How did the Homestead Act of 1862 affect settlement on the Great Plains?

The Homestead Act of 1862 was a pivotal driver of settlement on the Great Plains, encouraging hundreds of thousands of people to migrate westward in pursuit of "free land."12

By granting 160 acres of unappropriated public land to individuals who paid a small fee and committed to improving the property over five years, the act facilitated a massive internal migration. Settlers, including families, single women, immigrants, and African Americans—such as those participating in the Exoduster Movement—flocked to regions like Kansas, Nebraska, and the Dakota Territory.132

While the act successfully incentivized the occupation of lands previously inhabited by Indigenous communities, it also introduced significant environmental challenges. Many new farmers, often called "sodbusters," applied agricultural practices from the East that were ill-suited to the semiarid climate of the Great Plains. By removing native grasses and deep-plowing the soil, these settlers inadvertently contributed to conditions that would later lead to the Dust Bowl. Ultimately, the legislation distributed approximately 270 million acres, with about 80 million acres successfully claimed by small farmers by the early 20th century.21
