Hello readers, you may have noticed by now that I've already closed the timeline Ivangorod Prosperous: Russia's Early Rise to Power due to the need for a rewrite. It may not end up as Ivangorod though. However, I've got so much ideas for a PoD that I don't know where to start. Here are the ideas that can be considered:
1) All of the Rus' lands are united by Lithuania under the Gediminids, with Jogaila taking the throne as Grand Prince. PoD would either be Jadwiga born as a boy or Jadwiga marries Ladislaus of Naples and becomes the Queen of Hungary. Lithuania also converts to Orthodoxy in this case.
2) Ivan IV's wife Anastasia Romanova doesn't die in 1560, preventing him from becoming insane. A saner Ivan IV would not only prevent the botching of the Livonian Wars, but even have a chance of conquering the Crimean Khanate.
3) A Zoroastrian Russia arising instead of a Christian Russia. PoD could be way back during the Rashidun conquests. Alternatively, a Zoroastrian Khazaria could conquer Kievan Rus'.
4) An integration of Kievan Rus' with the Kipchak-Cuman Confederation with Vladimir Monomakh's other children dying before he marries the daughter of Aepa, Khan of the Kipchaks.
