Polish–Lithuanian–Muscovite Commonwealth Polish–Lithuanian–Muscovite Commonwealth The Polish–Lithuanian–Muscovite Commonwealth was a proposed state that would have been based on a personal union between the Polish–Lithuanian Commonwealth and the Tsardom of Russia. A number of serious attempts, by various means, to create such a union took place between 1574 and 1658, and even as late as the latter part of the 18th century, but it has never materialized due to incompatible demands from both sides. The proposed union is known in Polish historiography as the "Triple Union" ("unia troista") and has also been called the "Polish–Russian Union" ("unia polsko-rosyjska") or "Polish–Muscovite Union" ("unia polsko-moskiewska").
