The Homestead Act of 1862 encouraged 600,000 families to settle the West by giving them land (usually 160 acres) almost free. They had to live on and improve the land for five years. Before the American Civil War, Southern leaders opposed the Homestead Acts because they feared it would lead to more free states and free territories. After the mass resignation of Southern senators and representatives at the beginning of the war, Congress was subsequently able to pass the Homestead Act.
