After the war, and as the Treaty of Versailles made so painfully clear, Germany and Austria-Hungary were held primarily responsible for starting the four-year conflict, one that resulted in the deaths of some 37 million people. It's an assessment that has changed very little since that time, and for good reason. But other major players were involved as well, each of them contributing to the start of the Great War — and escalating it into a global crisis — in their own way.
