Events

Emperor Maurice builds more fortifications along the Danube frontier, separating the Byzantine Empire from the realm of the Avars and Slavs (approximate date).
Comentiolus, Byzantine general (magister militum), assembles an army of 10,000 men at Anchialus (modern Bulgaria). He prepares an ambush for the Avars in the Haemus Mountains.^[1]

King Guntram sends envoys to Brittany, to stop the raiding on Frankish territory. He compels obedience from Waroch II and demands 1,000 solidus for looting Nantes.
King Reccared I renounces Arianism and adopts Catholicism.^[2] Many Visigothic nobles follow his example, but in Septimania (Southern Gaul) there are Arian uprisings.
November 28 – Treaty of Andelot: Guntram recognizes King Childebert II of Austrasia as heir. He signs a treaty with Queen Brunhilda at Andelot-Blancheville.
Winter – Childebert II appoints Uncelen as the Duke of Alemannia (approximate date).

Battle of Shigisan: The Soga clan, which has intermarried with the royal Yamato clan, fights the Mononobe and Nakatomi clans over influence in selecting a new successor for the Japanese throne, after Emperor Yōmei dies. The Soga favor importing Buddhism from the Asian mainland, described there as the religion of the most civilized. The Mononobe and Nakatomi hold that Buddhism would be an affront to the gods. The Soga win the civil war and Sushun, age 66, becomes the 32nd emperor of Japan.
Fall – The Liang dynasty ends: Emperor Wéndi of the Sui dynasty abolishes Western Liang and expands his territory into the lower valley of the Yangtze River. He sends his official Gao Jiong to the capital Jiangling, to pacify the citizens. The former emperor Xiao Jing Di becomes a vassal and is named the Duke of Liang.
Bagha Qaghan becomes the seventh ruler (khagan) of the Turkic Kaganate.

The filioque clause is first used in the Nicene Creed, against the Arians in Visigothic Spain (approximate date).
