protectorate; dependency; dependent state
A political term for a country or territory that is under the protection and partial control of a stronger state, while retaining some internal autonomy.
Former protectorates were under the strong influence of the suzerain state.
Under international law, a protectorate may not be considered an independent state.
保護国 is a more general term for a protectorate, while 被保護国 emphasizes the passive aspect of being protected, often used in historical or legal contexts.
植民地 (colony) implies direct control and settlement by the ruling power, whereas 被保護国 retains a degree of formal sovereignty and local governance.
Compound of 被 (hi, 'receiving') + 保護 (hogo, 'protection') + 国 (koku, 'country'), literally 'country receiving protection'. The term is a modern political coinage, likely influenced by Western concepts of protectorates.
