Historian Michael Scott continues his journey through Sicily, tracing the island's story through the arrival of the Muslim Arabs and then the Normans - times in which religious and cultural tolerance was the order of the day. Michael explores the dark days of the Spanish inquisition and then delves into the modern world - the unification with Italy and the rise of the Mafia. Today, Sicily faces a new challenge. The island is on the frontline of Europe's migrant crisis but the Sicilian response, formed in part by their own turbulent history, may well surprise many north Europeans.
