Ayatollah (UK: /ˌaɪəˈtɒlə/, also US: /ˌaɪəˈtoʊlə/; Arabic: اية الله, romanized: ʾāyatu llāh; Persian: آیتالله, romanized: âyatollâh [ɒːjjætˌolˈlɒːh]) is an honorific title for high-ranking Twelver Shia clergy. In Iran, it came into widespread usage in the 20th century.[1][2]
Originally used as a title bestowed by popular/clerical acclaim for a small number of the most distinguished marja' at-taqlid mujtahid, it suffered from "inflation" following the 1979 Iranian Revolution when it came to be used for "any established mujtahid".[3] By 2015 it was further expanded to include any student who had passed their Mujtahid final exam,[4] leading to "thousands" of Ayatollahs.[5]
The title is not used by the Sunni community of Iran,[1] nor by Shias in Lebanon, Pakistan, or India.[1] In Iraq, the title is not unknown, but is only used for clerics of Iranian origin.[1]
In the Western world – especially after the Iranian Revolution – it was associated with Ruhollah Khomeini, who was so well known as to often be referred to as "The Ayatollah".
