As additional lands were acquired by the United States from [[Spain]], [[France]], and other countries, [[Congress]] directed that they be explored, surveyed, and made available for settlement. In 1812, Congress established the General Land Office in the [[Department of the Treasury]] to oversee the disposition of these Federal lands. As the 19th century progressed and the Nation's land base expanded further west, Congress encouraged the settlement of the land by enacting a wide variety of laws, including the [[Homesteading Laws]] and the Mining Law of 1872. | As additional lands were acquired by the United States from [[Spain]], [[France]], and other countries, [[Congress]] directed that they be explored, surveyed, and made available for settlement.
