When Franz Ferdinand, the heir to the Austro-Hungarian throne, was assassinated in June, 1914, by a radical Serbian nationalist, the delicate peace that had survived in Europe for nearly a century since Napoleon was broken. Austria-Hungary declared war on Serbia, Russia came to their ally Serbia’s aid. Germany, led by Fredrick Wilhelm II, in turn backed the Austro-Hungarian army and invaded France by going through Belgium, a neutral country, drawing France and Great Britain into the war. On the western front between German-occupied land and France, things moved very slowly and both sides turned to trench warfare. Under these circumstances the German military issued occupational coinage under the direction of Helmuth von Moltke. This raises the question; what is military occupational coinage?
