How Buddhist Thought Shapes Cambodia's Constitution, From the Monarchy to Citizenship Rights

A state religion, a restored monarchy and a test of rights

Cambodia's constitution places Buddhism at the centre of national identity while promising freedom of belief, protection for citizens and restraint in the use of state power. Adopted in 1993 after the Paris Peace Agreements, it restored the constitutional monarchy and gave legal recognition to religious institutions devastated under the Khmer Rouge.

Article 43 recognises Buddhism as the state religion. Article 68 supports Pali and Buddhist studies. The Supreme Patriarchs of the country's two principal Buddhist orders have a place in choosing a new monarch. Together, these arrangements connect the country's basic law to a religious tradition that has shaped Khmer society for centuries.

As of September 27, 2025, a recent amendment to Article 33 brings another part of that constitutional settlement into focus. It removed a prohibition on revoking citizenship and opened the way for legislation allowing nationality to be withdrawn in certain cases. Supporters describe the change as a defence of national interests. Critics warn of risks to political opponents and civil society where courts lack independence.

The debate touches a central expectation of Cambodia's Buddhist political tradition: rulers should exercise authority with compassion, restraint and concern for people's welfare. The constitution gives those expectations a place alongside the institutions of a modern state, including elected government, courts and a monarch intended to stand above party politics.

Understanding that relationship requires looking beyond the declaration of a state religion. Buddhist influence runs through national symbols, royal succession, education, community life and the ethical language used to judge government decisions. Its practical meaning depends on how officials, religious leaders and citizens put constitutional commitments into action.

From ancient kingdoms to the destruction of religious life

Buddhist teachings have influenced Khmer society since the Funan and Chenla periods. Early forms of the religion likely arrived through Indian maritime networks and later through neighbouring kingdoms. During the Angkor era, Mahayana Buddhism mixed with Brahmanic traditions and flourished under King Jayavarman VII.

Theravada Buddhism spread widely in the 13th century, with influence from Sri Lanka, and became the common faith of the population. The sangha, or community of monks, grew into a centre of village life. Temple compounds known as wats provided places for worship, schooling and community gatherings.

Ethical conduct, merit making and social harmony became part of everyday expectations as well as ideals of kingship. French colonial rule, the transition to independence and the brief era of Buddhist socialism after 1947 kept religion prominent in public affairs.

The Khmer Rouge violently broke that continuity during their rule in the 1970s. Monks were defrocked or killed, temples were destroyed and religious practice was banned. The assault nearly erased the institutions through which Buddhist learning and community life had been sustained.

Buddhism gradually returned after 1979. The peace process and restoration of constitutional government later gave that recovery a national legal framework. The main stages were:

• 1975: The destruction of the monastic order and suppression of religious life broke a long period of Buddhist involvement in society.
• After 1979: Buddhist practice and institutions gradually began to return.
• 1991: The peace accord helped prepare the way for a new constitutional settlement.
• 1993: The election and constitution restored the monarchy and affirmed Buddhism's place in the state.

The constitution's religious provisions therefore carried a meaning beyond ceremony. Recognition of Buddhism, support for religious education and the revival of royal institutions formed part of rebuilding a cultural order damaged by mass violence.

What the constitution says about religion

Article 4 places the relationship between people, faith and monarchy in the national motto. Cambodia's constitution states:

The national motto is Nation, Religion, King.

Article 43 gives Buddhism formal status as the state religion while upholding freedom of belief. Citizens of all faiths retain the right to worship and organise. The arrangement combines special recognition for the majority religion with constitutional protection for other religious communities.

Buddhist ideas also appear indirectly through the institutions and responsibilities the constitution supports. Religious learning, the monarchy's public role and the presence of senior monks in royal succession all preserve connections between faith and state authority.

Surveys across South and Southeast Asia indicate that most Cambodian Buddhists regard their faith as a core part of national identity. Many also say national laws should reflect Buddhist dharma, the teachings that guide moral conduct. Support for giving religious leaders a direct political role is much more limited.

That public preference helps explain the constitutional arrangement. Buddhism supplies a recognised source of ethical guidance and national belonging, while responsibility for everyday government rests with elected institutions. Monks occupy an important place in civic life without taking over the work of governing.

The King and the ideal of a righteous ruler

Theravada political thought includes the idea of the dhammaraja, a righteous ruler who governs according to dharma. Cambodia's constitution adapts that ideal to a modern monarchy by presenting the King as a source of unity, continuity and protection for the people.

Article 8 of the constitution describes the monarch's civic responsibilities in these terms:

The King is the symbol of national unity and the guarantor of national independence, sovereignty, and the rights and freedoms of citizens.

The language places ethical expectations on the throne. A monarch is expected to represent restraint, compassion and concern for the population, alongside the constitutional responsibilities attached to the office.

Norodom Sihanouk drew on Buddhist symbolism in public life and at times called himself a king monk. His example reflects the long connection between royal authority and religious ideals. The monarchy today remains a nonpartisan focal point intended to stand for national continuity rather than a particular political party.

Article 13 establishes a Council of the Throne to choose a new King when the throne becomes vacant. By law, its members include the Supreme Patriarchs of the two principal Buddhist orders alongside senior state officials. Royal heirs often spend time ordained in a monastery as part of their formation.

Senior monks therefore have a formal role at a decisive moment in the monarchy's life. Their presence connects succession to the expectation that a future King should be grounded in Buddhist ethics, while the council also includes representatives of state institutions.

How the state and the sangha share public space

Cambodia's monastic community has two principal orders: the larger Maha Nikaya and the Dhammayuttika Nikaya. Each has its own hierarchy. The Ministry of Cults and Religion works with monastic leaders to maintain order within the clergy, giving the state a coordinating role in religious administration.

