The Homestead Act was passed in 1862 to encourage settlement of the Great Plains by offering citizens 160 acres of government land if they improved the land by building a home and planting crops within 5 years. While the requirements seemed easy, many settlers lacked farming experience and the land was dry, making farming difficult. Less than half of the 2 million people who claimed land under the Homestead Act lived there long enough to own it. Pioneers built homes out of sod blocks when wood was scarce.
