Rus' Khaganate
Khazaria nonetheless left its mark on the rising states and some of their traditions and institutions. Much earlier, Tzitzak, the Khazar wife of Leo III, introduced into the Byzantine court the distinctive kaftan or riding habit of the nomadic Khazars, the tzitzakion (τζιτζάκιον), and this was adopted as a solemn element of imperial dress. The orderly hierarchical system of succession by "scales" ("lestvichnaia sistema":лествичная система) to the Grand Principate of Kyiv was arguably modelled on Khazar institutions, via the example of the Rus' Khaganate.
