Book excerpt: The post-First World War period was pivotal in global history, international relations and geopolitics. And no more than in South Asia. where for decades the 'Great Game' in geopolitical rivalry of the two greatest modern empires - Britain and Russia - had dominated international relations. But with the advent of Communism in Russia and growing nationalism and pan-Islamism in Afghanistan, Persia and India, Britian's imperial standing was under threat. Faced with these problems, some in the British government, such as Lord Curzon, the dominant imperialist in the British Foreign Office, fell back on what they knew - old patterns of rivalry and high-handedness that characterised the Great Game. Not all, however, agreed with Curzon, and with war in Afghanistan, civil unrest in India, and rising tensions in Persia, those who opposed this Great Game mindset advocated a new way forward for British foreign relations.
