Millions of eastern Europeans, many Polish people were taken from their homes and brought to Germany as forced laborers during WW2. Some died in the fighting and bombings. They were put in DP (Displaced Person) camps after the war and couldn't go back because the Soviets redistributed lands (and they didn't want to live under communism). 

They eventually settled in the US, Canada, and Australia and experienced prejudice for their DP status (dumb polack). 

The point is there are alot of bridges to be built between Poles and black people in the US.

During WW2, there was an SS-sponsored program where a lot of Slavic (mostly Polish) children were stolen from their families, inspected for “good” racial qualities, and if they passed, they were put into facilities where they were banned from speaking Polish and forced to learn German culture and language, brainwashed into forgetting their birth parents, had their birth records destroyed, and eventually adopted out by German parents in a process called Germanization. Children who put up too much of a fight were sent to concentration camps to die. Nobody really knows the specific number of children taken, different sources estimate it to be anywhere between 10,000 and 200,000. To this day, there are many old people who remember and are still trying to find long-lost family members, learn about their own true origins, and German elderly who have no idea they aren’t even actually German. Sometimes people who did find their family members are rejected due to denial. It’s really sad.

This probably sounds familiar to Americans because of how similar this is to the residential schools dedicated to stripping indigenous children’s culture. It’s called Lebensborn if anyone wants to look it up. There are some documentaries on YouTube as well.
