And in the early 880s, he goes and establishes himself in Kiev, expanding the land of Rus'. This is Kiev right over here. And because Oleg was able to take Kiev, the state that emerges from Rurik and Oleg, not only is it known as the land of the Rus', but is often known as the Kievan state and they're often known as the Kievan Rus'. And you can see here how that state expands over the next few hundred years. As we get to the year 900, you have this off-white color and you can see it is in control of both Novgorod and Kiev.
