In the beginning, by which I mean before 1054, the Church was united, though the Eastern and Western pieces had lots of theological differences, which they could just not iron out. But then it was 1053, and the Patriarch of Constantinople closed all the Latin churches in the city, and after that, the Pope of Rome tried to get the Patriarch to recognize him (the Pope) as the head of the Church, which he wouldn't, and then they excommunicated each other, and we had The Great Schism of 1054. But there was still lots and lots of trade between the East and the West, because money, which is why in 1182 there was a large Italian population of traders and their families in Constantinople, especially since they'd been given lots of economic incentives, and so they were making lots of money and shouldering all of the Byzantine traders out, and also, alas, the Italians were VERY arrogant and annoyed everybody, besides which they were very badly behaved, and a mob that had been celebrating the entrance into the city of their new emperor Andronikos pivoted and began massacring all of the Italians they could find in the city. This was very bad. Very bad indeed. And it didn't help the East-West relations, which would be reaching their nadir with the Sack of Constantinople in 1204, after which the East and the West wouldn't even speak to each other, for hundreds of years. We explain the massacre and Michelle finds novels, including one by, I kid you not, Louis L'Amour, who apparently had a sort of cowboy take on the whole shebang.

Mikhail of Chernihiv, the Grand Prince of Kyiv and Prince of Chernihiv, went to several neighboring states to ask for help fighting the Golden Horde -- he had the idea that there would be strength in alliance -- but nobody would help, on account of they were too busy fighting each other, and also the Mongols had not actually gotten to their houses yet, so why should they care. Then the Golden Horde destroyed Kyiv, and told Mikhail he had to come give obeisance to Batu Khan, and he did that, but he wouldn't worship idols, which was part of the deal, so the Golden Horde executed him. And then he pretty quickly became venerated, and then a saint as a martyr, and his relics were taken to Chernihiv but now they are in Moscow. Besides all that, MIchelle is totally impressed by the number of his vitae surviving. Also that Batu Khan is connected to Russian Atlantis. Also there is a kangaroo. (Spoiler alert: the Golden Horde did in fact get to those other neighboring states, after they had finished looting Kyivan Rus.)

King Duncan did indeed get killed, in 1040, and Macbeth was around, and maybe even was near him at the time, but Duncan wasn't old, he wasn't asleep in bed, and there was no crime, because Macbeth's forces slaughtered Duncan's forces in battle, and Duncan was one of the slaughtered. In this episode, Anne explains all of the history that can be explained -- it's a slippery bunch of facts, but there was a King Duncan, he did die, and Macbeth was king after him. Michelle explains the historical sources, and mentions the novels, but really what she wanted to know was where the hell that theatre superstition about not ever saying the title of the Scottish Play in the theater, at pain of being made to do whatever silly things are in fashion at the time -- well, where the hell that came from. And we want to know, too.
