Throughout the 20th century and long before, hundreds of determined British women defied the social conventions of their day in order to seek adventure and influence on the world stage. Some became travellers and explorers; others business-owners or buyers; others still devoted their lives to worthy international causes, from anti-slavery and women's suffrage to the League of Nations and world peace. Yet until 1946, no British woman could officially represent her nation abroad. It was only after decades of campaigning and the heroic labours performed by women during the Second World War that diplomatic careers were finally opened to both sexes. This book tells this story of personal and professional struggle against the dramatic backdrop of war, super-power rivalry and global transformation over the last century and a half.
