The twentieth century of the Common Era began on January 1, 1901 and ended on December 31, 2000, according to the Gregorian calendar.[1][2] It was marked by new models of scientific understanding, unprecedented scopes of warfare, new modes of communication that would operate at nearly instant speeds, and new forms of art and entertainment. Population growth was also unprecedented,[3] as the century started with around 1.6 billion people, and ended with around 6.2 billion.[4]
