A French gunboat forced the King of Cambodia to sign

In 1884, the French governor Charles Thomson forced King Norodom of Cambodia to sign a treaty of reinforced guardianship. Dissatisfied with the functioning of the protectorate, the governor went directly to the royal palace of Phnom Penh escorted by armed troops and a gunboat. Cornered to save his throne, the monarch gave in and agreed to entrust the control of customs duties to France.
