The Muslim invasion of Anatolia and Armenia

Events

Byzantine Empire

  • Emperor Heraclius creates a buffer zone (or no man's land) in the heartland of Asia Minor. In the mountainous terrain of Anatolia, the Byzantine forces develop a system of defensive guerrilla warfare. The strategy is known as ‘shadowing warfare’, as it avoids battle with major Muslim invaders, and instead attacks raiding parties on their return when they are laden with booty, captured livestock or prisoners.[1]
  • July 4 Heraklonas, age 12, son of Heraclius, obtains (through the influence of his mother Martina) the title of Augustus. This brings him in rivalry with his elder half-brother Constantine.
  • Heraclius issues his Ekthesis, espousing the Monothelete doctrine (that there is only one will in Christ), and setting it forth as the official doctrine of the Eastern Orthodox Church. The Ekthesis is vigorously opposed, notably by Maximus the Confessor.

Britain

  • King Oswald and his Northumbrian army besiege and conquer Edinburgh (Scotland). His half-brother, Oswiu of Bernicia, marries Princess Rhiainfelt, heiress of North Rheged ("Old North"). Northumbria embraces North Rheged in a peaceful takeover, and Oswiu becomes a sub-king (approximate date).

Arabian Empire

  • January The Plague of Amwas breaks out.
  • Autumn The Arabian forces under Abu Ubaidah ibn al-Jarrah storm Caesarea Maritima, capital of Byzantine Palestine, and effect their final capture of Ascalon (modern Israel). Caliph Umar I stops the Muslim invasion, and appoints Abu Ubaidah governor of Syria.
  • Arab-Byzantine War: The invading Rashidun army under Khalid ibn al-Walid moves into Anatolia, conquering (without strong Byzantine resistance) the cities of Kahramanmaraş, Caesarea Cappadociae, Sebastia, and Malatya (west of the Taurus Mountains). Arab forces march into Armenia, where they capture the cities Edessa and Amida up to the Ararat plain.
  • Umar I dismisses Khalid ibn al-Walid after the conquest of Syria, owing to his ever-growing fame and influence. He wants the Muslims to know that victory comes from God, not his general.
  • Abu Musa al-Asha'ari, companion (sahabah) of Muhammad, establishes Hafar al-Batin, located in the northeastern region of the Arabian Peninsula. He orders the digging for new wells, along this desert route that Muslims travel from Iraq to Mecca for the Hajj (pilgrimage).

Asia

  • The Tibetan Empire, seeking an alliance through marriage with Tang dynasty China, launches an attack on Songzhou that is repelled by Chinese forces, but is followed by the marriage of the Chinese Princess Wencheng to Tibetan ruler Songtsän Gampo.
