Editing 726 (section)

=== By place ===

==== Byzantine Empire ====
* Emperor [[Leo III the Isaurian|Leo III]] issues a [[Byzantine Iconoclasm|series of edicts]] banning the veneration of images (726–729), and launching the [[iconoclasm|iconoclastic]] controversies.<ref>Treadgold. ''History of the Byzantine State'', pp. 350, 352–353</ref> Most of the [[clergy]] – particularly in [[Italy]] and [[Greece]] – are opposed to these [[edict]]s with uncompromising hostility, and in the western parts of the [[Byzantine Empire]] the people refuse to obey his religious reforms.  
* [[Arab–Byzantine wars#Raids under the last Umayyads and the rise of Iconoclasm|Arab–Byzantine War]]: Muslim forces under [[Maslama ibn Abd al-Malik]] resume their expedition against [[Anatolia]] (modern [[Turkey]]). In a large-scale raid they [[Looting|plunder]] the fortress city of [[Kayseri|Caesarea]].<ref>Treadgold (1997), p. 349</ref>

==== Europe ====
* [[Islamic invasion of Gaul|Umayyad conquest of Gaul]]: Muslim raiders under [[Abdul Rahman Al Ghafiqi|Abdul Rahman al-Ghafiqi]], current governor of [[Septimania]], devastate [[Avignon]], [[Viviers, Ardèche|Viviers]], [[Valence, Drôme|Valence]], [[Vienne, Isère|Vienne]] and [[Lyon]] (approximate date).
* [[Marcello Tegalliano]] dies after a 9-year reign. 
* Uprising in Venice against Byzantium: The cause of mass unrest is the [[Iconoclasm|iconoclastic]] decrees of Emperor Leo III. A few days later, political demands are put forward for wide autonomy within the Byzantine Empire and the right to appoint the ruler of the region (Doge). The rebels elect [[Orso Ipato]] the Doge of [[Republic of Venice|Venice]]. Desiring to preserve the proceeds of the treasury from the second most important port of the Byzantine Empire, and not having the resources to cope with a well-fortified and armed region, Byzantium agrees with all the requirements put forward. Orso Ipato is recognised by Leo III, who gives him the title ''[[hypatos]]''. The Venetian fleet, led by Orso Ipato, frees Ravenna from the Lombards and restores the power of the Byzantine governor there.
* Seismic activity in the [[Mediterranean Sea]]: The [[volcanic island]] of [[Santorini|Thera]] erupts, while the city of [[Jerash]] (in present-day [[Jordan]]) suffers a major [[earthquake]].

==== Britain ====
* King [[Ine of Wessex]] resigns his crown, and travels on a [[pilgrimage]] to [[Rome]]. He is succeeded by his brother-in-law (and probably distant cousin) [[Æthelheard of Wessex|Æthelheard]].<ref>Yorke. ''Kings and Kingdoms'', p. 147</ref>
* [[Dúngal mac Selbaig]] is deposed as king of [[Dál Riata]] ([[Scotland]]). He is succeeded by [[Eochaid mac Echdach]] (a son of former king [[Eochaid mac Domangairt]]).

==== Asia ====
* The first annual [[Sumo]] tournament in [[Japan]] is held by [[Emperor Shōmu]] (approximate date).
