What caused the first world war?

The centenary of August 1914 is still almost a year away, but the tsunami of first-world-war books has already begun. The government tells us that 1914 must be commemorated, not celebrated, and ministers worry about British triumphalism upsetting the Germans. But the debate about Germany’s responsibility for the outbreak of war in 1914 won’t go away. Historians are divided into those who blame Germany — John Rohl, Max Hastings — and those who point the finger at someone else, such as Serbia (Christopher Clarke) or Russia (Sean McMeekin) or even Britain (Niall Ferguson). The blame game is of course conceptually flawed. The international system in 1914 was seriously dysfunctional. The alternative to searching for scapegoats is to examine the system. Why was it that political solutions no longer worked, so that conflicts could only be resolved by war? That is the question at the heart of Margaret MacMillan’s important new study.
