WWI Timeline: A Brief History

World War I began on July 28, 1914, when Austria-Hungary declared war on Serbia after the assassination of Archduke Franz Ferdinand. Russia and Germany soon joined the conflict, followed by Britain, France, and Italy. On April 6, 1917, the US declared war on Germany, and 2.8 million men were drafted to fight.
Over the course of the next eighteen months, more sixty million troops worldwide and 4 million US troops were involved. By the end of the Great War on November 11, 1918, the violence across Europe resulted in an estimated thirty-seven million casualties and more than sixteen million deaths (including both civilians and military personnel).
