Jago begins by journeying through southern Mexico to investigate the rise and fall of America's oldest civilisation, the Olmec, who thrived over 3,000 years ago. He encounters colossal stone heads and the oldest rubber balls in the world and descends deep inside an ancient cave network in search of a were-jaguar.
In the region that includes the Mediterranean, the Aegean, Mesopotamia and Egypt, the Bronze Age arrived about 3000 BC and lasted nearly 2000 years. What singled out this period and the new societies and cities that emerged? The development of formal writing is one among several important factors.
Our third and final episode looks at the Ottoman Empire’s slow decline in the face of Russian expansion and explores the complex alliances it would forge with European powers in an effort to survive. The map of Europe would be radically redrawn and the Ottoman Empire would come to a humiliating end, giving birth to the modern Turkish Republic.
He continues his personal account of Britain's empire by looking at how traders, conquerors and settlers spread the British way of doing things around the world - in particular how they created a very British idea of home. He begins in India, where early traders wore Indian costume and took Indian wives. Their descendants still cherish their mixed heritage. Victorian values put a stop to that as inter racial mixing became taboo. In Singapore he visits a club where British colonials gathered together, in Canada he finds a town whose inhabitants are still fiercely proud of the traditions of their Scottish ancestors, in Kenya he meets the descendants of the first white settlers - men whose presence came to be bitterly resented as pressure for African independence grew. And he traces the story of an Indian family in Leicester whose migrations have been determined by the changing fortunes of the British empire.
