https://en.wikipedia.org/wiki/Feudalism
wikipedia redirects "Prussia" to "Feudalism" (which i read about before wikipedia attacked the subject with fake news, thank you) - depicting prussia (per say, redirected) as being full of castles armies and wars. IT WAS NONE OF THOSE, it was the outlands, farms, very small farming towns (minks ,where farming trade happened).
Prussia has zero to do with feudalism.
Feudalism was an outbreak of war throughout europe - noting england was part of it, where wars were between "white families" (tribes) because law had completely been set aside (there was no laws)
after 100 years of continual bloodshed, finally legal agreements were made to settle feudal disputes "IN COURTS" and feudalism itslef (war between families not ordained by the kings) WAS OUTLAWED
