empire.
Autumn – Maurice elevates John Mystacon to magister militum per Orientem.^[1] He sends a Byzantine expeditionary force to Arzanene (Armenia), where they fight a pitched battle at the river Nymphius (Batman River).^[2]^[3]

Siege of Sirmium: The Avars, under their ruler (khagan) Bayan I, aided by Slavic auxiliary troops, capture the city of Sirmium after almost a 3-year siege. Bayan establishes a new base of operations within the Byzantine Empire, from which he plunders the Balkan Peninsula.
Gundoald, illegitimate son of Clotaire I, arrives with the financial support of Constantinople in southern Gaul. He claims as usurper king the cities Poitiers and Toulouse, part of the Frankish Kingdom (approximate date).
The Visigoths under King Liuvigild capture the city of Mérida (western central Spain), which is under the political control of its popular bishop Masona. He is arrested and exiled for 3 years.

A Persian army under Tamkhosrau crosses the Euphrates River and attacks the city of Constantina (modern Turkey), but he is defeated by the Byzantines and killed.

Spring – Emperor Xuan, age 52, dies after a 13-year reign and is succeeded by his incompetent son Houzhu, who becomes the new ruler of the Chen dynasty.
Emperor Wen of the Sui dynasty orders the building of a new capital, which he calls Daxing (Great Prosperity), on a site southeast of Chang'an (modern Xi'an).
