Besides the town proper there are three considerable suburbs . Though founded in 993 by Vladimir the Great of Moscow in memory of his signal success over the Turkish Pechenegs, Pereyaslavl has now few remains of antiquity . The town has a trade in grain, salt, cattle and horses, and some manufactures —tallow, wax, tobacco, candles and shoes . From 1054 Pereyaslavl was the chief town of a separate principality . As a southern outpost it often figures in the 11th, 12th and 13th centuries, and was plundered by the Mongols in 1239 . In later times it was one of the centres of the Cossack movement; and in 1628 the neighbourhood of the town was the scene of the extermination of the Polish forces known as " Tara's Night." It was by the Treaty of Pereyaslavl that in 1654 the Cossack chieftain Bogdan Chmielnicki acknowledged the supremacy of Tsar Alexis of Russia .
