A federal law that gave settlers 160 acres of land for about $30 if they lived on it for five years and improved it by, for instance, building a house on it. The act helped make land accessible to hundreds of thousands of westward-moving settlers, but many people also found disappointment when their land was infertile or they saw speculators grabbing up the best land. This originally consisted of grants totaling 160 acres of unappropriated federal land within the boundaries of the public land states.
