![Lord Louis Mountbatten, the last Viceroy of India, and his wife, Lady Edwina Mountbatten, ride in the state carriage towards the Viceregal lodge in New Delhi, on March 22, 1947 [File: AP]](https://www.aljazeera.com/mritems/imagecache/mbdxxlarge/mritems/Images/2018/12/13/3a4683d7f99349baa4791de15b662965_18.jpg "How Britain stole $45 trillion from India")
There is a story that is commonly told in Britain that the colonisation of India - as horrible as it may have been - was not of any major economic benefit to Britain itself. If anything, the administration of India was a cost to Britain. So the fact that the empire was sustained for so long - the story goes - was a gesture of Britain's benevolence.
New research by the renowned economist Utsa Patnaik - just published by Columbia University Press - deals a crushing blow to this narrative. Drawing on nearly two centuries of detailed data on tax and trade, Patnaik calculated that Britain drained a total of nearly $45 trillion from India during the period 1765 to 1938.
It's a staggering sum. For perspective, $45 trillion is 17 times more than the total annual gross domestic product of the United Kingdom today.
How did this come about?
