国民党 (Guómíndǎng) is the Chinese name for the Kuomintang (KMT), a major political party that ruled mainland China from 1927 to 1949 and has since been a key opposition party in Taiwan. In historical contexts, it's often referred to as the Nationalist Party. The term carries strong historical and political connotations — you'll encounter it in discussions of the Chinese Civil War, cross-strait relations, and modern Taiwanese politics. It's a proper noun, not a generic term for 'nationalist party'.
