## Events

### By place

#### Byzantine Empire

- Spring – A Muslim supply fleet of 760 ships under Sufyan arrives from [Egypt](/source/Egypt) and [North Africa](/source/Ifriqiya), concealing itself along the [Asiatic](/source/Asia_Minor) shore. The [Byzantines](/source/Byzantine_Empire) learn of the fleet's location from defecting [Christian Egyptian](/source/Copts) sailors. Emperor [Leo III](/source/Leo_III_the_Isaurian) sends the [Byzantine navy](/source/Byzantine_navy) again; his [Greek fire](/source/Greek_fire) ships destroy the enemy vessels in the [Sea of Marmara](/source/Sea_of_Marmara) and seize their supplies on shore, denying the sieging army vital provisions.[1] On land the Byzantine troops ambush an advancing Arab army, and destroy it in the hills around [Sophon](/source/Sapanca), south of [Nicomedia](/source/Nicomedia) (modern [Turkey](/source/Turkey)).[2][3][4][5] The Arab besiegers are still suffering from [hunger](/source/Hunger) and pestilence.

- [August 15](/source/August_15) – [Siege of Constantinople](/source/Siege_of_Constantinople_(717%E2%80%93718)): A [Bulgar](/source/First_Bulgarian_Empire) relief force attacks the [siege lines](/source/Investment_(military)) at [Constantinople](/source/Constantinople), on the west side of the [Bosporus](/source/Bosphorus). Contemporary [chroniclers](/source/Chronicle) report that at least 22,000–32,000 Arabs are killed during the Bulgarian attacks. Caliph [Umar II](/source/Umar_II) is forced to lift the [siege](/source/Siege) after 13 months; the Muslim army attempts to withdraw back through [Anatolia](/source/Anatolia), while the rest escapes by sea in the remaining vessels. The Arab fleet suffers further casualties to [storms](/source/Storm), and an [eruption](/source/Types_of_volcanic_eruptions) of the [volcano](/source/Volcano) of [Thera](/source/Santorini).[6] According to Arab sources 150,000 Muslims perish during the campaign.[7]

#### Western Europe

- [Battle of Soissons](/source/Battle_of_Soissons_(718)): King [Chilperic II](/source/Chilperic_II) of [Neustria](/source/Neustria) and his mayor of the palace [Ragenfrid](/source/Ragenfrid), allied with [Eudes](/source/Odo_the_Great), independent [duke of Aquitaine](/source/Duke_of_Aquitaine), march on [Soissons](/source/Soissons) in [Picardy](/source/Picardy) (northern France) but an army of [Frankish](/source/Francia) veterans under [Charles Martel](/source/Charles_Martel) defeat the Neustrian allies, who sue for peace. Chilperic flees to the land south of the River [Loire](/source/Loire) and Ragenfrid escapes to [Angers](/source/Angers). Charles diplomatically chooses not to execute the enemy leaders, and becomes undisputed *[dux Francorum](/source/Duke_of_the_Franks)*, ending the Frankish [civil war](/source/Civil_war).

- Summer – [Battle of Covadonga](/source/Battle_of_Covadonga): [Pelagius (Don Pelayo)](/source/Pelagius_of_Asturias) is proclaimed king (*[caudillo](/source/Caudillo)*), and defeats the [Umayyad](/source/Umayyad_Caliphate) forces under [Munuza](/source/Munuza), provincial governor of [Asturias](/source/Asturias), at [Picos de Europa](/source/Picos_de_Europa) (near [Covadonga](/source/Covadonga)). This marks the beginning of the *[Reconquista](/source/Reconquista)*, the Christian reconquest of the [Iberian Peninsula](/source/Iberian_Peninsula). He founds the [Kingdom of Asturias](/source/Kingdom_of_Asturias), and establishes a military base at [Cangas de Onís](/source/Cangas_de_On%C3%ADs) (northwest of Spain)[8] (or 722).

- King [Liutprand](/source/Liutprand%2C_King_of_the_Lombards) of the [Lombards](/source/Lombards) builds a close [alliance](/source/Military_alliance) with Charles Martel, and attacks the [Bavarian](/source/Bavaria) castles on the [River Adige](/source/Adige), maintaining strategic control of the Alpine [passes](/source/Mountain_pass) in the Italian [Alps](/source/Alps) (approximate date).

#### Britain

- King [Coenred of Northumbria](/source/Coenred_of_Northumbria) dies after a 2-year reign. The throne is seized by [Osric](/source/Osric_of_Northumbria), probably a younger brother, or half-brother, of the late king [Osred I](/source/Osred_I_of_Northumbria).

- Former queen [Cuthburh](/source/Cuthburh) of [Northumbria](/source/Northumbria), abbess of [Wimborne](/source/Wimborne_Minster_(church)), dies at her [abbey](/source/Abbey) and is buried there (approximate date).
