Khmer nationalism or Cambodian nationalism (Khmer: ជាតិនិយម) is a form of nationalism found in Cambodia, which asserts that Cambodians are a nation and that promotes the cultural unity of the Cambodian people.
Another division in the Cambodian sangha can be seen in what has been called the "young monks" movement, a small group of politically active monks (primarily Maha Nikaya) voicing public opposition to the current government. The "young monks" are primarily junior members of the clergy, drawn from temples in and around Phnom Penh. Unlike the Engaged modernists, their interest is not in using the authority of the sangha to aide social development programs, but rather to express direct opposition to government policies and corruption. Since the 1993 UN-monitored elections, monks have been permitted to vote in Cambodia (a move opposed by some senior monks). While this has not resulted in any large-scale mobilization of the sangha as a political force, it has drawn some young monks farther into participation in parliamentary politics. Many of these young monks are associated with opposition figure Sam Rainsy and his political party, the SRP.
Members of the young monks movement have participated in and organized public demonstrations in Phnom Penh, aimed at drawing attention to perceived government misdeeds. The Maha Nikaya hierarchy has condemned this form of political activism, calling for the arrest of some monks and defrocking others.
Unlike in Vietnam, Cambodian nationalism remained relatively quiet during much of French rule mostly due to lesser education influence, which helped literacy rates remain low and prevented nationalist movements like those taking place in Vietnam. However, among the French-educated Cambodian elite, the Western ideas of democracy and self-rule as well as French restoration of monuments such as Angkor Wat created a sense of pride and awareness of Cambodia's once powerful status in the past. In education, there was also growing resentment among Cambodian students of the minority Vietnamese holding a more favored status. In 1936, Son Ngoc Than and Pach Choeun began publishing Nagaravatta (Notre cité) as a French language anti-colonial and at times, anti-Vietnamese newspaper. Minor independence movements, especially the Khmer Issarak, began to develop in 1940 among Cambodians in Thailand, who feared that their actions would have led to punishment if they had operated in their homeland.
