In ‘Tales from the Caspian Sea’, Bettany Hughes investigates the rich cultural history of the Caspian, a region which nourished the ancient world’s oldest theocracy, in the form of a Zoroastrian state, and pioneered an early Muslim-majority democracy in 1918. Her investigation of Azerbaijan - “the land of fire” - begins in the foothills of the Caucasus Mountains with visits to the archaeological sites that are actively reanimating the history of the region.
