Today is the one hundredth anniversary of the assassination of Archduke Franz Ferdinand and his wife Sophie, Duchess of Hohenberg, in Sarajevo, then a provincial capital of the Austro-Hungarian empire. The assassination, the act of a Serbian nationalist named Gavrilo Princip, is regarded as the spark that touched off World War I. To mark the anniversary, many newspapers, magazine, and websites have prepared special collections of materials, including contemporary news stories, historical documents, and scholarly retrospectives. Here are a links to three of the best of these collections:
The Great War: This New York Times feature includes front pages of the New York Herald (the precursor of the International Herald Tribune and today's International New York Times) from key points in the war, and eight articles (perhaps with more to come) on the legacy of the war reported from Ypres, Chateau-Thierry, Kiel, Sarajevo, and elsewhere.
First World War 100 Years On: The Guardian collects a large quantity of its reporting on topics related to the war in this section of its website. Even better (and somewhat more manageable), however, is a series entitled The First World War that ranges from "The Road to War" to "The Aftermath" with collected reporting--old and new--on each topic.
World War One: The BBC provides timelines, maps, study guides, news stories, and much more in this collection of links.
