I, too, would like to know when people consider the Dark Ages to be officially over as you can't really answer the first question until you have a rough idea of this. Jamie, or anyone, please correct me if I am wrong (because I probably am wrong) ???This is a difficult question to answer because I don't have the facts to hand but the Dark Ages, if memory serves, was considered to cover a substantial amount of the Middle Ages (I don't know how much but let's say probably well into the 12th or 13th century - to the end of the High Middle Ages) however, after a great of deal academic arguing over the years this school of thought has changed. Now, the Dark Ages is most likely considered to cover a period up to the end of the migration/invasion period of the Angles, Saxons and Jutes (6th or 7th century - about three quarters of the Early Middle Ages) or even earlier. With the lack of primary sources and conflicting secondary sources I don't know how long it will take to effectively cover this period but we should have a few episodes yet. It certainly won't take as long as the Roman Occupation unless Jamie, and his untiring research can eke it out that long but I doubt it. This is mostly off the top of my head so it is probably best if someone else can clarify in more detail the answer to your questions.
