Two provinces of NW Iran, Eastern Azerbaijan (capital Tabriz), population (1986) 4,114,000, and Western Azerbaijan (capital Orumiyeh), population 1,972,000. Azeris in Iran as in the USSR, are Muslim (Shi'ite) ethnic Turks, descendants of followers of the Khans from the Mongol Empire. There are about 5 million in Azerbaijan, and 3 million distributed in the rest of the country, where they form a strong middle class. In 1946, with Soviet backing, they briefly established their own republic. Denied autonomy under the Shah, they rose 1979-80 against the supremacy of Ayatollah Khomeini and were forcibly repressed, although a degree of autonomy was promised. Since 1988 there has been a growth in Azer nationalism, spearheaded by the local Azerbaijani Popular Front and fanned by the dispute with neighbouring Christian Armenia over Nagorno-Karabakh and Nakhichevan. This dispute, which reawakened centuries-old enmities, flared into a war from Dec 1989 which prompted Azer calls for secession from the USSR and led in Jan 1990 to the despatch of Soviet troops to Baku in an attempt to restore order.
