A national push for expansion and progress in the United States occurred in the later part of the 19th century, which stimulated interest in draining the Everglades for agricultural use. According to historians, "From the middle of the nineteenth century to the middle of the twentieth century, the United States went through a period in which wetland removal was not questioned. Indeed, it was considered the proper thing to do." Draining the Everglades was suggested as early as 1837, and a resolution in Congress was passed in 1842 that prompted Secretary of Treasury Robert J. Walker to request those with experience in the Everglades to give their opinion on the possibility of drainage. Many officers who had served in the Seminole Wars favored the idea. In 1850 Congress passed a law that gave several states wetlands within their state boundaries. The Swamp and Overflowed Lands Act ensured that the state would be responsible for funding the attempts at developing wetlands into farmlands. Florida quickly formed a committee to consolidate grants to pay for any attempts, though the Civil War and Reconstruction halted progress until after 1877.
