The story of the hidden struggle waged by secret networks around the world to destroy European imperialism

The end of Europe’s empires has so often been seen as a story of high politics and warfare. In Tim Harper’s remarkable new book the narrative is very different- it shows how empires were fundamentally undermined from below by young radicals from across Asia. They gathered in the great cities of Asia - Calcutta, Singapore, Batavia, Hanoi, Tokyo, Shanghai, Canton and Hong Kong - and plotted the end of the colonial regimes with ceaseless ingenuity, both through persuasion and terrorism. Many were caught and killed or imprisoned, but others would go on to rule their newly independent countries.

Drawing on an amazing array of sources, Underground Asia turns upside-down our understanding of twentieth-century empire. The reader enters an extraordinary world of stowaways, false identities, secret codes, cheap firearms, assassinations and conspiracies, as young Asians made their own plans for their future.
