France's interest in Indochina in the nineteenth century grew out of its rivalry with Britain, which had excluded it from India and had effectively shut it out of other parts of mainland Southeast Asia. The French also desired to establish commerce in a region that promised so much untapped wealth and to redress the Vietnamese state's persecution of Catholic converts, whose welfare was a stated aim of French overseas policy. The Nguyen dynasty's repeated refusal to establish diplomatic relations and the violently anti-Christian policies of the emperors Minh Mang (1820- 41), Thieu Tri (1841-47), and Tu Duc (1848-83) impelled the French to engage in gunboat diplomacy that resulted, in 1862, in the establishment of French dominion over Saigon and over the three eastern provinces of the Cochinchina (Mekong Delta) region.

In the view of the government in Paris, Cambodia was a promising backwater. Persuaded by a missionary envoy to seek French protection against both the Thai and the Vietnamese, King Ang Duong invited a French diplomatic mission to visit his court. The Thai, however, pressured him to refuse to meet with the French when they finally arrived at Odongk in 1856. The much-publicized travels of the naturalist Henri Mouhot, who visited the Cambodian court, rediscovered the ruins at Angkor, and journeyed up the Mekong River to the Laotian kingdom of Luang Prabang from 1859 to 1861, piqued French interest in the kingdom's alleged vast riches and in the value of the Mekong as a gateway to China's southwestern provinces. In August 1863, the French concluded a treaty with Ang Duong's successor, Norodom (1859-1904). This agreement afforded the Cambodian monarch French protection (in the form of a French official called a résident--in French resident) in exchange for giving the French rights to explore and to exploit the kingdom's mineral and forest resources. Norodom's coronation, in 1864, was an awkward affair at which both French and Thai representatives officiated. Although the Thai attempted to thwart the expansion of French influence, their own influence over the monarch steadily dwindled. In 1867 the French concluded a treaty with the Thai that gave the latter control of Batdambang Province and of Siemreab Province in exchange for their renunciation of all claims of suzerainty over other parts of Cambodia. Loss of the northwestern provinces deeply upset Norodom, but he was beholden to the French for sending military aid to suppress a rebellion by a royal pretender.

In June 1884, the French governor of Cochinchina went to Phnom Penh, Norodom's capital, and demanded approval of a treaty with Paris that promised far-reaching changes such as the abolition of slavery, the institution of private land ownership, and the establishment of French résidents in provincial cities. Mindful of a French gunboat anchored in the river, the king reluctantly signed the agreement. Local elites opposed its provisions, however, especially the one dealing with slavery, and they fomented rebellions throughout the country during the following year. Though the rebellions were suppressed, an1cb and the treaty was ratified, passive resistance on the part of the Cambodians postponed implementation of the reforms it embodied until after Norodom's death.
