Goldsworthy Lowes Dickinson

Dickinson was deeply distressed by Britain's involvement in the First World War. Within a fortnight of the war's breaking out, he drew up the idea of a League of Nations, and his subsequent writings helped to shape public opinion towards the creation of the League.
Within the field of international relations, Dickinson is prominent for popularizing conceptions of the international system as being an international "anarchy." In contrast to many of his contemporaries who attributed the causes of war to national and imperial expansion or to population growth, Dickinson argued that war was rooted in fear and suspicion caused by anarchy and arms races.
