Please stop displaying your ignorance. Those maps were drawn based on data from Russian census records.==
Prove it. Russian census records didn’t count ukies. In Russian records ether are Velikorosses, Malorosses, Belorosses. It was SOVIET commie records which counted ukies. And those are absolutely unreliable.
Good grief. Malorossiya is just archaic name for Ukraine. There is no difference in the territory or people they describe.
