What happened just prior to 1066? Because I'm pretty sure all that happened immediately after was vengeance the permanent destruction and physical "blockade" of a certain "empire" by Russia:

In the Russian chronicle, the vanquishing of the Khazar traditions is associated with Vladimir's conversion in 986.[127] According to the Primary Chronicle, in 986, Khazar Jews were present at Vladimir's disputation to decide on the prospective religion of the Kievan Rus'.[128] Whether these were Jews who had settled in Kiev or emissaries from some Jewish Khazar remnant state is unclear. Conversion to one of the faiths of the people of Scripture was a precondition to any peace treaty with the Arabs, whose Bulgar envoys had arrived in Kiev after 985.[129]

A visitor to Atil [one of 3 major Khazar cities] wrote soon after the sacking of the city that its vineyards and garden had been razed, that not a grape or raisin remained in the land, and not even alms for the poor were available.[130] An attempt to rebuild may have been undertaken, since Ibn Hawqal and al-Muqaddasi refer to it after that date, but by Al-Biruni's time (1048) it was in ruins.[note 42]
