Ed-Dowleh is a suffix used as part of titles for members of royalty who were in governing positions during the Qajar dynastyinIran (Persia). Some of the children of Abbas Mirza who were governors also carried this title. It derives from the medieval Arabic title al-Dawla. The suffix translates literally into "of the government" but in actual usage is meant to refer to the shah who bestows the title of -dowleh.[1] Ed-Dowleh can also be translated as "of the Empire or State."[2]
An example of usage would be the brother of Mohammad Ali Shah Qajar, Salar ed-Dowleh (1881-1961). Some other examples using members of the Qajar royal family carrying the title include:
The title was largely lost after Reza Shah, the creator of the Pahlavi dynasty, who had Iranians pick family names. Many families with the ed-Dowleh suffix dropped the title while keeping the first segment of their title as their surnames.[1]
