Neolithic European culture that arose in Ukraine between the Seret and Bug rivers, with extensions south into modern-day Romania and Moldova and east to the Dnieper River, in the 5th millennium BC. The culture's characteristic pottery was red or orange and was decorated with curvilinear designs painted or grooved on the surface. Its makers occupied villages of long, rectangular houses that were sometimes arranged in concentric circles. In the centre, cattle were fenced in an enclosure. The Trypillya people practiced shifting agriculture, frequently moving their settlements.
