Q: One historian of this period argues that we must ask the question "why not" rather than "why" in seeking to understand it, citing the role of "uncontrollable forces" in it. That man, Paul Schroeder, has analogized this period to a "Galloping Gertie". Arno Mayer cites the rise of radical groups in characterizing this period as "counterrevolutionary" and arguing for "The Primacy of Domestic", rather than international, "politics". This period is characterized as the beginning of the "Age of Catastrophe" in The Age of Extremes; in that work Eric Hobsbawm argues that the beginning of this period was also the beginning of the > "Short Twentieth Century". Factors traditionally cited as contributing to the beginning of this conflict include rigid war plans, militarism, alliances, imperialism, and nationalism. For 10 points, identify this conflict, which was sparked by Gavrilo Princip's assassination of Franz Ferdinand.
