In A History of Rugby, written by Penny Hopkins and narrated by Chris Stafford, we explore the origins of the game, why women were first playing in secret, Miss Emily Valentine's role in the game and chronicle the sport's development from World War II through to the establishment of Rugby Sevens, the introduction of international competitions and participating nations through to the advent of professional status for women and the prospects for the 2017 World Cup.
