The 'Alawi dynasty – also rendered in English as Alaouite, 'Alawid, or Alawite – is the current Moroccan royal family and reigning dynasty. They are an Arab Sharifian dynasty and claim descent from the Islamic prophet Muhammad through his grandson, Hasan ibn Ali. Their ancestors originally migrated to the Tafilalt region, in present-day Morocco, from Yanbu on the coast of the Hejaz in the 12th or 13th century.
