ON THIS DAY · 23 JULY 1914
The ultimatum
23 Jul 1914 — Vienna hands Serbia a 48-hour ultimatum written to be refused. Serbia accepts nearly all of it; Austria-Hungary declares war anyway on the 28th, and shells Belgrade the next day.
THE MOMENT IN CONTEXT
Look at the map before anything moves: two armed blocs already drawn. Charcoal in the center — Germany and Austria-Hungary, allied since 1879; blue around the rim — France and Russia, allied since 1894, with Britain attached to both by “ententes” that promised consultation, not war. Europe had been at peace for forty-three years, and its general staffs had spent every one of them writing railway timetables for the war they expected. That is the trap: mobilization is not a threat, it is the first act of the war plan — Germany’s plan in particular begins with an attack on France through Belgium, whoever the crisis is actually about.
