Khazaria on the Dniepr
There is a notion that Kiev may have started as a Khazar outpost before being taken over by the Varangians.
WI this was more firmly established?
So let's suppose as POD that in the early 9C there was a rebellion among the Slavs inhabiting the Kiev area concomitant with the troubles that included the Magyar migration to the western Ukrainian steppe. The rebels manage to ambush and kill a member of the ruling Khazar dynasty. This, for the sake of the honor of said dynasty, requires stronger measures than otherwise would have been considered necessary - to wit the planting of a fairly substantial garrison on the site of Kiev. This garrison starts to attract Khazar settlers. (By the 9C most Khazars, appear to have settled down in sedentary, farming villages.) It is progressively strengthened as the Magyars to the south are getting more and more independent.
Ca. 860: The first Varangian adventurers (Askold and Dir) appear on the scene. The Khazar garrison is just strong enough to repel their assault. (Obviously these Varangians aren't in a position to attack Constantinople.)
Ca.880: A second Varangian attack requires the sending of a relief army from Sarkel to repulse.
From 890 onward: Pecheneg attacks wipe out the sedentary Khazar population of the Don-Volga area and drive the Magyars into Hungary. A lot of sedentary Khazars seek refuge in the Kiev area. Cut off from the khagan's domains the local prince becomes de facto independent (though he continues to pay tribute for about a century). Under the predatory raids of the Pechenegs Slavs and Khazars are thrown together. The ruling prince actively spreads the Jewish faith amongst his subjects.
10C: The new Khazar kingdom spreads over the Dniepr basin from the edge of the steppe north to surroundings of [Smolensk], assimilating (not all that peacefully) its Slavic population. Despite the Pechenegs trade relations are maintained with Byzantium.
