Rus' Khaganate
In Russia, the word "kaftan" is used for another type of clothing: a style of men's long suit with tight sleeves. Going back to the people of various Baltic, Turkic, Varangian (Vikings) and Iranic (Scythian) tribes who inhabited today's Russia along with the Slavic population, kaftan-like clothing was already prevalent in ancient times in regions where later the Rus' Khaganate and Kievan Rus' states appeared.
