Mother Russia. Who is she?

[mlmaos.livejournal.com]

In the fan-works and commentaries Ivan often says "One with Mother Russia" or the variant of the phrase - "One with Russia."

I think that the reason for the joke - a historical feature of nicknames and the image of Russia.
But if this opinion can be given up - what do you think?
Who is the Mother Russia? Or why does Ivan (if he says about himself) seriously identify himself so?
