Back when Lithuania was still pagan it became involved in expanding into the territories of the East Slavs, the former Kievan Rus Empire. From what I heard, they were fairly popular with their East Slav subjects. I was wondering what if they succeeded, incorporating Novgorod and Muscovy/Vladimir-Suzdal. For example, Vytautas could have married a Rurikid princess, which would have helped his claim. What would have been the results? Lithuania would no doubt have been converted to Orthodoxy instead of Catholicism. There would have basically been a new Kievan Rus, but whose upper most ruling elite would have been mainly Lithuanian. Questions? Comments?
