Poland was a peaceful country. They mostly farmed for a living. Then they were attacked by Germany because they had a small army and were close by.
One reason the Poles were persecuted was because the Germans needed a labor force.
The men were recruited for the army. The woman and children farmed. Another reason the Poles were persecuted was because so they could inflict fear in other places. One example of it is they often shot the Poles in mass executions. They also tested science experiments on the body’s.
In the end 6 million Poles died. 3 million Catholics, 2,200,000 Christians, and 3 million Polish Jews. All of them were innocent. Nearly half of the Polish population was destroyed.
