This is a look into the events that laid the foundation for Australia in the 21st Century. Between 1919 and 1939 Australia turned from a rural backwater of the British Empire to a South East Asian nation. Award-winning journalist and author Chris Masters investigates the tumultuous 1920s and 30s and tells the story of parents, grandparents and great-grandparents who survived crisis after crisis and laid the groundwork for the nation we know today. In Australian mythology nationhood was forged in the slaughter of Gallipoli in 1915. But in The Years That Made Us, Chris Masters introduces a very different proposition. Far from bringing the nation together, the First World War tore the country apart and threatened to destroy the Federation dream. The Great Depression wrecked a struggling recovery and just when light appeared on the horizon the gates of hell reopened with the Second World War. The 21 years between the First and Second World Wars saw the world change faster than at any other time in history. The eruption of Communism and Fascism and the Great Depression were the big picture backdrops to extraordinary changes in culture and technology. The changes brought about in the vast desert continent were unique. In a personal journey that takes in big-picture history and his own family's story, Chris explores the idea that Australia's response to the tumultuous 21 years was unlike that of any other country.
