This entertaining and informative timeline from the National WWI Museum and Memorial will be a favorite with educators teaching the history of the 20th century. As a supplement to lesson plans and activities outlining the major developments of the war, the timeline brings events by integrating text, photos, drawings, maps, and videos. For instance, a quote by Kaiser Wilhelm II, "The sword is being forced into my hand," is followed by a 45-second video outlining the first months of the war, with Germany and Turkey forming alliances and the U.S. declaring neutrality. Though the figures and photos from the timeline offer a continual stream of excellent information, a few entries stand out, such as the 20,000 British troops that died in one day during the Battle of the Somme, or the ten suffragists who were arrested outside the White House on August 28, 1917.
