Definition

1. Noun (Historical/Political Term):
   • Vassal state: A country or state that is subordinate to a more powerful state, often required to pay tribute and provide military support in exchange for protection and a degree of autonomy. This term is primarily used in historical contexts, especially regarding East Asian tributary systems.

Usage Examples

• Noun:
  • Trong hệ thống triều cống, nhiều nước láng giềng trở thành phiên quốc của Trung Hoa. (Within the tributary system, many neighboring countries became vassal states of China.)
  • Sử sách ghi chép về các phiên quốc thường xuyên cử sứ thần đến kinh đô. (Historical records note that vassal states regularly sent envoys to the capital.)

Advanced Usage

Variants and Related Words

• Chư hầu (n): Another historical term for "vassal" or "feudal lord," sometimes used in a similar context but can imply a more feudal relationship within a single cultural sphere.
• Nước chư hầu (n): Vassal state (a more common compound phrase; the target word is its direct synonym).

Synonyms

• Nước bảo hộ: Protectorate (implies a different, often more direct form of control).

Notes on Meaning
