Rape, unlawful sexual activity, most often involving sexual intercourse, against the will of the victim through force or the threat of force or with an individual who is incapable of giving legal consent because of minor status, mental illness, mental deficiency, intoxication, unconsciousness, or deception. In many jurisdictions, the crime of rape has been subsumed under that of sexual assault. Rape was long considered to be caused by unbridled sexual desire, but it is now understood as a pathological assertion of power over a victim. By that definition, rape is "the penetration, no matter how slight, of the vagina or anus with any body part or object, or oral penetration by a sex organ of another person, without the consent of the victim."
