Multi-cordoned Ware culture or Multiroller ceramics culture, translations of the Russian: Kul'tura mnogovalikovoj keramiki (KMK), also known as the Multiple-relief-band ware culture, the Babyno culture and the Mnogovalikovaya kul'tura (MVK), are archaeological names for a Middle Bronze Age culture of Eastern Europe.
From approximately the 22nd to 18th centuries BCE, it occupied an area stretching from the Don to Moldavia, including Dnieper Ukraine, Right-bank Ukraine, and part of the modern Ternopil Oblast, and was bordered by the Volga to the east.
KMK succeeded the western Catacomb culture.
In 1929, the archaeologist Ya. Brik studied four kurgans of this culture near Ostapye village, currently in Ternopil Raion, Ukraine. He found ceramics, flint tools, bone and bronze decorations. Bottoms, walls and ceilings of the graves are layered with rocks. Skeletons are laid in contracted position towards the east.
The name of this culture is related to its ceramic goods, such as pots, which were decorated with multiple strips of clay (cordons) before firing. The culture also featured various other distinctive ornaments
Circumstantial evidence links KMK to the spread of one or more Indo-European languages. Leo Klejn identifies its bearers with the early Thracians. Other scholars suggest that KMK may have been connected to the Bryges and/or Phrygians.
It was increasingly influenced, assimilated and eventually displaced by the Timber grave or Srubna/Srubnaya culture. In c. 2000 - 1800 BCE bearers of KMK migrated southward into the Balkans.
