When was the spousal rape law passed?
According to the National Center for Victims of Crime, in an article titled "Spousal Rape Laws: 20 Years Later":
"Until the late 1970's, most states did not consider spousal rape a crime. Typically, spouses were exempted from the sexual assault laws. For example, until 1993 North Carolina law stated that "a person may not be prosecuted under this article if the victim is the person's legal spouse at the time of the commission of the alleged rape or sexual offense unless the parties are living separate and apart." These laws are traceable to a pronouncement by Michael Hale, who was Chief Justice in England in the 17th century, that a husband cannot be guilty of rape of his wife "for by their mutual matrimonial consent and contract the wife hath given up herself in this kind unto the husband which she cannot retract." In the late 1970's, feminists began efforts to change these laws. Currently, rape of a spouse is a crime in all 50 states and the District of Columbia."
