Peter Frankopan is a historian who likes to take on big ideas, sweeping across many centuries and national boundaries. In his acclaimed book The Silk Roads: A New History of the World, published in 2015, he argued that the Persian empire gave rise to the West and he explored the importance of the trading routes that linked Arabia and Asia to Europe, and how they spread ideas, culture and religion. The book was a bestseller in the UK, China and India and even inspired a musical collaboration between singer Katie Melua and students at Oxford, where Peter is professor of global history. His follow-up, The New Silk Roads: the Future and Present of the World investigated how economic power is shifting eastwards. More recently Peter has turned his attention to climate change. In The Earth Transformed he examined how it has dramatically shaped the development - and the demise - of civilisations across time. Peter's musical choices include works by Tchaikovsky, Mozart and Edward Naylor.
