noun
hegemonism
Political term for a doctrine or policy of seeking dominance or hegemony, often used in international relations contexts.
覇権主義は国際社会の安定を脅かす。
Hegemonism threatens the stability of the international community.
覇権 means 'hegemony' or 'supremacy' itself, while 覇権主義 refers to the ideology or policy of pursuing such dominance.
Compound of 覇権 (hegemony) + 主義 (doctrine, -ism). The exact historical derivation is uncertain, but the term follows the pattern of modern political -isms.
