At the beginning of the eighteenth century, as the British economic historian Angus Maddison has demonstrated, India's share of the world economy was 23 per cent, as large as all of Europe put together. (It had been 27 per cent in 1700, when the Mughal Emperor Aurangzeb's treasury raked in PS100 million in tax revenues alone.) By the time the British departed India, it had dropped to just over 3 per cent. The reason was simple: India was governed for the benefit of Britain. Britain's rise for 200 years was financed by its depredations in India.
