Ashoka was the ruler of a vast empire in the 4th Century BC which included nearly all of India. He is known today from both archaeological evidence (a series of pillars & rocks inscribed with his edicts) and textual evidence (later Buddhist histories). The three experts who discussed him on In Our Time were Jessica Frazier (University of Kent and the Oxford Centre for Hindu Studies), Naomi Appleton (University of Edinburgh) and Richard Gombrich (Oxford Centre for Buddhist Studies and University of Oxford).
Started off the evening with the third episode of Andrew Marr's History of the World - this one was about the Word and the Sword, basically the rise and spread of Buddhism, Christianity & Islam with a few side stories. He started off with the story of Ashoka who killed and conquered his way to ruling an empire that covers most of modern India. But then after witnessing the appalling slaughter he himself had caused he converted to Buddhism and spent the rest of his (long) reign promoting peace and tolerance throughout his land and actively spread Buddhism as a religion.
This third part of the series on the Written Word was covering how books and writing helped the spread of global religions during the first millennium AD. And also how the needs of the religions helped spread literacy & printing. It was split into 3 sections - covering Christianity, Islam and Buddhism. Common to all three is the way that once the words are written down it's easier for prospective converts to find out about the religion in question, so it's easier for it to spread.
