Vladimir-Suzdal (Russian: Владимирско-Су́здальская, Vladimirsko-Suzdal'skaya), also Vladimir-Suzdalian Rus',[1][2] formally known as the Grand Duchy of Vladimir (1157–1331) (Russian: Владимиро-Су́здальское кня́жество, romanized: Vladimiro-Suzdal'skoye knyazhestvo, lit.'Vladimiro-Suzdalian principalty'; Latin: Volodimeriae[3]), was one of the major principalities that succeeded Kievan Rus' in the late 12th century, centered in Vladimir-on-Klyazma. With time the principality grew into a grand duchy divided into several smaller principalities. After being conquered by the Mongol Empire, the principality became a self-governed state headed by its own nobility. A governorship of principality, however, was prescribed by a Khan declaration (jarlig) issued from the Golden Horde to a noble family of any of smaller principalities.
