"I was invited by the organizers of the United Nations Symposium on Femicide in Vienna, Austria, to conclude this one-day international policy-oriented meeting by proposing what I believed to be the best strategies to advance the global struggle against femicide.  I was also asked to describe the major challenges that I had personally encountered in my efforts to raise public awareness about femicides after I had introduced this term at the International Tribunal on Crimes Against Women in 1976 -- nearly four decades ago (Russell and Van de Ven, 1976). Because we speakers had to confine ourselves to about ten minutes for our presentations, I relish this opportunity to be able to provide some highlights of other speakers' contributions, as well as the vital document titled "The Vienna Declaration" that had to be finalized by the conclusion of the Symposium.  I also decided to revisit what has become the controversial issue of the definitions of femicide, femicidio, feminicide and feminicidio. ..."
