Book excerpt: In this book, Professor East discusses the vital relationship between history and geographical conditions. Drawing examples from ancient times up to the present, he demonstrates that a study of history must include consideration of the physical conditions under which an event occurs, and that "the particular characteristics of this setting serve not only to localise but also to influence part at least of the action." Topographical position, climate, distribution of water and minerals, the placement of routes and towns, and ease or difficulty of movement between districts and countries are among the factors which the historian must take into account.
