There is supposed evidence to suggest
ROFL :):):)
Copernicus' father was a treasurer of Zwiazek Jaszczurczy (Lizard Organisation) an organisation involved in protecting Polish interests against these of Teutonic Order. Among other things they co-financed the 1466 war between Poland and the Order
Well...why do you leave out the important fact:
Lizard Union (medieval), an organization of Prussian nobles and knightsopposed to the Teutonic Knights
Now you have it! Nickis father wasn't not only not a Pole but a Prussian knight and his mama was from a wealthy German merchants family!
Bingo!!!
(Thank you Luki)PS: Luki, you really should read more about these conflict Copernicus and others were involved in (also the Lizard union). It has nothing to do with a Polish freedom fight:
The war started as an uprising by Prussian cities and the local nobility with the goal of gaining independence from the Teutonic Knights. The Prussian Confederation asked the Polish king for help and offered to incorporate Prussia into the Kingdom of Poland. When the king agreed, war between Poland supporting one faction of the Prussians against the Prussians in support of government by the Teutonic Knights broke out. It ended with the Second Peace of Thorn (1466) in favor of the confederacy and Poland, and was followed by the War of the Priests, about independence of the Prussian priests against Poland from 1467-1479.

It was an inter-Prussian civil war, not a Polish-germane war!
