Bertrand Russell 
Freedom and Organization [PDF ebook] 

Written by one of the twentieth century’s most significant thinkers, Freedom and Organization, is considered to be Bertrand Russell’s major work on political history. It traces the main causes of political change during a period of one hundred years, which he argues were predominantly influenced by three major elements — economic technique, political theory and certain significant individuals. In the witty, approachable style that has made Bertrand Russell’s works so revered, he explores in detail the major forces and events that shaped the nineteenth century.
