Kashf-e hijab

Reza Shah's wife Tadj ol-Molouk, and their daughters Shams and Ashraf, 8 January 1936, famously participating in a public ceremony without hijab for the first time.

On 8 January 1936, Reza Shah of Iran issued a decree known as Kashf-e hijab (also Romanized as Kashf-e hijāb and Kashf-e hejāb, Persian: کشف حجاب, lit. 'Unveiling') banning all Islamic veils (including hijab and chador), an edict that was swiftly and forcefully implemented. The government also banned many types of male traditional clothing.

The ban was enforced for a period of five years (1936–1941); after this, women were free to dress as they wished for forty years until the Iranian Revolution of 1979, when the reverse ban against unveiling was introduced. One of the enduring legacies of Reza Shah is turning dress into an integral problem of Iranian politics.
