The World War of 1914-18 - The Great War, as contemporaries called it -- was the first man-made catastrophe of the 20th century. Historians can easily identify the literal "smoking gun" that set the War in motion: a revolver used by a Serbian nationalist to assassinate Archduke Franz Ferdinand (heir apparent to the Austro-Hungarian throne) in Sarajevo on June 28, 1914. But scholars are still debating the underlying causes. Was it the desire for greater empire, wealth and territory? A massive arms race? The series of treaties which ensured that once one power went to war, all of Europe would quickly follow? Was it social turmoil and changing artistic sensibilities brought about by the Industrial Revolution? Or was it simply a miscalculation by rulers and generals in power? The answer provided in "The Great War and The Shaping of the 20th Century" is that all of these volatile elements combined to set off a gigantic explosion we now know as World War I.
