In December 1936 at the height of the Abdication Crisis Cosmo Gordon Lang Archbishop of Canterbury held the fate of the British monarchy in his hands. Together with the Prime Minister Stanley Baldwin he helped to manoeuvre Edward VIII from the throne & to replace him with the kings brother the Duke of York who was to become George VI. It was a move which would have far-reaching consequences for the course of British history. The period 1928-1942 saw some of the greatest political & social upheavals in modern British history & Lang was at the centre of these. As Archbishop of Canterbury he led the Church of England through this tumultuous period & was a pivotal influence in political & religious decision-making. Although Lang has often been seen as a fairly unsuccessful archbishop who was resistant to change Robert Beaken shows that he was in fact an effective leader of the Church at a difficult time. He also proved to be a sensitive leader during wartime opposing any demonization of the enemy & showing compassion to conscientious objectors. Drawing on previously unseen material Beaken tells the story of a fascinating yet complicated man who was Britains first modern Archbishop of Canterbury.
