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. As you get to 1015, it's taken even more territory and by 1113, which is near the peak of the Kievan state, you see that it has taken control of a good chunk of Eastern Europe. And as the state expands, its character changes as well. As you get to the end of the 10th century, you have a major event in one of Rurik's descendants, Vladimir, often known as Vladimir the Great.
