Delighted to have Professor Ed Watts back on the show. This time he is talking about the 4th Crusade which turned into one of history's great catastrophes. People give many possible dates for the fall of the Roman Empire and Ed argues persuasively for 1204 when the crusade reaches its heartbreaking climax.
