In Kievan Rus', as well as Appanage and early Muscovite Russia, collateral succession, rather than linear succession, was practiced, with the throne being passed from the eldest brother to the youngest brother and then to cousins until the fourth in line of succession (not to be confused with "fourth cousins") in a generation before it was passed on to the eldest member of the senior line if his father had held the Kievan throne. The princes were placed in a hierarchy or "ladder" or "staircase" of principalities, which Sergei Soloviev called the "rota system" (rota being the Old Church Slavonic term for a ladder or staircase), with Kiev as the pinnacle. When the grand prince of Kiev died, the next prince on the ladder moved up the ladder, and the rest advanced a rung as well.
