Polish natives left Poland for several reasons including religious and cultural persecution, economic issues in the area and over population. Census taken in 1910 showed there were nearly a million people who had left Poland in the mid to late 1800s to try to find a better life in America.
Polish people had come to America long before the mass influx of immigrants starting in the 1800s The first Poles were the skilled craftsmen that came to take advantage of the opportunities in America. The Polish people who came later were mostly unskilled or farmers who were often uneducated as well. The Mid-West became home to a large number of these farmers because they could continue to farm here. Many Poles moved into factory work, however, to keep their families fed and a roof over their heads.
