The demonstrations during Muharram brought millions onto the streets.
Here is a cluster of religiously-inspired demonstrators, all wearing a kafan (shroud of the dead), signifying their own readiness to be martyred.
The slogan reads:
“God is great, our movement is like Hussein, our leader is Khomeini”
الله اکبر٬ نهضت ما حسینی٬ رهبر ما خمینی
There are plenty of images of Khomeini.
And women marched also, sometimes with a cordon of men encircling them for protection from the thugs (chomagh-ba-dast) of the Shah’s regime
