1919 was another year that left an incredible mark on the globe, and particularly on the United States. In July, the United States Army sent a convoy across the continental U.S. to see whether or not it would be possible to cross all of North America by road. This particular effort took many months to complete and was woefully inefficient, but because of it, the U.S. Highway System would be born.
Even though we don't necessarily think about these early years of the 20th century as critical to human history today, all it takes is one cursory glance at some of the things that happened during 1918 to see that if anything, that may just be a bit of an understatement.
1917 was a year of many firsts. Jeannette Rankin officially became the first female member of the United States House of Representatives in March of that year, right around the time that Woodrow Wilson was sworn in for his second term as president. The Republic of China would later terminate all diplomatic relations with Germany, something that would act as the starting point for a lot of the conflict born in the coming decades.
