Just to clarify, Cindy, in most cases men don't require women to wear hijabs, women choose to wear them (though yes, there obviously are situations in which it is forced).
Modesty is an Islamic virtue, and it is said that if one is not modest, then they also are not Muslim. So most Muslim women wear hijabs of their own free will in order to show their devotion to God and His will. That's why it's important to conservative Muslim women: they believe they are not Muslim without it.
The Qur'an tells them to wear one in the presence of all men who are not fathers, brothers or spouses.
