A secular religion is a nontheistic communal belief system.
 Among systems that have been characterized as secular religions are capitalism, communism, nationalism, Auguste Comte's Religion of Humanity, and the Cult of Reason that developed after the French Revolution.
Nationalism is a range of political, social, and economic systems characterized by promoting the interests of a particular nation, particularly with the aim of gaining and maintaining self-governance, or full sovereignty, over the group's homeland.
 The political ideology therefore holds that a nation should govern itself, free from unwanted outside interference, and is linked to the concept of self-determination.
 Nationalism is further oriented towards developing and maintaining a national identity based on shared characteristics such as culture, language, race, religion, political goals or a belief in a common ancestry.
 Nationalism therefore seeks to preserve the nation's culture.
 It often also involves a sense of pride in the nation's achievements, and is closely linked to the concept of patriotism.
 In some cases, nationalism referred to the belief that a nation should be able to control the government and all means of production.
Coptic nationalism refers to the nationalism of Copts (Coptic: "Niremenkīmi Enkhristianos ", Egyptian Arabic: أقباط‎ ‎ "Aqbat "), an ethno-religious group that primarily inhabit the area of modern Egypt, where they are the largest Christian denomination.
The Akha people migrated from Tibet to the mountainous region of Laos, China, Burma and Thailand.
 The Akha Villages traditionally practice Akhazah, which is a religious as well as cultural belief system.
 Ahkazah is an animistic belief system with various rituals, festivals and spirits that permeate everyday life.
Sinhalese Buddhist nationalism is a political ideology which combines a focus upon Sinhalese culture and ethnicity with an emphasis upon Theravada Buddhism, which is the majority belief system of most of the Sinhalese in Sri Lanka.
 It mostly originated in reaction to the colonisation of Sri Lanka by the British Empire, blatant discrimination against Sinhala Buddhists while favouring ethnic and religious minorities, and became increasingly assertive in the years following the independence of the country.
A parody religion or mock religion is a belief system that challenges spiritual convictions of others, often through humor, satire, or burlesque (literary ridicule).
 Often created to achieve a specific purpose related to another belief system, a parody religion can be a parody of several religions, sects, gurus, cults, or new religious movements at the same time or even a parody of no particular religion, instead parodying the concept of religious belief itself.
 In some parody religions, emphasis is on having fun and being a convenient excuse for pleasant social interaction among the like-minded (e.g., the Church of the SubGenius).
 Other parody religions target a specific religion, sect, cult, or new religious movement.
Proto-Indo-European religion is the belief system adhered to by the Proto-Indo-Europeans.
 Although this belief system is not directly attested, it has been reconstructed by scholars of comparative mythology based on the similarities in the belief systems of various Indo-European peoples.
Territorial nationalism describes a form of nationalism based on the belief that all inhabitants of a particular nation owe allegiance to their country of birth or adoption.
 According to territorial nationalism every individual must belong to a nation, but can choose which one to join.

 Citizenship is idealized by a territorial nationalist.
 A criterion of a territorial nationalism is the establishment of a mass, public culture based on common values and traditions of the population.
 Legal equality is essential for territorial nationalism.
The Copts (Coptic: "Niremenkīmi Enkhristianos ", Egyptian Arabic: أقباط‎ ‎ "Aqbat ") are an ethno-religious group that primarily inhabit the area of modern Egypt, where they are the largest Christian denomination.
 Copts are also the largest Christian adherent group in Sudan and Libya.
 Historically, they spoke the Coptic language, a direct descendant of the Demotic Egyptian that was spoken during the Roman era.
 The Coptic language is a focus of Coptology and remains in liturgical use, although most Copts today speak Arabic.
Deprogramming refers to measures that claim to assist a person who holds a controversial belief system in changing those beliefs and abandon allegiance to the religious, political, economic, or social group associated with the belief system.
 The dictionary definition of deprogramming is "to free" or "to retrain" someone from specific beliefs, some controversial methods and practices of self-identified "deprogrammers" have involved kidnapping, false imprisonment, and coercion, which have sometimes resulted in criminal convictions of the deprogrammers.
 Some deprogramming regimens are designed for individuals taken against their will, which has led to controversies over freedom of religion, kidnapping, and civil rights, as well as the violence which is sometimes involved.
