This is a very interesting and informative video by Al-Arabiya news channel about the history of the Sudanese turban, or ‘Al 3imma’ as it is colloquially known in Sudan. The video explores the different ways different Sudanese men wear it, and why they chose to wear it that way.
This video is in Arabic and unfortunately does not have subtitles.
However, be sure to watch this silly video featuring two pals, a Sudanese and a Saudi, competing on who could put on their traditional headdress (3imma/shmagh) on faster. Hilarious!
