In sociology, secularization (or secularisation) is the transformation of a society from close identification with religious values and institutions toward non-religious values and secular institutions. The secularization thesis expresses the idea that as societies progress, particularly through modernization, rationalization, and advances in science and technology, religious authority diminishes in all aspects of social life and governance. In recent years, the secularization thesis has been challenged due to some global studies indicating that the irreligious population of the world may be in decline as a percentage of the world population due to irreligious countries having subreplacement fertility rates and religious countries having higher birth rates in general. Christian sociologist Peter L. Berger coined the term desecularization to describe this phenomenon. In addition, secularization rates are stalling or reversing in some countries/regions such as the countries in the former Soviet Union or large cities in the Western World with significant amounts of religious immigrants.
As a second meaning, the term "secularization" may also occur in the context of the lifting of monastic restrictions from a member of the clergy.
Secularization, in the main, sociological meaning of the term, involves the historical process in which religion loses social and cultural significance. As a result of secularization the role of religion in modern societies becomes restricted. In secularized societies faith lacks cultural authority, and religious organizations have little social power.
Secularization has many levels of meaning, both as a theory and as a historical process. Social theorists such as Karl Marx (1818–1883), Sigmund Freud (1856–1939), Max Weber (1864–1920), and Émile Durkheim (1858–1917) postulated that the modernization of society would include a decline in levels of religiosity. Study of this process seeks to determine the manner in which, or extent to which religious creeds, practices, and institutions are losing social significance. Some theorists argue that the secularization of modern civilization partly results from our inability to adapt the broad ethical and spiritual needs of mankind to the increasingly fast advance of the physical sciences.
In contrast to the "modernization" thesis, Christian Smith and others argue that intellectual and cultural élites promote secularization to enhance their own status and influence. Smith believes that intellectuals have an inherent tendency to be hostile to their native cultures, causing them to embrace secularism.
The term "secularization" also has additional meanings, primarily historical and religious. Applied to church property, historically it refers to the seizure of church lands and buildings, such as Henry VIII's 16th-century dissolution of the monasteries in England and the later acts during the 18th-century French Revolution, as well as by various anti-clerical enlightened absolutist European governments during the 18th and 19th centuries, which resulted in the expulsion and suppression of the religious communities which occupied them. The 19th-century Kulturkampf in Germany and Switzerland and similar events in many other countries also were expressions of secularization.
Still another form of secularization refers to the act of Prince-Bishops or holders of a position in a Monastic or Military Order - holding a combined religious and secular authority under the Catholic Church - who broke away and made themselves into completely secular (typically, Protestant) hereditary rulers. For example, Gotthard Kettler (1517–1587), the last Master of the Livonian Order, converted to Lutheranism, secularised (and took to himself) the lands of Semigallia and Courland which he had held on behalf of the order - which enabled him to marry and leave to his descendants the Duchy of Courland and Semigallia.
The 1960s saw a trend toward increasing secularization in Western Europe, North America, Australia, and New Zealand. This transformation accompanied major social factors: economic prosperity, youth rebelling against the rules and conventions of society, sexual revolution, women's liberation, radical theology, and radical politics.
Secularization is sometimes credited both to the cultural shifts in society following the emergence of rationality and the development of science as a substitute for superstition—Max Weber called this process the "disenchantment of the world"—and to the changes made by religious institutions to compensate. At the most basic stages, this begins with a slow transition from oral traditions to a writing culture that diffuses knowledge. This first reduces the authority of clerics as the custodians of revealed knowledge. The shift of responsibility for education from the family and community to the state has had two consequences:
A major issue in the study of secularization is the extent to which certain trends such as decreased attendance at places of worship indicate a decrease in religiosity or simply a privatization of religious belief, where religious beliefs no longer play a dominant role in public life or in other aspects of decision making.
C. John Sommerville (1998) outlined six uses of the term secularization in the scientific literature. The first five are more along the lines of 'definitions' while the sixth is more of a 'clarification of use':
Abdel Wahab Elmessiri (2002) outlined two meanings of the term secularization:
As studied by sociologists, one of the major themes of secularization is that of "differentiation"—i.e., the tendency for areas of life to become more distinct and specialized as a society becomes modernized. European sociology, influenced by anthropology, was interested in the process of change from the so-called primitive societies to increasingly advanced societies. In the United States, the emphasis was initially on change as an aspect of progress, but Talcott Parsons refocused on society as a system immersed in a constant process of increased differentiation, which he saw as a process in which new institutions take over the tasks necessary in a society to guarantee its survival as the original monolithic institutions break up. This is a devolution from single, less differentiated institutions to an increasingly differentiated subset of institutions.
