Explanation:

The Farmers Alliance movement was an organized agrarian movement that developed during the second part of the 1800s. This movement included several alliances, such as the National Farmers' Alliance and Industrial Union, the National Farmers' Alliance and the Colored Farmers' National Alliance and Cooperative Union. These alliances allowed farmers to improve their situation after the Civil War. They allowed small farmers to borrow machinery, encouraged government regulation of the transportation industry, and tried to ease the burden of loan repayment for small farmers.
