The Claremont Institute is a prominent American conservative think tank founded in 1979 and based in Upland, California. Established by students of political philosopher Harry V. Jaffa, the Institute focuses on promoting the principles of the American Founding and the application of natural law to contemporary politics and culture. Its core mission is to restore these foundational principles through extensive research, educational programs, and influential publications, including the Claremont Review of Books and The American Mind. Serving as a significant intellectual hub for conservative thought, the Institute engages with academics, policymakers, and the public to shape discourse on constitutionalism, American exceptionalism, and critiques of progressive ideologies. In recent years, the Claremont Institute has become particularly known for its embrace and intellectual defense of Trump-era ideologies, often aligning with the national conservatism movement. Its fellows and publications have played a notable role in articulating and promoting these perspectives, influencing a segment of the conservative political landscape. The Institute has also faced scrutiny and controversy due to the involvement of some of its senior fellows in politically charged events, particularly concerning the 2020 U.S. presidential election.
