During this time period, the federal government and other institutions created loyalty programs. To keep their jobs, or to be hired, employees had to swear an oath of loyalty to the Constitution and to swear that they had never been a part of an organization that had advocated the overthrow of the government.

Under President Truman the first loyalty program was started in 1947 - affecting federal employees and potential employees. The program soon spread to other organizations, particularly state governments, schools, and universities.
