This subreddit was formed in late 2013 to document World War I, day by day as it developed. It covers social, political, military and cultural developments in combatant countries and noncombatants alike. Its particular emphasis is on pointing out the most striking similarities and differences from the problems humanity faces today.
Rules
All submissions must deal with things that happened exactly 100 years ago, using the Gregorian calendar. August 5, 2014 is all about August 5, 1914.
