Polish colonial empire

Re: population - until mid-XVII C. Poland-Lithuania had a higher population than Russia.

The comparisons were with Poland alone compared to all Russian-speaking territory (colonizer and colonies respectively).

In a way PLC did become a Polish colonial project in Ukraine once the Lithuanian model unraveled, except it really did not work. Very slow population movement and constant rebellions.
 
How about interwar Poland actually convincing France or Britain to share with them some spoils taken from Germany?
