I just grabbed that number from wikipedia when I noticed that the Vox article you linked didn't go back to the Mongol invasion.
That seems to be a period of colonialization that doesn't come up all that much, but because of how it changed the Rus culture of Moscow I've been thinking about quite a bit for a few years.
