The Popular Health Movement of the 1830s–1850s was an aspect of Jacksonian-era politics and society in the United States. The movement promoted a rational skepticism toward claims of medical expertise that were based on personal authority, and encouraged ordinary people to understand the pragmatics of health care.[1] Arising in the spirit of Andrew Jackson's anti-elitist views,[2] the movement succeeded in ending almost all government regulation of health care. During the first two decades of the 19th century, states had regularly enacted licensing legislation; by 1845, only three states still licensed medical doctors.[3] Among the leading figures within the movement were Samuel Thomson and Sylvester Graham.[4]
