One of my old projects I had a cinematic idea for.
Turban is a complicated subject, according to my researches and some documents Turbn is an Aryan tradition, and not Islamic. Iranic people(Aryans) had 2 different cultures: Northern Iranians that we call them Scythians/Sarmatians, they are the ancestors of Slavic people, etc.. they used the sharp helmet because they were warriors.
On the other side are the Southern Iranians (Bactrians), they used Turban because of their Zoroastrian roots. When later Arabs attacked Iran, they absorbed Turban to their culture like other things. Facts like this show that Turban is not an Islamic tradition.
