The First World War defined the twentieth century. In its wake, millions died. In its wake, millions lay wounded or displaced. World War I unleashed violence and tragedy on a scale never before seen during the course of human history.

One hundred years on, the debate on the origins of the Great War remains unresolved. The July Crisis of 1914, as the thirty eight days between the assassinations at Sarajevo and the British declaration of war on Germany are known, was not inevitable. In the summer of 1914 diplomacy failed. As a result, Europe fell into somber apocalypse.

We will follow the march to war together, day by day. My aim is to share with you a few documents every week that trace the development of the 1914 July Crisis as it happened. Together, we will understand how peace was shattered. Together, we will understand how Europe went to war in the summer of 1914.

  4. Thanks for liking my review of Weitz’s book on Weimar Germany. If you dig a bit deeper into that blog, you’ll also find reviews of some works relating to 1914, including Clarke’s ‘The Sleepwalkers’.

    You might also find this posting from a year ago on my other blog of interest: http://robertday154.wordpress.com/2014/02/10/nineteen-fourteen/

    I am only an amateur historian, so feel free to disagree or debate any of my observations!

  5. Excellent site! I normally do Environmental History, but I’ve been reading a lot about this era lately. Lots of good material here, which I’m looking forward to digging into!

      Thank you for your comment. Unfortunately, I have not yet watched the BBC’s “37 Days”, but I have heard good things about it.

      You’re welcome, Peter! You have a very good blog.

  9. Thank you for liking my blog posts about my book Searching for Hugo. I appreciate that you also use letters and other documents to show the development of the war. I’ve found that letters impart a better understanding of the people involved and help bridge the span of time. Very glad to see your blog.

    War is something illogical – especially the developments after it has started. You will never understand this madness. So: Don’t be surprised if it comes again if you invest trillions and trillions into war, military, nuclear weapons, education for warfare and scientific research.

  17. Incredible work!

    My mother’s side is interesting as her father was Ukranian and seems to have migrated all over Europe, to escape problems & wars happening during early part of his life but my mother ended up over here.
