Signed into 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.
The Homestead Act (May 20, 1862) set in motion a program of public land grants to small farmers. Before the Civil War, the southern states had regularly voted against homestead legislation because they correctly foresaw that the law would hasten the settlement of western territory, ultimately adding to the number and political influence of the free states. This opposition to the homestead bill, as well as to other internal improvements that could hasten western settlement, exacerbated sectional conflicts. Indeed, the vision of independent yeomen establishing homesteads on the prairies was offered in the political rhetoric of the 1850s as a vivid contrast to the degradation of slave labor on southern plantations. A homestead bill passed the House in 1858 but was defeated by one vote in the Senate; the next year, a similar bill passed both houses but was vetoed by President James Buchanan. In 1860, the Republican platform included a plank advocating homestead legislation.

New Dealers argue the economy was already improved before the war had any significant impact. Opponents believe the war was the only impact citing the 1937 recession as evidence.
