Vladimir-Suzdal' Principality, or Vladimir-Suzdal' Grand Duchy was one of major principalities after the collapse of the Kievan Rus'. It occupied vast territory approximately bounded by Volga, Oka and Northern Dvina. Its capital was Vladimir during 1157-1238. Vladimir city was founded by Vladimir Monomakh in 1108 and was destroyed by Mongol invasion in 1238. The second important city was Suzdal', also destroyed by Mongols.
