William Lyon Mackenzie King has perhaps the most enduring legacy of any Canadian Prime Minister: his policies shaped Canadian politics, economics and international relations for much of the twentieth century. His influence remains hotly debated and controversial: this book is one of the first to counter the official hagiography of King promulgated by the Liberal Party. The Age of Mackenzie King offers a compelling alternative to the official history of the vital early years of Mackenzie King's career. It considers his role as a labour relations expert and official, the beginning of his close working relationship with powerful forces in the United States, notably the Rockefeller family, and his emergence as a leading Liberal politician. It traces the influences, alliances and experiences that provided the basis for Mackenzie King's highly sucessful vision of Liberal party poltics, a vision that had tremendous implications for Canadian development in the twentieth century. The Age of Mackenzie King is a groundbreaking study of one the most influential and enigmatic figures in Canadian history.
