Colonization had profound and lasting effects on Cambodia. The country experienced successive periods of colonization, primarily by the French and briefly by the Japanese during World War II. Under French colonial rule from the mid-19th century until the mid-20th century, Cambodia underwent significant changes. The French imposed their administrative structure, education system, and legal framework, which altered traditional Khmer governance and society. The monarchy was retained but became a figurehead, with real power held by the French colonial administration.
Economically, Cambodia was integrated into the French Indochina colony, with its resources exploited for the benefit of the colonial power. This led to economic disparities and social inequalities. Culturally, the French influence left a mark on Cambodian architecture, cuisine, and education, with the introduction of the French language and culture. Colonization also had a lasting impact on Cambodia's political landscape. After gaining independence from France in 1953, Cambodia faced political instability, including the rise of the Khmer Rouge. The latter's brutal regime, supported by neighboring Vietnam, led to genocide and widespread suffering during the late 1970s.
