Twentieth century

"Twentieth Century, perhaps for the first time, allows us to understand the extraordinarily dynamic, and extraordinarily disturbing, century through which we all have lived. Roberts's work goes beyond simple narrative in distinguishing the major long-term changes that run beneath the flux of events to establish a true world history and not merely a story of the relations of powers and governments."--BOOK JACKET. "As Roberts shows, the fundamental changes of the twentieth century fall outside the framework that conventional international relations and its history employs. These changes include a worldwide increase in life expectancy, revolutionary strides in science and technology, and the radical reconfiguration of the global economy."--BOOK JACKET.
