Arminiya, also known as the
Ostikanate of Arminiya (,
Arminia vostikanut'yun),
Emirate of Armenia (,
imarat 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 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.
