Provides a portrayal of the history of the 20th century from the expansion of colonial empires at the turn of the century to the decline of the Soviet empire and the unification of Germany. The book details the changing fortunes of nations since 1900, catalogues the events and consequences of wars and summarizes the more subtle social and economic shifts that have underpinned recent history. The book is divided into six chronological sections. Each section starts with an essay to introduce the historical themes of the period and concludes with a detailed chronology of events. In between are double page spreads on particular topics - the cause of World War I, the Russian Revolution, the Spanish Civil War, Nazi Europe, decolonization in Africa, communist China, the world in 1990 - in which maps and text provide a easily assimilated introduction to the rapid changes of this century.
