In the antebellum south, slaves did free labor. Slaves were considered property, and they were property because they were black. Their status as property was enforced by violence -- actual or threatened. Besides planting and harvesting, there were numerous other types of labor required on plantations and farms. Enslaved people had to clear new land, dig ditches, cut and haul wood, slaughter livestock, and make repairs to buildings and tools. In many instances, they worked as mechanics, blacksmiths, drivers, carpenters, and in other skilled trades. Black women carried the additional burden of caring for their families by cooking and taking care of the children, as well as spinning, weaving, and sewing.
Some slaves worked as domestics, providing services for the master's or overseer's families. These people were designated as "house servants," and though their work appeared to be easier than that of the "field slaves," in some ways it was not. They were constantly under the scrutiny of their masters and mistresses, and could be called on for service at any time. They had far less privacy than those who worked the fields.
In 1945, after the defeat of Nazi Germany, Poland's borders were redrawn in accordance with the decisions made first by the Allies at the Tehran Conference of 1943 where the Soviet Union demanded the recognition of the military outcome of the top secret Nazi–Soviet Pact of 1939 of which the West was unaware. Hope this helps :)
