Events
By place
Byzantine Empire
September 15 – Battle of the Orontes: Fatimid forces, under Turkish general Manjutakin (also the governor of Damascus), besiege Apamea (modern Syria). Emperor Basil II sends a Byzantine expeditionary army, led by Dux Michael Bourtzes, to relieve the city in alliance with the Hamdanid Dynasty. Manjutakin defeats the Hamdanids with his forces and attacks the Byzantine force in the rear. The Byzantine army panics and flees, losing some 5,000 men in the process.
Europe
June 23 – Viking Age: Danish Viking raiders, (probably) under King Sweyn Forkbeard, plunder the city of Stade (Lower Saxony). Count Lothair Udo I is captured and killed, during the battle with the pirates.
September – King Otto III, now 14 years old, receives the regalia to rule the Kingdom of Germany at an assembly of the Imperial Diet in Solingen. Otto appoints Heribert of Cologne as chancellor of Italy.
England
A Danish Viking fleet, under Olaf Tryggvason, sails up the Thames Estuary, and besieges London. King Æthelred II (the Unready) pays Olaf 16,000 lbs of silver (Danegeld).
