Flour from Minneapolis moved by rail to destinations on the East Coast but also to ports where it was shipped to Europe. The high quality and low cost threatened local industries in places like England, France, and Germany (in 1878, 10% of Minneapolis's flour went to Great Britain). In Poland, Minneapolis flour undersold local flour; many small farmers who could no longer make a living were forced off their land and came to America on the same ships that had carried the flour.
