They defeated the mightiest Empire of that time – the Golden Horde, liberated their small city and conquered a lot of territory which was once known to be ruled by the people of Rus, and they took their name because there was no one as legitimate successor. They are still global powerhouse so who cares if they are not “the Rus”?

Muscovite early statehood is really not much different then the early statehood of Slavs in eastern and central Balkans. Except Balkan Slav rulers of that time had wet dreams to conquer Byzantine empire instead of Golden Horde and this period in Balkans started earlier, in 7th – 8th century.

Today they certainly have good and bad sides, but in reality they’re not much different to what any of the other Slavic nations would be if they’re global force.
