Princess Diana's life was as dramatic as it was short-lived. When alive she brought joy to many; her death led to mass, hysterical mourning. She would have turned sixty in July this year. Diana's life and achievements are celebrated in three parts, and the zeitgeist and socio-cultural changes are compared in parallel with each decade (the seventies, eighties and nineties). People who either knew Diana or saw their lives intersect in other ways speak, and outline a thorough analysis of Diana's life and influence on the twentieth century.
