The 'open door' into Antarctica: an explanation of the Hughes doctrine

This article seeks to explain the doctrine concerning sovereignty in Antarctica articulated by Charles E. Hughes, a former US Secretary of State, and to account for its persistence in underpinning US Antarctic policy. The doctrine was part of the New Imperialism - the surge of colonial expansion and spheres of influence that occurred in the late 19th and early 20th centuries. US imperialism sought to establish an "open door' international order to exploit America's growing economic power; the Hughes doctrine extended this policy into Antarctica, preserving US access to all the region by denying recognition of claims by other countries. -Author
