India's history, culture, tradition and trade have been inextricably linked to travel through the ocean - the Indian Ocean - for thousands of years. We are in many senses the product of this flow of culture, as are other parts of South Asia, which have taken essential aspects of India's civilisation and faith and adopted them as their own. Despite this incredibly rich heritage, people often don't think of India as a maritime state, and rarely consider the critical importance of the geographic location within the Indian Ocean. We are a peninsular nation, profoundly so, but how often do we see ourselves as being a part of that? In his book, the "Incredible History of the Indian Ocean", Sanjeev Sanyal, who many would better know as the Principal Economic Advisor to governments, offers a concise and easy-to-read account of this part of our history. It's meant for the younger reader, but it's well worth reading for anyone interested in the subject.
