Abū al-ʿAbbās Aḥmad ibn Muḥammad ibn Kathīr al-Farghānī also known as Alfraganus in the West, was an astronomer in the Abbasid court in Baghdad, and one of the most famous astronomers in the 9th century. Al-Farghani composed several works on astronomy and astronomical equipment that were widely distributed in Arabic and Latin and were influential to many scientists. His best known work, Kitāb fī Jawāmiʿ ʿIlm al-Nujūmi, was an extensive summary of Ptolemy's Almagest containing revised and more accurate experimental data. Christopher Columbus used Al Farghani’s calculations for his voyages to America. In addition to making substantial contributions to astronomy, al-Farghani also worked as an engineer, supervising construction projects on rivers in Cairo, Egypt. The lunar crater Alfraganus is named after him.

The Shaddadids were a Kurdish Sunni Muslim dynasty. who ruled in various parts of Armenia and Arran from 951 to 1199 AD. They were established in Dvin. Through their long tenure in Armenia, they often intermarried with the Bagratuni royal family of Armenia.
Dvin was a large commercial city and the capital of early medieval Armenia. It was situated north of the previous ancient capital of Armenia, the city of Artaxata, along the banks of the Metsamor River, 35 km to the south of modern Yerevan. The site of the ancient city is currently not much more than a large hill located between modern Hnaberd and Verin Dvin, Armenia. Systematic excavations at Dvin that have proceeded since 1937 have produced an abundance of materials, which have shed light into the Armenian culture of the 5th to the 13th centuries.

The Sajid dynasty, was an Iranian Muslim dynasty that ruled from 889/890 until 929. The Sajids ruled Azerbaijan and parts of Armenia first from Maragha and Barda and then from Ardabil. The Sajids originated from the Central Asian province of Ushrusana and were of Iranian (Sogdian) descent. Muhammad ibn Abi'l-Saj Diwdad the son of Diwdad, the first Sajid ruler of Azerbaijan, was appointed as its ruler in 889 or 890. Muhammad's father Abu'l-Saj Devdad had fought under the Ushrusanan prince Afshin Khaydar during the latter's final campaign against the rebel Babak Khorramdin in Azerbaijan, and later served the caliphs. Toward the end of the 9th century, as the central authority of the Abbasid Caliphate weakened, Muhammad was able to form a virtually independent state. Much of the Sajids' energies were spent in attempting to take control of neighboring Armenia. The dynasty ended with the death of Abu'l-Musafir al-Fath in 929.

Arminiya, also known as the Ostikanate of Arminiya or the Emirate of Armenia, was a political and geographic designation given by the Muslim Arabs to the lands of Greater Armenia, Caucasian Iberia, and Caucasian Albania, following their conquest of these regions in the 7th century. Though the caliphs initially permitted an Armenian prince to represent the province of Arminiya in exchange for tribute and the Armenians' loyalty during times of war, Caliph Abd al-Malik ibn Marwan introduced direct Arab rule of the region, headed by an ostikan with his capital in Dvin. According to the historian Stephen H. Rapp in the third edition of the Encyclopaedia of Islam:
Early Arabs followed Sāsānian, Parthian Arsacid, and ultimately Achaemenid practice by organising most of southern Caucasia into a large regional zone called Armīniya.
Abu'l-Aswar or Abu'l-Asvar Shavur ibn Fadl ibn Muhammad ibn Shaddad was a member of the Shaddadid dynasty. Between 1049 and 1067 he was the eighth Shaddadid ruler of Arran from Ganja. Prior to that, he ruled the city of Dvin from 1022 as an autonomous lord. A capable warrior, and a wise and cunning ruler, Abu'l-Aswar was engaged in several conflicts with most of his neighbours. During his rule over Dvin, he was mostly involved in the affairs of the Armenian principalities. He collaborated with the Byzantine Empire in its conquest of the last remnants of Bagratid Armenia in 1045, but when the Byzantines later turned on him, he survived three successive offensives that sought to take Ganja. In 1049, a revolt in Ganja overthrew his infant great-great-nephew, Anurshirvan. The rebels invited him to take up the family's emirate, and he moved from Dvin to Ganja. Under his rule, the Shaddadid dynasty reached its zenith. He undertook successful campaigns into Georgia and Shirvan, although the limits of Shaddadid power were exposed by his failure to take over the Emirate of Tiflis and by devastating raids by the Alans. At the same time, his reign witnessed the rapid rise of the Seljuk Empire and the extension of its control over the Transcaucasian principalities. Abu'l-Aswar became a Seljuk vassal in 1054/5. Although he gained control over the former Armenian capital of Ani through Seljuk patronage in 1065, this association also paved the way for the dynasty's decline after his death in November 1067.
The 856 Damghan earthquake or the 856 Qumis earthquake occurred on 22 December 856. The earthquake had an estimated magnitude of 7.9, and a maximum intensity of X (Extreme) on the Mercalli intensity scale. The meizoseismal area extended for about 350 kilometres (220 mi) along the southern edge of the eastern Alborz mountains of present-day Iran including parts of Tabaristan and Gorgan. The earthquake's epicenter is estimated to be close to the city of Damghan, which was then the capital of the Persian province of Qumis. It caused approximately 200,000 deaths and is listed by the USGS as the sixth deadliest earthquake in recorded history. This death toll has been debated.
al-Bidāya wa-l-Nihāya, sometimes also known as the Tārīkh Ibn Kathīr, is a work on Islamic history by the Sunni Muslim scholar Ibn Kathir.
Ardabil is a city in northwestern Iran, and the capital of Ardabil Province.
The 893 Dvin earthquake occurred on 28 December at around midnight. It had a magnitude of approximately 6 and a maximum intensity of approximately IX (Violent) on the Mercalli intensity scale. It destroyed the city of Dvin in Armenia, causing approximately 30,000 casualties. The similarity of the Arabic name for Dvin, 'Dabil' to Ardabil in northwestern Iran, has caused confusion in written records, such that the 893 Ardabil earthquake appears in several catalogues, although it is generally regarded as a false event. It was also recorded as an event during the classical period of India in several early catalogues at an unspecified capital.
Ibrahim I ibn Marzuban I was the Sallarid ruler of Dvin (957–979) and later Azerbaijan. He was the son and successor of Marzuban ibn Muhammad.
