Fought from 1914 to 1918, World War I plunged the global great powers into a grim death struggle that left millions of people dead and reshaped the world's map. Through thoughtful narrative supported by fully documented quotes, this title begins with A Brief History of World War I and then examines these questions: How Did an Austrian Nobleman's Assassination Lead to the Outbreak of World War I? How Did the Russian Revolution Change the Course of World War I? How Did Germany's Naval Strategy Influence the US Decision to Enter the War? How Did US entry into the War Lead to an Allied Victory?
