How long has the Russian culture been around for? First real answer= 5 stars?

People have lived in Russia since the Paleolithic age. No one knows where the Slavs first came from, but the Vikings penetrated Russia and established a dynasty. The Varangian prince Rurik established himself in Novgorod around the year AD 862.

That would be very difficult to pin down.

If I remember right, the Rus Trading Posts of the Finnish were among the first immigrants to the area.

The natives of the Russian area number in the hundreds of tribes and cultures with over 1000 languages.

Since about 1000AD when all Russia converted to Greek form Christianity and was united under Vladimir the Saint (so for 1016 years). Of course the culture matured over time and became fully mature and set (1470) under Ivan III (the Great). Prior to c.1000AD the pagan Slavic and Scandinavian people, their chiefs and princes weren't really 'Russian' but proto (or pre) Russian.

The first actual Russian identity emerged in late 1AD with Russian Vikings and influences from Finnish and Hungarian, as well as Middle Eastern and Asiatic/Mongolian sources, and Greco-Roman influences in the Greek Orthodox Church. The richness of this mix gave rise to a unique Russian culture expressed in dance, music, painting, sculpture, etc. So, with the birth of a Russian identity in the first century AD, came an incredibly rich cultural heritage.
