Nikephoros I or Nicephorus I was Byzantine emperor from 802 to 811. Having served Empress Irene as genikos logothetēs, he subsequently ousted her from power and took the throne himself. In reference to his career before becoming Emperor, he is sometimes surnamed "the Logothete" and "Genikos" or "Genicus". Nikephoros pursued wars against the Arabs and Bulgarians, with mixed results; while invading Bulgaria he was defeated and killed at the Battle of Pliska.
Abu Ja'far Harun ibn Muhammad al-Mahdi or Harun ibn al-Mahdi, famously known as Harun al-Rashid was the fifth Abbasid caliph of the Abbasid Caliphate, reigning from September 786 until his death. His reign is traditionally regarded to be the beginning of the Islamic Golden Age. His epithet "al-Rashid" translates to "the Orthodox", "the Just", "the Upright", or "the Rightly-Guided".
Staurakios or Stauracius was Byzantine emperor from 26 July to 2 October 811. He was born in the early 790s, probably between 791 and 793, to Nikephoros I and an unknown woman. Nikephoros seized the throne of the Byzantine Empire from Empress Irene in 802, and elevated Staurakios to co-emperor on 25 December 803. On 20 December 807, a bride show was held by Nikephoros to select a wife for Staurakios, which resulted in his marriage to Theophano of Athens, a kinswoman of Irene. Little else is known of him until he came to take the throne upon the death of Nikephroros.
Michael of Synnada or Michael the Confessor was a metropolitan bishop of Synnada from 784/7 to 815. He represented Byzantium in diplomatic missions to Harun al-Rashid and Charlemagne. He was exiled by Emperor Leo V the Armenian because of his opposition to iconoclasm, and died on 23 May 826. He is honoured as a saint by the Eastern Orthodox and Roman Catholic churches, his feast day is May 23.
The Battle of Krasos was a battle in the Arab–Byzantine Wars that took place in August 804, between the Byzantines under Emperor Nikephoros I and an Abbasid army under Ibrahim ibn Jibril. Nikephoros' accession in 802 resulted in a resumption of warfare between Byzantium and the Abbasid Caliphate. In late summer 804, the Abbasids had invaded Byzantine Asia Minor for one of their customary raids, and Nikephoros set out to meet them. He was surprised, however, at Krasos and heavily defeated, barely escaping with his own life. A truce and prisoner exchange were afterwards arranged. Despite his defeat, and a massive Abbasid invasion the next year, Nikephoros persevered until troubles in the eastern provinces of the Caliphate forced the Abbasids to conclude a peace.
The Abbasid invasion of Asia Minor in 782 was one of the largest operations launched by the Abbasid Caliphate against the Byzantine Empire. The invasion was launched as a display of Abbasid military might in the aftermath of a series of Byzantine successes. Commanded by the Abbasid heir-apparent, the future Harun al-Rashid, the Abbasid army reached as far as Chrysopolis, across the Bosporus from the Byzantine capital, Constantinople, while secondary forces raided western Asia Minor and defeated the Byzantine forces there. As Harun did not intend to assault Constantinople and lacked ships to do so, he turned back.
The Abbasid invasion of Asia Minor in 806 was the largest of a long series of military operations launched by the Abbasid Caliphate against the Byzantine Empire. The expedition took place in southeastern and central Asia Minor, where the Abbasid and Byzantine empires shared a long land border.
Al-Qasim ibn Harun al-Rashid was an Abbasid prince, the third son of the Abbasid caliph Harun al-Rashid, and for a time third-in-line to the Abbasid throne.
Khuzayma ibn Khazim ibn Khuzayma al-Tamimi was a powerful grandee in the early Abbasid Caliphate. The son of the distinguished military leader Khazim ibn Khuzayma, he inherited a position of privilege and power, and served early on in high state offices. He was crucial in securing the accession of Harun al-Rashid in 786, and was an influential figure throughout his reign. During the civil war of 811–813 he sided with al-Amin, but finally defected to the camp of al-Amin's brother al-Ma'mun and played a decisive role in ending the year-long siege of Baghdad in a victory for al-Ma'mun's forces.
Ḥumayd ibn Ma'yūf al-Ḥajūrī was an Arab commander in Abbasid service in the early 9th century.
Sa'id ibn Salm al-Bahili was an Arab governor and military commander of the early Abbasid Caliphate.
Abu Sulaym Faraj al-Khadim al-Turki, sometimes erroneously called Faraj ibn Sulaym, was an Abbasid court eunuch and official.
