Is wearing hijab mandatory for Iranian women?

On 8 March 1979, more than 100,000 women gathered on the streets of the Iranian capital to protest against the new Islamic government’s compulsory hijab ruling, which meant that women would henceforth be required to wear a headscarf when away from home. The protest was held on International Women’s Day, and the images show women from all walks of life �" nurses, students, mothers �" marching, smiling, arms raised in protest.
