Why were the Great Plains settled so quickly?

The Great Plains were settled quickly due to several factors, including the promise of fertile land offered by the Homestead Act of 1862, which provided 160 acres to settlers willing to farm the land for five years. Additionally, advancements in transportation, such as the expansion of the railroad network, made it easier for settlers to reach and transport goods from these remote areas. The allure of economic opportunity and the availability of resources, coupled with a growing population in the eastern United States, further accelerated the migration to the region.