Following Parsons, this concept of differentiation has been widely applied. As phrased by José Casanova, this "core and the central thesis of the theory of secularization is the conceptualization of the process of societal modernization as a process of functional differentiation and emancipation of the secular spheres—primarily the state, the economy, and science—from the religious sphere and the concomitant differentiation and specialization of religion within its own newly found religious sphere". Casanova also describes this as the theory of "privatization" of religion, which he partially criticizes. While criticizing certain aspects of the traditional sociological theory of secularization, however, David Martin argues that the concept of social differentiation has been its "most useful element".
At present, secularization as understood in the West is being debated in the sociology of religion. In his works Legitimacy of the Modern Age (1966) and The Genesis of the Copernican World (1975), Hans Blumenberg has rejected the idea of a historical continuity – fundamental to the so-called 'theorem of secularization'; the Modern age in his view represents an independent epoch opposed to Antiquity and the Middle Ages by a rehabilitation of human curiosity in reaction to theological absolutism. "Blumenberg targets Löwith's argument that progress is the secularization of Hebrew and Christian beliefs and argues to the contrary that the modern age, including its belief in progress, grew out of a new secular self-affirmation of culture against the Christian tradition." Wolfhart Pannenberg, a student of Löwith, has continued the debate against Blumenberg.
Charles Taylor in "A Secular Age" challenges what he calls 'the subtraction thesis' – that science leads to religion being subtracted from more and more areas of life.
Proponents of "secularization theory" demonstrate widespread declines in the prevalence of religious belief throughout the West, particularly in Europe. Some scholars (e.g., Rodney Stark, Peter Berger) have argued that levels of religiosity are not declining, while other scholars (e.g., Mark Chaves, N. J. Demerath) have countered by introducing the idea of neo-secularization, which broadens the definition of secularization to include the decline of religious authority and its ability to influence society.
In other words, rather than using the proportion of irreligious apostates as the sole measure of secularity, neo-secularization argues that individuals increasingly look outside of religion for authoritative positions. Neo-secularizationists would argue that religion has diminishing authority on issues such as birth control, and argue that religion's authority is declining and secularization is taking place even if religious affiliation may not be declining in the United States (a debate still taking place).
Finally, some claim that demographic forces offset the process of secularization, and may do so to such an extent that individuals can consistently drift away from religion even as society becomes more religious. This is especially the case in societies like Israel (with the ultra-Orthodox and religious Zionists) where committed religious groups have several times the birth rate of seculars. The religious fertility effect operates to a greater or lesser extent in all countries, and is amplified in the West by religious immigration. For instance, even as native whites became more secular, London, England, has become more religious in the past 25 years as religious immigrants and their descendants have increased their share of the population. Across the board, the question of secularization has generated considerable (and occasionally heated) debates in the social sciences.
1870–1930. Christian Smith examined the secularization of American public life between 1870 and 1930. He noted that in 1870 a Protestant establishment thoroughly dominated American culture and its public institutions. By the turn of the 20th century, however, positivism had displaced the Baconian method (which had hitherto bolstered natural theology) and higher education had been thoroughly secularized. In the 1910s "legal realism" gained prominence, de-emphasizing the religious basis for law. That same decade publishing houses emerged that were independent of the Protestant establishment. During the 1920s secularization extended into popular culture and mass public education ceased to be under Protestant cultural influence. Although the general public was still highly religious during this time period, by 1930 the old Protestant establishment was in "shambles".
Key to understanding the secularization, Smith argues, was the rise of an elite intellectual class skeptical of religious orthodoxies and influenced by the European Enlightenment tradition. They consciously sought to displace a Protestant establishment they saw as standing in their way.
2000–2021. Annual Gallup polls from 2008 through 2015 showed that the fraction of American who did not identify with any particular religion steadily rose from 14.6% in 2008 to 19.6% in 2015. At the same time, the fraction of Americans identifying as Christians sank from 80.1% to 69% in 2021. In December 2021 ~21% of Americans declared no religious identity or preference. Given that non-Christian religions stayed roughly the same (at about 5-7% from 2008 to 2021) secularization thus seems to have affected primarily Christians.
In Britain, secularization came much later than in most of Western Europe. It began in the 1960s as part of a much larger social and cultural revolution. Until then the postwar years had seen a revival of religiosity in Britain. Sociologists and historians have engaged in vigorous debates over when it started, how fast it happened, and what caused it.
