Ostikan

Ostikan (ոստիկան) was the title used by Armenians for the governors of the early Caliphates. In modern historiography, it is chiefly used for the caliphal governors of the province of Arminiya, which included Greater Armenia.

Early governors
These are reported as governors under the Caliphs Uthman (r. 644–656) and Ali (r. 656–661), as well as the early Umayyads:
 * Hudhayfa ibn al-Yaman
 * Al-Mughira ibn Shu'ba
 * Al-Qasim ibn Rabi'a ibn Umayya ibn Abi al-Salt al-Thaqafi
 * Habib ibn Maslama al-Fihri
 * Al-Ash'ath ibn Qays al-Kindi (ca. 657)
 * Al-Muhallab ibn Abi Sufra (ca. 686)

Emirs (Ostikans)
