The General Land Office (GLO) (1812 - 1946) was an independent agency of the United States government responsible for public domain lands in the United States. Created in 1812, it took over functions previously conducted by the Department of the Treasury. The GLO oversaw the surveying, platting, and sale of public lands in the western United States. It also administered the Preemption Act of 1841, which allowed individuals who were already living on federal land to purchase up to 160 acres of land before it was offered for sale to the general public, if they met certain requirements. Following the passage of the Homestead Act in 1862, which was also administered by the GLO, claims under the Preemption Act sharply decreased. The GLO became a part of the newly-created Department of the Interior in 1849. In 1891 Grover Cleveland and Congress created 17 forest reserves, due to public concern over forest conservation, which were initially managed by the GLO, until they were transferred to the Forest Service in 1905. In 1946 the Government Land Office was merged with the United States Grazing Service to become the Bureau of Land Management. Today the Bureau of Land Management administers the roughly 246 million acres of public land remaining under federal ownership. Learn More...
