Why was the homestead act such a significant factor in the westward migration?

They gave migrants land for moving west, to encourage migration and spreading out.

Explanation:

"Signed into law by President Abraham Lincoln on May 20, 1862, the Homestead Act encouraged Western migration by providing settlers 160 acres of public land. In exchange, homesteaders paid a small filing fee and were required to complete five years of continuous residence before receiving ownership of the land."

Hope this helps!!
