State religion

A state religion (also called official religion) is a religion or creed officially endorsed by a sovereign state. A state with an official religion (also known as confessional state), while not a secular state, is not necessarily a theocracy. State religions are official or government-sanctioned establishments of a religion, where public spending on the maintenance of church property and clergy is unrestricted, but the state does not need to be under the legislative control of the clergy as it would be in a theocracy.
Official religions have been known throughout human history in almost all types of cultures, reaching into the Ancient Near East and prehistory. The relation of religious cult and the state was discussed by the ancient Latin scholar Marcus Terentius Varro, under the term of theologia civilis (lit. 'civic theology'). The first state-sponsored Christian denomination was the Armenian Apostolic Church, established in 301 CE. In Christianity, as the term church is typically applied to a place of worship for Christians or organizations incorporating such ones, the term state church is associated with Christianity as sanctioned by the government, historically the state church of the Roman Empire in the last centuries of the Empire's existence, and is sometimes used to denote a specific modern national branch of Christianity. Closely related to state churches are ecclesiae, which are similar but carry a more minor connotation.
In the Middle East, the majority of states with a predominantly Muslim population have Islam as their official religion, though the degree of religious restrictions on citizens' everyday lives varies by country. Rulers of Saudi Arabia use religious power, while Iran's secular presidents are supposed to follow the decisions of religious authorities since the 1979 Islamic Revolution. Turkey, which also has Muslim-majority population, became a secular country after Atatürk's Reforms, although unlike the Russian Revolution of the same time period, it did not result in the adoption of state atheism.
The degree to which an official national religion is imposed upon citizens by the state in contemporary society varies considerably; from high as in Saudi Arabia and Iran, to none at all as in Greenland, Denmark, England, Iceland, and Greece (in Europe, the state religion might be called in English, the established church).
The degree and nature of state backing for denomination or creed designated as a state religion can vary. It can range from mere endorsement (with or without financial support) with freedom for other faiths to practice, to prohibiting any competing religious body from operating and to persecuting the followers of other sects. In Europe, competition between Catholic and Protestant denominations for state sponsorship in the 16th century evolved the principle Cuius regio, eius religio (states follow the religion of the ruler) embodied in the text of the treaty that marked the Peace of Augsburg in 1555. In England, Henry VIII broke with Rome in 1534, being declared the Supreme Head of the Church of England, the official religion of England continued to be "Catholicism without the Pope" until after his death in 1547.
In some cases, an administrative region may sponsor and fund a set of religious denominations; such is the case in Alsace-Moselle in France under its local law, following the pre-1905 French concordatory legal system and patterns in Germany.
A state church (or "established church") is a state religion established by a state for use exclusively by that state. In the case of a state church, the state has absolute control over the church, but in the case of a state religion, the church is ruled by an exterior body; for example, in the case of Catholicism, the Vatican has control over the church.
Disestablishment is the process of repealing a church's status as an organ of the state. In a state where an established church is in place, opposition to such a move may be described as antidisestablishmentarianism.

Jurisdictions where a Lutheran church has been fully or partially established as a state recognized religion include the Nordic States.
Jurisdictions that give various degrees of recognition in their constitutions to Lutheranism without establishing it as the state religion:
Many Muslim-majority countries have constitutionally established Islam, or a specific form of it, as a state religion. Proselytism (converting people away from Islam) is often illegal in such states.
In some countries, Islam is not recognized as a state religion, but holds special status:
In some countries, there is a political ideology sponsored by the government that may be called political religion.
Islam in Russia is recognized under the law and by Russian political leaders as one of Russia's traditional religions, Islam is a part of Russian historical heritage, and is subsidized by the Russian government. The position of Islam as a major Russian religion, alongside Orthodox Christianity, dates from the time of Catherine the Great, who sponsored Islamic clerics and scholarship through the Orenburg Assembly.
In addition, the Treaty of Lausanne explicitly guarantees the security and protection of both Greek and Armenian Orthodox Christian minorities and the Turkish-Jews. Their religious institutions are recognized officially by the state.
Catholic Christianity, as opposed to Arianism and other ideologies deemed heretical, was declared to be the state religion of the Roman Empire on 27 February 380 by the decree De fide catolica of Emperor Theodosius I.
In China, the Han dynasty (206 BCE – 220 CE) advocated Confucianism as the de facto state religion, establishing tests based on Confucian texts as an entrance requirement into government service—although, in fact, the "Confucianism" advocated by the Han emperors may be more properly termed a sort of Confucian Legalism or "State Confucianism". This sort of Confucianism continued to be regarded by the emperors, with a few notable exceptions, as a form of state religion from this time until the collapse of the Chinese monarchy in 1912. Note, however, there is a debate over whether Confucianism (including Neo-Confucianism) is a religion or purely a philosophical system.
During the Mongol-led Yuan dynasty of China (1271–1368 CE), Tibetan Buddhism was established as the de facto state religion by the Kublai Khan, the founder of the Yuan dynasty. The top-level department and government agency known as the Bureau of Buddhist and Tibetan Affairs (Xuanzheng Yuan) was set up in Khanbaliq (modern Beijing) to supervise Buddhist monks throughout the empire. Since Kublai Khan only esteemed the Sakya sect of Tibetan Buddhism, other religions became less important. Before the end of the Yuan dynasty, 14 leaders of the Sakya sect had held the post of Imperial Preceptor (Dishi), thereby enjoying special power.
The Mongol rulers Ghazan of Ilkhanate and Uzbeg of Golden Horde converted to Islam in 1295 CE because of the Muslim Mongol emir Nawruz and in 1313 CE because of Sufi Bukharan sayyid and sheikh Ibn Abdul Hamid respectively. Their official favoring of Islam as the state religion coincided with a marked attempt to bring the regime closer to the non-Mongol majority of the regions they ruled. In Ilkhanate, Christian and Jewish subjects lost their equal status with Muslims and again had to pay the poll tax; Buddhists had the starker choice of conversion or expulsion.
The list of former confessional states only includes states that abolished their state religion themselves, not states with a state religion that were conquered, fell apart or otherwise disappeared.
