The Mongol Empire invaded and conquered much of Kievan Rus' in the mid-13th century, sacking numerous cities including the largest: Kiev and Chernigov. The siege of Kiev in 1240 by the Mongols is generally held to mark the end of the state of Kievan Rus', which had already been undergoing fragmentation. Many other principalities and urban centres in the northwest and southwest escaped complete destruction or suffered little to no damage from the Mongol invasion, including Galicia–Volhynia, Novgorod, Pskov, Smolensk, Polotsk, Vitebsk, and probably Rostov and Uglich.
The Golden Horde, self-designated as Ulug Ulus, was originally a Mongol and later Turkicized khanate established in the 13th century and originating as the northwestern sector of the Mongol Empire.

It is also known as the Kipchak Khanate or the Ulus of Jochi, and replaced the earlier, less organized Cuman–Kipchak confederation.

With time the principality grew into a grand principality divided into several smaller principalities.
