Events

By place

Europe

• May 27 – Simeon I, emperor (tsar) of the Bulgarian Empire, dies of heart failure in his palace at Preslav after a 34-year reign. He is survived by four sons and succeeded by his second son Peter I, who signs a peace treaty with the Byzantine Empire. The peace is confirmed by Peter's marrying Maria Lekapene (the daughter of Christopher Lekapenos, son and co-emperor of Romanos I). The treaty restores the borders to those established by several treaties (thus recognizing Bulgaria's possession of Macedonia).^[1]
• July 12 – King Æthelstan of Wessex claims his kingdom and receives the submission of High-Reeve Ealdred I of Bamburgh and probably also of Owain ap Dyfnwal, King of Strathclyde, at Eamont Bridge.
