Events

Vladimir, ruler (khan) of the Bulgarian Empire, is dethroned by his father Boris I, with help from loyal boyars. He is blinded, and succeeded by his brother Simeon I, as prince of Bulgaria; the capital is moved from Pliska to Preslav. Simeon makes an alliance with the Pechenegs (or Patzinaks), a semi-nomad Turkic tribe from the Central Asian steppes.^[1]
An East Frankish expeditionary force under Zwentibold, the eldest son of King Arnulf of Carinthia, crosses the Alps into Friuli. He makes junction at Verona, with the army of the deposed king Berengar I, and proceeds to lay siege to Pavia. After a three-month campaign, Zwentibold receives orders to head back to Bavaria, in case of a Magyar intervention.
The 13-year-old Charles III (the Simple), the posthumous son of Louis the Stammerer, is crowned king of the West Frankish Kingdom at the Reims Cathedral—though he is not recognized as such by King Odo (or Eudes) until 898.^[2]
King Alfonso III repopulates the city of Zamora with Mozarabs (Iberian Christians who have lived under Moorish rule) from Toledo in Al-Andalus (modern Spain).
Galindo II Aznárez succeeds his father Aznar II Galíndez as count of Aragon (until 922).

Spring – A Viking army under Hastein moves to a fortified camp at Benfleet (Essex). The Danish camp is captured by the Saxons, while the army is out raiding. Hastein is forced to retreat to Shoebury.^[4]
Summer – Battle of Buttington: A combined Welsh and Mercian army under Lord Æthelred besieges a Viking camp at Buttington in Wales. The Danes escape with heavy losses, and take their families to safety in East Anglia.^[5]
Autumn – Danish Vikings under Hastein take the city of Chester, after a rapid march from East Anglia. Alfred the Great destroys the food supplies, forcing them to move into Wales.^[6]
Asser, bishop of Sherborne, writes his Life of King Alfred in Wessex. He studies for 6 months each year in Alfred's household.

The Jazira provinces of Diyar Rabi'a and Diyar Mudar are returned to the Abbasid Caliphate. Muslim forces recover direct control of Mosul (modern Iraq) from the Shayban.^[7]

March 23 – 893 Ardabil earthquake. Several earthquake catalogues and historical sources describe this earthquake as a destructive earthquake that struck the city of Ardabil, Iran. The magnitude is unknown, but the death toll was reported to be very large. The USGS, in their "List of Earthquakes with 50,000 or More Deaths", give an estimate that 150,000 were killed, which would make it the ninth deadliest earthquake in history.^[8]
