Zalesye

Zalesye (Russian: Зале́сье; literally: "area beyond the forest") or Opolye (Опо́лье; literally: "area in the fields") is a historical region of Russia, comprising the north and west parts of Vladimir Oblast, the north-east of Moscow Oblast and the south of Yaroslavl Oblast. As a kernel of the medieval state of Vladimir-Suzdal, this area played a vital part in the development of Russian statehood.
