"중앙강국" (Central Power) refers to a historical term used primarily during the First World War to describe the alliance of Germany, Austria-Hungary, the Ottoman Empire, and Bulgaria. These nations opposed the Allied Powers, which included countries like France, Britain, and Russia. The Central Powers aimed to expand their influence and territory through military means. The term also highlights the geopolitical significance of central nations in a region, often acting as key players in international relations. In modern contexts, it can refer to countries that hold substantial power and influence within a specific area, shaping regional dynamics and policies.
