What were the events before World War I that triggered the war?
this is an extremely complicated question that nearly a century of historical research and a lifetime’s study of same here have not fully answered. we recommend study of the following : the rise of nationalism and its militarising effects on european youth of the late 19th and early 20th century; the arms race between european nations commencing in the 19th century; relations between germany and the austro-hungarian empire; un-official co-operation between english and french military authorities; the rapid rise of russia as an industrial and military power and its political instability; background to the 2 balkan wars just prior to ww1; the ” schlieffen ” plan; and so much more. we thoroughly recommend the book ” The Pity of War ” by Niall Ferguson for a very interesting analysis of many of these and other factors.
