From wikipedia's History of Rape
Since the 1970s many changes have occurred in the perception of sexual assault due in large part to the feminist movement and its public characterization of rape as a crime of power and control rather than purely of sex. In some countries the women's liberation movement of the 1970s created the first rape crisis centers. This movement was led by the National Organization for Women (NOW). One of the first two rape crisis centers, the D.C. Rape Crisis Center (), opened in 1972. It was created to promote sensitivity and understanding of rape and its effects on the victim.
Marital rape first became a crime in the United States in the state of South Dakota in 1975. In 1993, North Carolina became the last state to outlaw marital rape.  The marital rape exemption was abolished in England and Wales in 1991 by the House of Lords, in its judicial capacity, in the case of R v R  1 AC 599 (more details).
In the 1980s, date or acquaintance rape first gained acknowledgment. An important part of the history of rape is the foundation of RAINN, which runs the national sexual assault hotline and is the leading organizer of rape crisis awareness as well as a research resource for the media. This is a national organization rather than regional and is regarded as an authority for statistics and other research. Rape crisis centers were created to serve survivors of all forms of sexual violence during any phase of their healing process. Rape crisis centers and other community based service providers continue to grow and serve their communities by providing direct services and prevention programming.
On September 2, 1998 the United Nations International Criminal Tribunal for Rwanda delivered a precedent-setting verdict that made sexual violence a war crime. This was followed in November 1998 by the decision of the International Criminal Tribunal for the former Yugoslavia that acts of rape may constitute torture under international humanitarian law.
Current topics being debated are the marginalized victims of rape — domestic violence and rape victims, marital rape victims, male rape victims of both male and female rapists, female-female rape victims, parental-rape incest victims, and child sexual abuse victims. Other emerging issues are the concept of victim blame and its causes, male rape survivors, male-male rape, female sexual aggression, new theories of rape and gender, date rape drugs and their effects as well as the psychological effects of rape trauma syndrome.
