Chorni Klobuky [Чорні Клобуки; Black Hats]. The name that appears in Kyivan Rus’ chronicles for the Turkic tribes (known also as Torks) that at the end of the 11th century settled south of Kyiv principality and Pereiaslav principality. The name is derived from the headdress of these tribes. In the 12th century some of the Chorni Klobuky changed to a settled form of life. The Rus’ princes used them for the defense of their southern borders.
