Samuel P. Huntington, American political scientist, author, and academic (d. 2008)
Samuel Phillips Huntington (April 18, 1927 – December 24, 2008) was an American political scientist, adviser, and academic. He spent more than half a century at Harvard University, where he was director of Harvard's Center for International Affairs and the Albert J. Weatherhead III University Professor.

During the presidency of Jimmy Carter, Huntington was the White House Coordinator of Security Planning for the National Security Council. During the 1980s Apartheid era in South Africa, he served as an adviser to P. W. Botha's Security Services.

He is best known for his 1993 theory, the "Clash of Civilizations", of a post-Cold War new world order. He argued that future wars would be fought not between countries, but between cultures, and that Islamic extremism would become the biggest threat to Western domination of the world. Huntington is credited with helping to shape American views on civilian-military relations, political development, and comparative government. According to the Open Syllabus Project, Huntington is the second most frequently cited author on college syllabi for political science courses.
