["\nAbstract\nThe outbreak of the First World War is one of the great formative events of modern times. Yet during its centenary, there was surprisingly little attention to how uncertain entry into the war was in the English‐speaking world or how finely balanced the forces for and against intervention were. This article examines the role of appeals to honour in the decision for war. It begins by exploring the role of these appeals in convincing radical liberals to accept British intervention – something they had been successfully blocking just days earlier – before examining parallel appeals in the United States and Australia. It then considers why the language of honour was effective, and whether it still plays a role a century later, before concluding with some possible centennial lessons.\n", "Journal of Historical Sociology, Volume 33, Issue 2, Page 248-262, June 2020.
