On 7th May 1979 the Iranian newspapers announced a new law had been passed stating all women must wear a headscarf in public.
The following day, more than 100,000 women took to the streets to protest.
Photographer Hengameh Golestan was there to capture it. “They were demanding the freedom of choice,” Golestan says.
“It wasn’t a protest against religion or beliefs, in fact many religious women joined the protest, this was strictly about women’s rights, it was all about having the option.”
Despite these demonstrations, the law remained, and newspapers declined to publish Golestan’s pictures.
