Exactly one hundred years ago, on 28 July 1914, socialist representatives from across Europe gathered in Brussels. Austria-Hungary had declared war on Serbia. Much of the rest of Europe was expected to join in.
French socialist leader Jean Jaures stood with his arm around the co-chair of the German Social Democrats, Hugo Haase. They insisted that whatever governments and capitalists might do, working-class people must refuse to fight each other. Thousands of people marched against war in cities throughout Europe.
