The Byzantine Empire (717) with its themes

Leo III (left) and his son Constantine V

Events

By place

Byzantine Empire

• March 25 – Emperor Theodosios III is deposed after a reign of 1 year and 10 months. He is succeeded by the 32-year-old Leo III the Isaurian, a general (strategos) of the Anatolic Theme (modern Turkey). Theodosios and his son enter the clergy, and probably becomes bishop of Ephesus. Leo brings an end to the Twenty Years' Anarchy in the Byzantine Empire, which marks the beginning of the so-called Isaurian Dynasty.^[1][2][3]
• Arab–Byzantine War: Muslim general Maslama ibn Abd al-Malik leads his army of 80,000 men from Pergamum to Abydos, where he crosses the Hellespont. To prevent interference by the Bulgars, or by any Byzantine forces in Thrace, he sends part of his army to a covering position near Adrianople; with his main body, Maslama builds siege lines to blockade Constantinople, which is protected by the massive Theodosian Walls.
• August 15 – Siege of Constantinople: Maslama begins a combined land and sea effort to capture Constantinople. The capital controls the Bosporus, access between the Mediterranean and Black Sea, and is defended by a garrison of roughly 25,000 men. Leo III orders the granaries be restocked and siege engines installed. The Arab besiegers are suffering immense losses due to disease, and from attrition of siege warfare.
• September 1 – A Muslim armada consisting of 1,800 ships commanded by admiral Suleiman, sails into the Sea of Marmara and drops anchor below the sea walls of Constantinople to supply their forces ashore. Leo III orders the Byzantine fleet with Greek fire to sally forth from their protected harbors, setting alight the thickly-packed Muslim ships. Many vessels burst into flames, while others collide with each other before sinking.^[4]
• Fall – Basil Onomagoulos, Byzantine official, declares himself rival emperor in Sicily after the news arrived that Constantinople is fallen to an Arab siege. Leo III dispatches a chartoularios named Paul with imperial instructions for the Byzantine army on the island. Basil is arrested and executed, his head is sent to Leo, while the other rebels are multilated and exiled.

Europe

• March 21 – Battle of Vincy: Charles Martel invades Neustria and defeats the forces of king Chilperic II at Vincy, near Cambrai. He pursues him and his mayor of the palace Ragenfrid to Paris, before turning back to deal with his stepmother Plectrude at Cologne to turn over half the wealth of his late father Pepin of Herstal. Charles allows both Plectrude and the young Theudoald to live, and obliges her to accept his sovereignty.
• Charles Martel consolidates his power and proclaims Clotaire IV king of Austrasia in opposition to Chilperic and deposes Rigobert, bishop of Reims, replacing him with Milo. He marched against Radbod, king (or duke) of the Frisians, and pushes him back into his territory (later part of the Netherlands). Charles sends the Saxons back over the Weser River and secures the Rhine border—in the name of Clotaire.
• Paolo Lucio Anafesto dies after a 20-year reign and is succeeded by Marcello Tegalliano as the second doge of the Republic of Venice.

Arabian Empire

• Caliph Sulayman ibn Abd al-Malik dies after a 2-year reign and is succeeded by his cousin Umar II. During his rule he grants tax exemption and tries to reorganize the Umayyad finances.
• A Muslim expedition under Al-Hurr ibn Abd al-Rahman al-Thaqafi cross the Pyrenees into Aquitanian territory, leading a small raiding party into Septimania (Southern France).

Asia

• December 24 – An earthquake shakes many places in northern Syria, and destroys the Old Church of Edessa.
• Hoshi Ryokan, the world's second-longest surviving hotel, is established in Japan (approximate date).
