Women should be married from the age of nine and only educated to the age of 15 according to a manifesto from the Islamic State in Iraq and Syria posted to a jihadist forum.

The document was first posted by the media wing of the Khanssaa Brigade, an ISIS women’s group and was translated into English by the British think tank the Quilliam Foundation. It lambasts the “Western program for women” and lays out the expectations for the “sedentary” role of women under ISIS, which controls swathes of Syria and Iraq.

Haraqs Rafiq, the managing director of Quilliam, said in a statement that the manifesto provides a starkly different perspective on female life under ISIS than that projected by some of the hundreds of Western women who have traveled to the region.

“It allows us to look past the propaganda banded about on social media by Western supporters of ISIS, enabling us to get into the mind-set of the hundreds, perhaps thousands, of women who willingly join its ranks,” he said.

The manifesto, which Quilliam says was likely intended to attract women from the conservative Gulf region, discusses a female education focused on religion and says the “purpose of her existence is the Divine duty of motherhood.”
