I just say some stuff to p*ss you off pal.
Thats to say Ukraine was a depopulated wasteland, courtesy of the Mongols, Tartars and your own warring Ruthenian nobility, you had exactly one major city - Kiev.
By that time Poland had Poznań, Kraków, Gniezno... all in all Poland had 32 major cities, six of which were the size of Kiev.
Thats not counting smaller cities and towns, you guys were two barns and a cow.
