Some would argue that the presence of women in the public sphere increased at a certain point through changes to dress and the increased use of the veil or hijab in some Muslim communities. The hijab or veil is seen by some researchers as an extension of the home and functions to protect women from the view of non-kin males. The domination of women through social conventions such as enforcing the use of the veil and the creation of guardians of women, and limits to movement within and outside of the home are evident in existing historical record.
