Describe historical socio-political context of Look Back in Anger

The character of Colonel Redfern, Alison's father, represents the decline of and nostalgia for the British Empire. The Colonel had been stationed for many years in India, a symbol of Britain's imperial reach into the world. The Edwardian age which corresponded to Britain's height of power, had been the happiest of his life. His nostalgia is representative of the denial that Osborne sees in the psyche of the British people. The world has moved on into an American age, he argues, and the people of the nation cannot understand why they are no longer the world's greatest power.
