The Valkyries began as the Kentucky Force[1] of the Women's Football League in 2006. They changed their identity to the Kentucky Knightmares in the off season but changed it again to the Valkyries prior to the 2007 season.[2] They were originally planning to be a member of the Women's Professional Football League for its final season of 2007,[3] but various complications led to them backing out before the season began.
