Empires of the Indus: From Tibet to Pakistan - The Story of a River

One of the largest rivers in the world, the Indus rises in the Tibetan mountains, flows across northern India and then through Pakistan. For millennia it has been worshipped as a god, for centuries used as a tool of imperial expansion; today it is the cement of Pakistan's fractious union. This recounts a journey along the Indus, upstream and backwards in time, through two thousand miles of geography from the sea to the source; travelling back historically, from the moment that Pakistan first came into being in Karachi, to the time, millions of years ago in Tibet, when the river itself was born.
