@Nata61947452@stellarprism_@juliet2138 It's mentioned later, but this doesn't mean it wasn't there. And it doesn't mean that Kiyevan Rus became Kiyevan after 882 conquer, and to be precise, here weren't only "Kiyevan Rus". There were other territories which call themselves " X Rus"
@Nata61947452@stellarprism_@juliet2138 Moscow is Moscow, Russia is Russia, the thing is that Moscow had permission to gather taxes for Horde, so they became rich and powerful, and later it "unite" all the other cities.
@stellarprism_@Nata61947452@juliet2138 And the last thing - "Kiyevan Rus" is a historical termin made up later, nobody calls this territory like this during its existence.
