eugene debs, a socialist who was put in prison for protesting u.s. involvement in wwi, ran for president from prion and received almost 1 million votes. this was also the first u.s. election in which women in all 48 states could vote.

picher, oklahoma produced most of wwi's bullets, thanks to its lead and zinc mine. 100 years later, the local river is still so polluted with arsenic that anyone who swims in it suffers chemical burns.

the trenches used by the british during wwi were primarily dug by 90,000 chinese laborers.

during christmas of 1914, during 'the great war', british and german soldiers declared a truce, exchanged presents and food, and had a soccer match. germany won 3 to 2. the following day, they went back to butchering each other.

toward the end of wwi, an amendment was proposed in the united states that would have allowed all voters to decide whether or not to go to war. anyone who voted yes would have had to volunteer for service.
