noun which may take the genitive case particle 'no', noun
under the command of; under the banner of; influenced by
Literary or formal term for being under someone's leadership, influence, or banner. Often used in historical, political, or organizational contexts. The 'influenced by' sense is an extension of the command metaphor.

その政治家は大統領の麾下で政策を推進した。
The politician advanced policies under the banner of the president.

傘下 is more common in modern business contexts (e.g., under the umbrella of a company), while 麾下 has a stronger military or leadership connotation and is more literary.
配下 refers to subordinates or people under one's direct control, focusing on the hierarchical relationship, whereas 麾下 emphasizes being under the command or influence of a superior.
From Chinese 麾下 (huīxià), literally 'under the banner/flag', where 麾 means 'banner' or 'command flag' and 下 means 'under'. The term entered Japanese with the same meaning, retaining its literary and formal tone.
