The countries that were fighting most desperately in the First World War threw huge chunks of their national economies into the struggle in a search for victory.
Some statistics (very brief—I promise!). The money value of all the goods and services that a country produces is called the Gross Domestic Product (GDP). Peacetime governments skim off some of the GDP to spend on benefits for its citizens, such as roads, education and defence. As the war continued, though, some governments gobbled up larger shares of the GDP to spend on the war effort.
In 1913, the year before war broke out, the governments of France and Germany spent about 10 percent of their GDP. By 1916 government spending was closer to 50 percent—half the economy—mostly on the war effort.
These images from Germany and France, published in Scientific American this week 100 years ago, on March 4, 1916, show some of the extreme disruption to the economy (and social order) in these two countries that was caused by the ongoing world war.
