In the nineteenth century, a tiny community from the deserts of Rajasthan spread out to every corner of India. The Marwaris controlled much of the countrys inland trade by the time of the First World War. They then turned their hand to industry and by the 1970s, owned most of Indias private industrial assets. Today, Marwari businessmen account for a quarter of the Indian names on the Forbes billionaires list. What makes the Marwaris so successful? Is it their indomitable enterprise or their incredible appetite for risk? In this new book, Thomas Timberg shows how the Marwaris rely on a centuries-old system for conserving and growing capital which has stood them in good stead, alongside a strong sense of business ethics which has earned them respect. Family businesses in general and the Marwaris in particular might have a vital role to play in shaping Indias economic future.
