Ed-Dowleh

Ed-Dowleh is a suffix used as part of titles for members of royalty who were in governing positions during the Qajar dynasty in Iran (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. Ed-Dowleh can also be translated as "of the Empire or State."

Usage
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:

Decline
