Kiev in the Golden Horde period
Kiev in the Golden Horde period (Ukrainian: Київ у золотоординські часи, romanized: Kyiv u zolotoordnys'ki chasy) is the chapter in the history of Kyiv from the 1240 Mongol siege and conquest of Kiev until the 1362/3 Battle of Blue Waters, which saw the Grand Duchy of Lithuania emerge as the new hegemon in central Ukraine (see History of Kyiv (1362–1657)). The Mongol invasion of 1237–1242 destroyed the Kievan Rus' state and disrupted traditional economic ties. This had a negative impact on the socio-economic, political and cultural development of Kiev. The Mongol army commander Batu Khan established the Khanate of the Golden Horde, with its capital city of Sarai on the Lower Volga, replacing Kiev as the political centre of the Rus' principalities. However, Kiev remained the de jure and de facto metropolitan see, and thereby the religious centre of Rus', until at least 1299.
