Greek fire provided a technilogical advantage and victory during the salvation of what city which is also the capital city of the Roman/Byzantine from two Arab sieges?
Greek fire Greek fire was an incendiary weapon used by the Eastern Roman (Byzantine) Empire that was first developed . The Byzantines typically used it in naval battles to great effect, as it could continue burning while floating on water. It provided a technological advantage and was responsible for many key Byzantine military victories, most notably the salvation of Constantinople from two Arab sieges, thus securing the Empire's survival.
List of Abbasid governors of Tarsus Tarsus is a city in Cilicia, a region in southeastern Asia Minor (modern Turkey). The city came under Roman control since 67 BC, and then passed on to the Byzantine Empire until the mid-7th century, when following the Muslim conquest of the Levant control was disputed with the nascent Caliphate. During the conflicts between the Byzantines and the Umayyads the city lay in the disputed no-man's-land between the two empires and changed hands frequently, becoming deserted and ruined in the process. In 778/9 the Abbasids undertook the first attempt to restore the city as a base of operations against Byzantium, but the work was apparently not completed. It was not until 787/8 that the city was rebuilt and resettled by Faraj ibn Sulaym on the orders of Caliph Harun al-Rashid (r. 786–809). 3,000 Khurasanis and 2,000 Syrians (a thousand each from Antioch and al-Massisa) were given houses and land in the new fortress city.
