 Because of efforts by anti-rape activists and RCCs on local, state, and federal levels, the 1970s and 80s saw many important legislative changes that greatly improved the situation for rape survivors.Among these achievements are the criminalization of marital rape, rendering a rape survivor's prior sexual history inadmissible as evidence in court (rape shield law), repealing the requirement for corroboration in rape cases, and eliminating the requirement that survivors must have physically resisted the attack in order to prosecute.Another important development was expanding the legal definition of rape to include forced oral and anal sex, penetration by a finger or object, and a number of other acts and situations.
