Effect the homestead act have on westward expansion

law in May 1862, the Homestead Act opened up settlement in the western United States, allowing any American, including freed slaves, to put in a claim for up to 160 free acres of federal land. By the end of the Civil War, 15,000 homestead claims had been established, and more followed in the postwar years. Eventually, 1.6 million individual claims would be approved; nearly ten percent of all government held property for a total of 420,000 square miles of territory.
