In 1240 the city of Kiev was destroyed by the Mongols, whose leader, Batu Khan, is reported to have boasted: "I will tie Kiev to the tail of my horse. " In the ensuing centuries, Kiev and the surrounding territory continued to be the target of Tatar raids. From 1450 to 1586, for example, eighty-six raids were recorded, and from 1600 to 1647, there were seventy more. Crimean Tatars sacked Kiev in 1416 and again in 1482. Kiev was not ravaged again until the mid-seventeenth century, but even during this long period of comparative peace, it did not recover the size or importance it had enjoyed as the capital of Kievan Rus. According to one set of figures, Kiev had about three thousand residents early in the fifteenth century. Lviv (Lvov), Ukraine's largest town at this time, had about ten thousand.In 1474 one Venetian visitor described Kiev as "plain and poor." Statistician Ivan Pantiukhov estimates that its population averaged no more than ten thousand inhabitants from the fourteenth through the seventeenth centuries.
