U.S. groups campaign to oppose abortion, 1987-1991
Led by the nonviolent action organization Operation Rescue, thousands of mostly working and middle class Christians from Evangelical and Catholic denominations waged a massive sit-in campaign between 1987 and 1990 to promote pro-life values. The campaign culminated in a nationally organized multi-year wave of nonviolent blockades of medical clinics. Legal action by women’s organizations and new federal laws put a stop to the campaign.
