This year marks the 100th anniversary of the beginning of World War I which engulfed the globe from 1914 to 1919. It has been estimated that 10 million died and another 20 million were wounded in the conflict. Austria-Hungary declared war on Serbia on July 28, 1914 in response to the assassination of Archduke Franz Ferdinand, heir to the Austro-Hungarian Empire, on June 29. The "domino effect" of alliance obligations that ensued let to the inevitability of a global conflict, with Serbian ally Russia first declaring war on Austria-Hungary, and then Germany declaring war on Russia. Battles also took place in the Middle East. The United States eventually entered the war in 1917.
