Domestic Violence Awareness Month evolved from the first Day of Unity observed in October, 1981 by the National Coalition Against Domestic Violence. The intent was to connect battered women’s advocates across the nation who were working to end violence against women and their children. The Day of Unity soon became a special week when a range of activities were conducted at the local, state, and national levels.

These activities were as varied and diverse as the program sponsors but had common themes: mourning those who have died because of domestic violence, celebrating those who have survived, and connecting those who work to end violence.

In October 1987, the first Domestic Violence Awareness Month was observed. That same year the first national toll-free hotline was begun. In 1989 the first Domestic Violence Awareness Month Commemorative Legislation was passed by the U.S. Congress. Such legislation has passed every year since with NCADV providing key leadership in this effort.

In October 1994 NCADV, in conjunction with Ms. Magazine, created the "Remember My Name" project, a national registry to increase public awareness of domestic violence deaths. Since then, NCADV has been collecting information on women who have been killed by an intimate partner and produces a poster each October for Domestic Violence Awareness Month, listing the names of those documented in that year.

The Day of Unity is celebrated the first Monday in October. National Coalition Against Domestic Violence (NCADV) hopes that events in communities and regions across the fifty states will culminate in a powerful statement celebrating the strength of battered women and their children.
