The tatars ...would settle in polish lithuania, and soon 300,000 thousand would live in poland.
Excuse me, but where is this quotation from? Daily Mongol? Mongolskaya Gazeta?
The fact is that in Poland there are only from 500 to 3000 (at most) Tatars...
pl.wikipedia.org/wiki/Tatarzy_w_Polsce
...they live in peace among us, but their influence on Polish culture (and gene pool) is rather limited, to put it mildly.
I understand that it's rather difficult for you to accept this fact, but here it is - pure science, facts, and common sense: Poland is
the only Slavic country in the world (as I explained earlier in this thread). There are many Slavic wannabies, but Polska is the Mother of all Slavija, and even Crow admits that.
I highly recommend the book:
... that explains the unique position of Poland among the nations.
