Battle of Bagrevand

The battle resulted in a crushing Abbasid victory, with the death of the main Armenian leaders.

The Caliph sent 30,000 Khurasanis under Amir ibn Isma'il into the province, and at the Battle of Bagrevand on 25 April 775, the nakharar suffered a decisive defeat, losing their leaders, Smbat VII Bagratuni and Mushegh VI Mamikonian.

The defeat of the Armenian revolt eliminated the power of several of the nakharar houses, most notably the Mamikonian, Gnuni, Amatuni, Rshtuni, Saharuni, and Kamsarakan families, which survived "either as dependants of other families, or as exiles in Byzantium" (Whittow).

[5] The Abbasids followed their re-imposition of control over Armenia by a similar purge of the native Christian nobility in neighbouring Iberia in the 780s, as well as by a new settlement policy which saw increasing numbers of Arab Muslims settled in the Transcaucasus, with the effect that by the turn of the 9th century, the Arab element predominated in the towns and lowlands.

In the next century, Caucasian Albania was effectively Islamicized, while Iberia and much of Armenia came under the control of a series of Arab emirates.
