The "Clash of Civilizations" thesis was introduced by American political scientist Samuel P. Huntington in a 1993 Foreign Affairs article and expanded in his 1996 book The Clash of Civilizations and the Remaking of World Order. Huntington argued that, with the end of the Cold War, the fundamental source of conflict in the new era would not be primarily ideological or economic, but cultural. He grouped the world into several major civilizations — typically listed as Western, Orthodox, Islamic, Sinic (Confucian), Hindu, Japanese, Latin American, Buddhist, and African — and predicted that the most dangerous fault lines would run between them, especially along the borders of the Islamic world.
Key claims include:
- Civilizational identity (language, religion, history, customs) will increasingly shape alliances and antagonisms.
- The West's relative power is declining vis-à-vis non-Western civilizations, particularly Sinic and Islamic.
- "Fault line" conflicts — such as those in the Balkans, the Caucasus, or Kashmir — exemplify civilizational friction.
- The West should consolidate internally and avoid attempts to universalize its values, which Huntington saw as provocative.
The thesis has been highly influential but heavily contested. Critics including Edward Said ("The Clash of Ignorance," 2001) argued it essentializes civilizations as monolithic and ignores internal pluralism and shared history. Amartya Sen, in Identity and Violence (2006), challenged the reduction of individuals to a single civilizational identity. Empirical studies have found that most armed conflicts since 1989 have occurred within civilizations rather than between them.
The argument gained renewed attention after the September 11, 2001 attacks, when commentators invoked it to frame relations between the West and the Muslim world — a framing Huntington himself had cautioned was about civilizational politics, not a literal war of religions. It remains a touchstone in debates over identity, secularism, and the structure of post-Cold War order.
Example
After the September 11, 2001 attacks, policy commentators frequently cited Huntington's "Clash of Civilizations" thesis to interpret U.S. relations with the Muslim world.