Monks are citizens and can vote, although clerical codes discourage partisan activism. Their public position combines civic rights with expectations of spiritual discipline and political restraint.

The sangha can confer legitimacy on rulers who uphold moral standards and provide a corrective voice when leaders depart from Buddhist principles. Its influence operates within a relationship in which the state also regulates religious institutions. Monastic leaders must navigate between moral authority and political neutrality.

Across South and Southeast Asia, states with Buddhist majorities organise that relationship differently. Some centralise control of the monastic hierarchy to maintain uniformity. Others allow religious orders considerable autonomy and take a lighter administrative role. Both arrangements face difficulties when popular religious movements challenge official structures or when internal disputes arise without a single authority to settle them.

Cambodia combines elements of these approaches. The ministry cooperates with monastic leaders, Buddhism has constitutional recognition and the Supreme Patriarchs participate in royal succession. The sangha also remains a distinct moral community able to express expectations about the conduct of rulers.

Why Buddhist education has constitutional protection

Article 68 directs the state to promote Buddhist studies and safeguard religious institutions. It recognises Pali schools and monastic education, preserving a tradition in which temples taught literacy as well as ethics.

Pali and Buddhist studies help sustain religious learning and a trained clergy. Their constitutional recognition also reflects the historic role of the sangha in passing knowledge between generations and providing instruction within local communities.

Cambodia's national education system is largely secular in curriculum and structure. Buddhist concepts nevertheless remain present in civic education and cultural instruction. The Middle Path, for example, encourages moderation and discourages extremes, providing an ethical basis for approaches that favour social cohesion and gradual reform over confrontation.

The education sector has been rebuilt since the 1980s with substantial involvement from international partners. Inclusion policies seek to address gaps affecting girls and women, ethnic minorities and rural communities. Resource limits, teacher shortages and governance problems continue to constrain progress.

Religious institutions complement public schools through moral teaching and community service. Their contribution preserves Buddhist educational traditions alongside the delivery of the national curriculum, rather than making all schooling religious.

Compassion, human dignity and limits on force

Article 46 prohibits human trafficking and the exploitation of prostitution. Article 54 bans nuclear, chemical and biological weapons. These provisions connect the protection of vulnerable people and limits on destructive force with values of compassion and the avoidance of harm.

The Noble Eightfold Path, particularly Right Livelihood and Right Action, supplies an ethical vocabulary for thinking about law and public policy even where the constitution does not cite a specific doctrine. In accessible terms, these ideas concern earning a living and acting in ways guided by ethical conduct.

Equal treatment, freedom of belief and respect for human dignity also sit comfortably within this Buddhist moral outlook. The constitution expresses these commitments through legal rights and duties that apply to public institutions and citizens.

Cambodia's constitution guarantees civil rights and due process, meaning the legal procedures intended to ensure that people receive fair treatment. Independent assessments describe a judiciary influenced by the executive and pressure on civil society. For citizens seeking protection, the practical issue is whether courts and other institutions can enforce the rights written into the constitution.

Buddhist expectations of moral restraint apply to the use of legally granted power as well as to personal conduct. Legal reforms, professional courts and active civic education are therefore central to making constitutional commitments effective in daily life.

Faith in villages and a changing generation

Wats remain centres for ceremonies, ethical teaching and community welfare. Their role connects the constitutional recognition of Buddhism with places where people gather, maintain family traditions and find social support.

Younger Cambodians face different routines from those of their parents. Study, work and digital life take up much of their time, and some participate less in traditional religious activities. Religious schools and pagodas are responding through social media outreach and new teaching formats.

Motivations for religious involvement vary. Some people seek to preserve family traditions, while others look for moral guidance or social connection. Practice is being adjusted to modern routines, with Buddhism retaining its constitutional position as a national anchor.

Neutrality and the use of Buddhist diplomacy

Chapter IV of the constitution sets out a foreign policy of neutrality, friendly relations and peaceful coexistence. These commitments match Buddhist teachings on nonviolence and compassion for all peoples, while serving a small country situated among larger powers.

Neutrality also reflects the goal of avoiding entanglement in foreign conflicts. The constitutional preference for cooperation connects the country's external relations with the ethical language used in domestic public life.

Buddhist heritage provides another channel for diplomacy, particularly with India, where Buddhism originated even though the population today is majority Hindu. Leaders in both countries have used religious symbols, sites and exchanges to build goodwill.

Pilgrimages, restoration projects and the construction of monasteries in India in Cambodian architectural styles keep those cultural connections active. They support relationships through shared heritage alongside the constitution's call for peaceful international conduct.

Citizenship changes put restraint under scrutiny

The recent amendment to Article 33 removed a previous constitutional prohibition on revoking citizenship. It opened the door to legislation that could strip people of nationality in certain cases, bringing national security arguments into direct contact with protections for individual dignity.

Supporters present the change as a means of protecting national interests and loyalty. Prime Minister Hun Manet described the intended targets as people who:

oppose the interest of the country, conspire with foreign powers, or plot to destroy the country.

Critics warn that broad criteria, combined with weak judicial independence, could allow the measures to be used against political opponents or civil society voices. The exact date of the amendment and a timetable for implementation were not given.

The practical debate concerns how the new powers will be defined and applied. A constitutional order shaped by Buddhist ethics places expectations of restraint on rulers and concern for the welfare of all citizens, including those who dissent.

Protection against arbitrary punishment, fair legal procedures and respect for personal dignity are central to that expectation. The citizenship change brings into focus the continuing task of making national security policy work alongside the compassion and nonviolence affirmed in Cambodia's constitutional culture.
