World War I began 100 years ago, on 28 July 1914. The initial trigger, the assassination of Archduke Franz Ferdinand of Austria, produced something of a "domino effect," where European powers, bound by pre-existing international alliances, chose sides and fell rather obviously into a catastrophic war. It started as a European war, pitting Allied powers against Central powers. But, soon enough, it became international, involving a long list of countries from Africa, North and South America, Asia, and Australasia. The trench warfare that became such an important part of World War I ensured that the battle lines moved ever so slowly, at least until the final stages of the war. That grinding quality gets captured remarkably well by EmperorTigerstar's latest YouTube video, "World War I: Every Day," which shows "the changing front lines of World War I every day from Austria-Hungary's declaration of war to the armistice of November 11, 1918." It also includes the changing front lines in Africa and the Pacific. (A legend, below, will help you sort out the various different players.) When you're done watching "World War I: Every Day" (above), you'll perhaps want to spend time with EmperorTigerstar's previous video, "World War II in Europe: Every Day," which documents an even bloodier war unfolding at a dramatic pace.
