On the eve of the civil war, the population of the United states was approximately 32 million people ( both black and white), of which 20 million lived in the North. Nearly one million Americans worked in industry and manufacturing rather than agriculture so there was no shortage of people to work in factories.
Many thousands of people moved from rural areas to cities to find jobs. Recently arrived immigrants took jobs in factories just to get started in America. Men, women and children worked in factories often for long hours and very little pay.
Also during the civil war, Northern cities and their industries remained untouched and so manufacture and production of goods went on as usual.
Between 1945 and 195, the Soviet policies affect the history of Eastern Europe in such way that Europe was divided into two and this was because of an arguments that are over political organization of a Europe which are liberated from Nazi Germany.
