On 31 July 1914 the ILP’s Keir Hardie and Arthur Henderson signed an ‘Appeal to the British Working Class’ on behalf of the British section of the International Socialist Bureau, which called for them to ‘act promptly and vigorously in the interests of peace’.
‘There is no time to lose,’ they said. ‘Men and women of Britain, you have now an unexampled opportunity of showing your power, rendering a magnificent service to humanity and to the world. Proclaim that for you the days of plunder and butchery have gone by. Send messages of peace and fraternity to your fellows who have less liberty than you.’
