'Abdallah the Hero'; died in 740) was a Muslim Arab commander in the Arab–Byzantine Wars of the early 8th century, participating in several of the campaigns launched by the Umayyad Caliphate against the Byzantine Empire.
Historical facts about his life are sparse, but in Anatolia, a legendary tradition grew around him after his death, and he became a famous figure in Turkish epic literature as Battal Gazi.
[1] In reliable historical sources (the chroniclers al-Ya'qubi and al-Tabari), al-Battal first appears in 727, in one of the annual raids against Byzantine Asia Minor.
Al-Battal led the vanguard, with which he penetrated as far as the city of Gangra in Paphlagonia, which he captured and razed, before the army went on to unsuccessfully lay siege to Nicaea.
Al-Battal and Malik's force reached as far as Akroinon, but there they were confronted and defeated by the Byzantines under Emperor Leo III the Isaurian (r. 717–741) in person.
[1][7][8] Although his military career was "not particularly distinguished" according to Marius Canard, Abdallah al-Battal quickly became the subject of popular tales and his fame grew, so that by the 10th century he was well established as one of the heroic figures of the Arab–Byzantine Wars: al-Mas'udi (The Meadows of Gold, VIII, 74–75) ranks him among the "illustrious Muslims" whose portraits were displayed in Byzantine churches as a mark of respect.
[13] A cult developed around him as a saintly figure ("sayyid"), especially among the Alevi and Bektashi sects, and his supposed tomb at Seyitgazi became a major centre of pilgrimage until the early 20th century, drawing pilgrims from as far as Central Asia.
