The Sentinels were particularly concerned with protecting the rights of the States, limiting government's interference with and regulation of business, and combating the threat of international communism.
[2] In 1924-1925 the Sentinels garnered national attention when, under the leadership of Louis A. Coolidge, they successfully swayed Massachusetts opinion against the Child Labor Act.
They persuaded key Massachusetts constituents to oppose the Child Labor Act by convincing them that it had Bolshevistic origins, and that it would lead to extreme consequences; e.g. denying a teenager of the right to help his widowed mother support his siblings, or even to assist with household and farm chores.
[6] The Sentinels held annual meetings during this period, at each of which they adopted a "program of policies" which were then disseminated in pamphlet form to stir public opinion.
[6] In 1934, under the coordination of national chairman Raymond Pitcairn, the Sentinels conducted a large-scale campaign against a proposed tax law that would have required publication of personal financial data, including an individual's gross income.
They distributed hundreds of thousands of protest stickers and form letters urging people to demand that Congress repeal what they described as an "outrageous invasion of privacy."
[22] Substantiating these allegations, the Black Commission, a 1936 U.S. Senate investigation into lobbying, discovered instances of antisemitic language and attitudes within the Sentinels.
"[25] However, these statements failed to erase the damage done to the reputation of the American Liberty League (the parent organization of the Sentinels) by the findings of the Black investigation.
[21] The organization donated the remainder of its funds to Williams College for the purpose of endowing the Sentinels of the Republic Advanced Study Prize, a yearly award for the best student essay on the U.S.
[21] The Sentinels also donated a collection of primary documents (brochures, newsletters, minutes) to the college's archives, where they currently reside, for the purpose of aiding students in preparing their essays.
