The term 'Arab Royalty' can be summarized by the 4-letter word 'EMIR'. An EMIR is a title of high office used in a number of Arab countries, and is roughly equivalent to a prince or a governor. It is derived from the Arabic word 'amir', which means commander or leader. Historically, Emirs have been responsible for leading armies, administering justice, and managing the affairs of their respective regions. In modern times, they are often seen as figureheads of their respective nations, and may hold ceremonial roles in government.
