By place
Byzantine Empire
- August 20 – Battle of Achelous: A Byzantine expeditionary force (62,000 men) under General Leo Phokas (the Elder) is routed by the Bulgarians at the Achelous River near the fortress of Anchialos (modern Pomorie) on the Black Sea coast. Phokas flees to Mesembria (modern Nesebar) and escapes by boarding a ship. Tsar Simeon I (the Great) becomes de facto ruler of the whole Balkan Peninsula, except the well-protected Byzantine capital of Constantinople and the Peloponnese.[1]
- Fall – Battle of Katasyrtai: The Bulgarian army under Simeon I marches southwards to Constantinople. Leo Phokas, who survived at Anchelous, gathers the last Byzantine troops to intercept the Bulgarians before they reach the capital. The two armies meet near the village of Katasyrtai, just outside Constantinople. After a surprise night attack, the Byzantines are completely routed from the battlefield.[2]
Europe
- Bulgarian–Serbian War: Simeon I sends a Bulgarian expeditionary force under Theodore Sigritsa and Marmais to Serbia. The two persuade Petar Gojniković, a Serbian prince who formed an anti-Bulgarian coalition, to meet for a peace agreement. They seize him and send the rebellious prince to the Bulgarian capital of Preslav, where he dies in prison. Simeon replaces Petar with Pavle Branović, a grandson of prince Mutimir, who lives in Preslav. Serbia becomes a puppet state until 921.[3]
- The Hungarians, after attacking Swabia, sack and burn Basel (modern Switzerland). They invade Lorraine in Lotharingia, destroying Verdun and Moyenmoutier, and many monasteries in Alsace. Duke Arnulf I (the Bad) with Hungarian military aid, reconquers his land from King Conrad I of the East Frankish Kingdom. After this event, Bavaria and Swabia agree to pay tribute to the Hungarians.
- Battle of Confey: The Norse Vikings under Sigtrygg Caech defeat and kill King Augaire mac Ailella of Leinster in battle. Sigtrygg re-captures Dublin and establishes himself as king, while his kinsman Ragnall ua Ímair returns to England to become King of Northumbria.

- Summer – Lady Æthelflæd of Mercia cements an alliance with King Constantine II of Scotland against Norse York. She captures the fortress at Derby (belonging to the Five Boroughs of the Danelaw), while her brother, King Edward the Elder, takes Towcester.[4] Æthelflæd's armies also ravage Brycheiniog (Wales) in revenge for killing the Mercian abbot Ecbryht (see 916).
