Elizabeth Angela Marguerite Bowes Lyon, the youngest daughter of the Earl of Strathmore, was born on 4 August 1900. It might reasonably have been expected that she would lead a life of ease and privilege but few could have imagined the profound effect she would have on Britain and its people. Her life spanned the whole of the twentieth century and this official biography tells not only her story but, through it, that of the country she loved so devotedly. Drawing on her private correspondence and other unpublished material from the Royal Archives, William Shawcross vividly reveals the witty girl who endeared herself to soldiers convalescing at Glamis in the First World War; the assured young Duchess of York; the Queen, at last feeling able to look the East End in the face at the height of the Blitz; and, the Queen Mother, representing the nation at home and abroad throughout her widowhood. It is the definitive portrait of a remarkable woman.
