Secular state
A secular state is an idea pertaining to secularity, whereby a state is or purports to be officially neutral in matters of religion, supporting neither religion nor irreligion. A secular state claims to treat all its citizens equally regardless of religion, and claims to avoid preferential treatment for a citizen based on their religious beliefs, affiliation or lack of either over those with other profiles. Although secular states have no state religion, the absence of an established state religion does not mean that a state is completely secular or egalitarian. For example, some states that describe themselves as secular have religious references in their national anthems and flags, or laws that benefit one religion or another. Origin and practice
Secularity can be established at a state's creation (e.g., the Soviet Union, the United States) or by it later secularizing (e.g., France or Nepal). Movements for laïcité in France and separation of church and state in the United States have defined modern concepts of secularism, the United States of America being the first explicitly secular government in history. Historically, the process of secularisation typically involves granting religious freedom, disestablishing state religions, stopping public funds being used for religion, freeing the legal system from religious control, freeing up the education system, tolerating citizens who change religion or abstain from religion, and allowing political leaders to come to power regardless of their religious beliefs. In France, Italy, and Spain, for example, official holidays for the public administration tend to be Christian feast days. Any private school in France that contracts with Éducation nationale means its teachers are salaried by the state—most of the Catholic schools are in this situation and, because of history, they are the majority; however, any other religious or non-religious schools also contract this way. In some European states where secularism confronts monoculturalist philanthropy, some of the main Christian sects and sects of other religions depend on the state for some of the financial resources for their religious charities. It is common in corporate law and charity law to prohibit organized religion from using those funds to organize religious worship in a separate place of worship or for conversion; the religious body itself must provide the religious content, educated clergy and laypersons to exercise its own functions and may choose to devote part of their time to the separate charities. To that effect, some of those charities establish secular organizations that manage part of or all of the donations from the main religious bodies. Many states that are nowadays secular in practice may have legal vestiges of an earlier established religion. Secularism also has various guises that may coincide with some degree of official religiosity. In the United Kingdom, the head of state is still required to take the Coronation Oath enacted in 1688, swearing to maintain the Protestant Reformed religion and to preserve the established Church of England. The UK also maintains seats in the House of Lords for 26 senior clergymen of the Church of England, known as the Lords Spiritual. In Canada the Canadian Charter of Rights and Freedoms affords secular freedoms of conscience and religion, thought, belief, opinion and expression, including communication, assembly and association yet the Charter's preamble maintains the concept of "the supremacy of God" which would appear to disadvantage those who hold nontheistic or polytheistic beliefs, including atheism and Buddhism. Italy has been a secular state since the enactment of the Constitution in 1948 (stressed by a Constitutional court's decision in 1985), but still recognizes a special status for the Catholic Church. The reverse progression can also occur, however; a state can go from being secular to being a religious state, as in the case of Iran where the secularized Imperial State of Iran was replaced by an Islamic Republic. Nonetheless, the last 250 years has seen a trend towards secularism. List of secular states by continent

Formerly secular states
  (1972–1977)

  Democratic Republic of Afghanistan (1978–1987)
 Afghanistan became a secular state following the Saur Revolution however Sunni Islam was briefly reinstated as the state religion under General Secretary Hafizullah Amin until his assassination in December 1979. President Mohammad Najibullah would reinstate Sunni Islam as the state religion in 1987. People's Republic of Kampuchea (1979-1993)
 Kampuchea was a secular state from 1979 until the restoration of its monarchy in 1993. Imperial State of Iran (1925–1979)
 Iran became a secular state following the 1921 Persian coup d'état with the establishment of the Pahlavi dynasty as the ruling house of the country in 1925, until the Islamic Revolution in 1979. (1932–1993)
 Iraq became a secular state in 1932 after its independence. However, the Ba'athist regime led by Saddam Hussein launched the Return to Faith campaign in 1993 and placed significant emphasis on Islam within all sectors of state and public life. Myanmar (formerly Burma) (1885–1961; 1962–2008)
 Myanmar was a secular state during the colonial period and post-independence period until 1961 and again under the socialist regime, and the military regime until 2008. (1962–2017)
 In 2017, the Samoan legislative assembly approved a constitutional amendment that instituted Christianity as the state religion. Ambiguous countries
 
 There is constitutional ambiguity whether Bangladesh is a secular country or an Islamic country. In 2010, the high court of Bangladesh reinstated secularism as a part of the Bangladesh constitution after terming the 1977 constitutional amendment done by then Bangladesh President Ziaur Rahman as illegal. Political leaders, and experts have expressed uncertainty; if Bangladesh is a secular state or an Islamic state. See also
