6The assassination of Archduke Franz Ferdinand on June 28, 1914 by a Serbian nationalist has set off a crisis in Europe.

France supports Russia but also needs Britain on its side. Can war be avoided one more time? Europe on the Brink plunges students into the July Crisis as representatives of the European powers.