Sponsorship by royalty, aristocracy, and influential local gentry provided an important support system for organized religion. The sponsorship faded away in the 20th century, as the local élites were no longer so powerful or so financially able to subsidize their favorite activities. In coal-mining districts, local collieries typically funded local chapels, but that ended[when?] as the industry grew distressed and the unionized miners rejected élite interference in their local affairs. This allowed secularizing forces to gain strength.
Data from the annual British Social Attitudes survey and the biennial European Social Survey suggest that the proportion of Britons who identify as Christian fell from 55% (in 1983) to 43% (in 2015). While members of non-Christian religions – principally Muslims and Hindus – quadrupled, the non-religious ("nones") now make up 53% of the British population. More than six in 10 “nones” were brought up as Christians, mainly Anglican or Catholic. Only 2% of “nones” were raised in religions other than Christian.
People who were brought up to practice a religion, but who now identify as having no religion, so-called "non-verts", had different "non-version" rates, namely 14% for Jews, 10% for Muslims and Sikhs, and 6% for Hindus. The proportions of the non-religious who convert to a faith are small: 3% now identify as Anglicans, less than 0.5% convert to Catholicism, 2% join other Christian denominations, and 2% convert to non-Christian faiths.
Spain used to be one of the most religious countries in Europe, but secularization has progressed fast during the past few decades. This was partly due to the anti-clericalism that was one of the roots of the Spanish civil war. Notably, the dictatorship of Francisco Franco embraced “national Catholicism”. However, agreements linked to the constitution of 1978 separated church and state. In 2001, 82% of Spaniards identiﬁed as Catholic but only half did in 2021. Only around 20% of Spaniards go to mass regularly and only 20% of weddings are taking place in a church (2019). Similarly, divorce was legalized in 1981, as was abortion and gay marriage soon after.
Like other European countries, Germany has recorded a decrease in religiosity (in terms of proportion of individuals affiliated to a Church and baptisms for example) but the trends in East and West Germany are significantly different. In East Germany, the process of secularization has been significantly quicker. These differences are explained by sociologists (Jörg Stolz, Detlef Pollack & Nan Dirk de Graaf) by the State repression in the 1950s and 1960s, which challenges predictions of natural cohort replacements stated by the Voas model.

India, post-independence, has seen the emergence of an assertive secular state.
One traditional view of Chinese culture sees the teachings of Confucianism - influential over many centuries - as basically secular.
Chang Pao-min summarises perceived historical consequences of very early secularization in China:
The early secularization of Chinese society, which must be recognized as a sign of modernity [...] has ironically left China for centuries without a powerful and stable source of morality and law. All this simply means that the pursuit of wealth or power or simply the competition for survival can be and often has been ruthless without any sense of restraint. [...] Along with the early secularization of Chinese society which was equally early, the concomitant demise of feudalism and hereditary aristocracy, another remarkable development, transformed China earlier than any other country into a unitary system politically, with one single power centre. It also rendered Chinese society much more egalitarian than Western Europe and Japan.
In this arguably secular setting, the Chinese Communist Party régime of the People's Republic of China (in power on the Chinese mainland from 1949) promoted deliberate secularization.
Main article: Islam and secularism
Many countries in the Arab world show signs of increasing secularization. For instance, in Egypt, support for imposing sharia (Islamic law) fell from 84% in 2011 to 34% in 2016. Egyptians also pray less: among older Egyptians (55+) 90% prayed daily in 2011. Among the younger generation (age 18–24) that fraction was only 70%. By contrast, in 2016 these numbers had fallen to <80% (55+) and <40% (18–24). The other age groups were in between these values. In Lebanon and Morocco, the number of people listening to daily recitals of the Quran fell by half from 2011 to 2016. Some of these developments seem to be driven by need, e.g. by stagnating incomes which force women to contribute to household income and therefore to work. High living costs delay marriage and, as a consequence, seem to encourage pre-marital sex. However, in other countries, such as Jordan and Palestine, support for sharia and Islamist ideas seems to grow. Even in countries in which secularization is growing, there are backlashes. For instance, the president of Egypt, Abdel-Fattah al-Sisi, has banned hundreds of newspapers and websites who may provoke opposition.
There can be no doubt that Confucianism has been a powerful cultural influence throughout East Asia, providing social and political values not only in China, but in Japan, South Korea and Vietnam. [...] [T]here has been the view of Confucianism as nothing but a secular, perhaps even a secularizing morality.
[...] forced secularization is not so easily achieved, and [...] the lengths to which the Soviet and PRC regimes went was insufficient to completely - or even thoroughly - expunge religion from society. [...] [T]hese regimes were willing to go to great lengths to eliminate religion in the name of science and progress, and the outcome at every stage was uncertain.
