|History of Armenia|
Arminiya, also known as the Ostikanate of Arminiya (Armenian: Արմինիա ոստիկանություն, Arminia vostikanut'yun), Emirate of Armenia (Arabic: إمارة آلارمينيا, imārah al-Arminiya), was a political and geographic designation given by the Muslim Arabs to the lands of medieval Armenia, Caucasian Iberia, and Caucasian Albania following their conquest of these regions in the seventh 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.
The first Arab expedition reached Armenia in 639 AD. Dvin was captured and pillaged during this raid on 6 October 640. A second invasion took place in 642–643 and a third in 650, which captured some land north of Lake Van. According to bishop Sebeos, in January 642, the Arabs took the city of Tovin (Duin) by storm, slaughtered twelve thousand of its inhabitants and carried away thirty-five thousand into slavery.
Armenia however remained under Byzantine suzerainty until 653/654, when Theodore Rshtuni voluntarily conceded Arab suzerainty and was recognized as autonomous prince of Armenia in return. According to this agreement, Armenia was recognized as an autonomous state subject to an annual tribute and a contribution of fifteen thousand troops to the Arab army. With Arab aid, Rhstuni repelled Byzantine attacks, and Arab troops even captured Theodosiopolis in 655, and cemented their control of the country by taking Rhstuni to Damascus and appointing his rival Hamazasp Mamikonian in his stead.
In 661 however, the victor of the Muslim civil war Mu'awiyah ordered the Armenian princes to re-submit to his authority and pay tribute. In order to avoid another war, the princes complied. The Arab policy of demanding that the tribute be paid in money had an effect on Armenian economy and society. Coins were struck in Dvin. The Armenians were forced to produce a surplus of food and manufactured goods for sale. A strong urban life was developed in Caucasia as the economy revived.
Establishment of direct Muslim control
For most of the second half of the 7th century, Arab presence and control in Armenia was minimal. Armenia was considered conquered land by the Arabs, but enjoyed de facto autonomy, regulated by the treaty signed between Rhstuni and Mu'awiyah in 654. The Armenian princes were submitted to—relatively low—taxation and the obligation to provide soldiers when requested, for which the princes were to be paid an annual subsidy of 100,000 dirhams. In exchange, no Arab garrison or official was installed in Armenian lands, and Arab assistance was even promised in the event of Byzantine attack. The situation changed in the reign of the caliph Abd al-Malik (r. 685–705). Beginning in 700, the Caliph's brother and governor of Adharbayjan (modern Iranian Azerbaijan), Muhammad ibn Marwan, subdued the country in a series of campaigns. Although the Armenians rebelled in 703 and received Byzantine aid, Muhammad ibn Marwan defeated them and sealed the failure of the revolt by executing the rebel princes in 705. Armenia, along with the principalities of Caucasian Albania (modern Azerbaijan) and Caucasian Iberia (modern Georgia) was grouped into one vast province called al-Arminiya (آلارمينيا), with its capital at Dvin (Arabic Dabil), which was rebuilt by the Arabs and served as the seat of the governor (ostikan) and of an Arab garrison. For much of the remaining Umayyad period, Arminiya was usually grouped together with Adharbayjan and the Jazira into a single super-province.
Armenia was governed by an emir or wali headquartered at Dvin, whose role however was limited to defence and the collection of taxes: the country was largely run by the local princes, the nakharar. The province was formally established . The Emirate of Armenia (al-Arminiya) was divided into four regions: Arminiya I (Caucasian Albania), Arminiya II (Caucasian Iberia), Arminiya III (the area around Aras River), Arminiya IV (Taron). The local nobility was headed, as in Sasanian times, by a prince (ishkhan), a title which in the 9th century, beginning probably with Bagrat II Bagratuni, evolved into the title of "prince of princes" or "presiding prince" (ishkhan ishkhanats′). Acting as the head of the other princes, the ishkhan was answerable to the Arab governor, being responsible for the collection of the taxes owed to the caliphal government and the raising of military forces when requested.
A census and survey of Arminiya was undertaken ca. 725, followed by a significant increase in taxation so as to finance the Caliphate's increasing military needs in the various fronts. The Armenians participated with troops in the hard-fought campaigns of the Arab–Khazar wars in the 720s and 730s. As a result, in 732, governor Marwan ibn Muhammad (the future Caliph Marwan II) named Ashot III Bagratuni as the presiding prince of Armenia, an act which essentially re-confirmed the country's autonomy within the Caliphate.
Abbasid period until 884
With the establishment of the Abbasid Caliphate after the Abbasid Revolution, a period of repression was inaugurated: Caliph al-Saffar subdued the Armenian rebellion of 747–750 with great brutality, and his successor al-Mansur revoked the privileges and subsidies of the nakharar and imposed harsh taxation, leading to the outbreak of another major rebellion in 774. The revolt was suppressed in the Battle of Bagrevand in April 775. The failure of the rebellion saw the near-extinction, reduction to insignificance or exile to Byzantium of some of the most prominent nakharar families, most importantly the Mamikonian. In its aftermath, the Caliphate tightened its grip on the Transcaucasian provinces: the nobility of neighbouring Iberia was also decimated in the 780s, and a process of settlement with Arab tribes began which by the middle of the 9th century led to the Islamization of Caucasian Albania, while Iberia and much of lowland Armenia came under the control of a series of Arab emirates. At the same time, the power vacuum left by the destruction of so many nakharar clans was filled by two other great families, the Artsruni in the south (Vaspurakan) and the Bagratuni in the north.
Despite several insurrections, the Emirate of Armenia lasted until 884, when the Bagratuni Ashot I, who had managed to win control over most of its area, declared himself "King of the Armenians". He received recognition by Caliph Al-Mu'tamid of the Abbasid dynasty in 885 and Byzantine Emperor Basil I of the Macedonian dynasty in 886.
Ashot was swiftly able to expand his power. Through family links with the two next most important princely families, the Artsruni and the Siwnis, and through a cautious policy towards the Abbasids and the Arab emirates of Armenia, by the 860s he had succeeded in becoming in fact, if not yet in name, an autonomous king.
