Religion in South Asia

Hinduism is the largest religion in South Asia with about 1.2 billion Hindus, forming just under two-thirds of South Asia's population. South Asia has the largest population of Hindus in the world, with about 99% of all global Hindus being from South Asia. Hinduism is the dominant religion in India and Nepal and is the second-largest religion in Bangladesh, Pakistan, Sri Lanka, and Bhutan.

Indo-Aryan migrations brought the Indo-Aryans to South Asia, where they compiled and composed the Vedic corpus during the Vedic period (ca. 1500-500 BCE) across present-day Northern India, Pakistan and Afghanistan. The subsequent period, between and , was "a turning point between the Vedic religion and Hindu religions", and a formative period for Hinduism, Jainism and Buddhism. The Epic and Early Puranic period, from c. and 500 CE, saw the onset of the Hindu synthesis, followed by the classical "Golden Age" of India (), which coincides with the Gupta Empire.

Following the conquest of Islamic rulers in the Indian subcontinent and spread of Islam in South Asia, an era featuring persecution of Hindus began and continued until the end of Mughal Empire. The Vijayanagara and Maratha Empire significantly protected and revived Hinduism in the Indian subcontinent, while the Jaffna Kingdom and Gorkha dynasty have significantly protected Hinduism in Sri Lanka and Nepal respectively.

Islam is the second-largest religion in South Asia, with more than 640 million Muslims living there, forming about one-third of the region's population. Islam first spread along the coastal regions of the Indian subcontinent and Sri Lanka, almost as soon as it started in the Arabian Peninsula, as the Arab traders brought it to South Asia. South Asia has the largest population of Muslims in the world, with about one-third of all Muslims living here.^[28][29] Islam is the dominant religion in half of the South Asian countries (Pakistan, Maldives, Bangladesh and Afghanistan). It is the second largest religion in India and third largest in Sri Lanka and Nepal.

On the Indian subcontinent, Islam first appeared in the southwestern tip of the peninsula, in today's Kerala state. Arabs traded with Malabar even before the birth of Muhammad. Native legends say that a group of Sahaba, under Malik Ibn Deenar, arrived on the Malabar Coast and preached Islam. According to that legend, the first mosque of India was built by the mandate of the last King of Chera Perumals of Makotai, who accepted Islam and received the name Tajudheen during the lifetime of the Islamic prophet Muhammad (c. 570–632).^[30][31][32] On a similar note, Tamil Muslims on the eastern coast also claim that they converted to Islam in Muhammad's lifetime. According to Qissat Shakarwati Farmad, the Masjids at Kodungallur, Kollam, Madayi, Barkur, Mangalore, Kasaragod, Kannur, Dharmadam, Panthalayini, and Chaliyam, were built during the era of Malik Dinar, and they are among the oldest Masjids in Indian Subcontinent.^{[33][34] [35]} Historicaly, the Barwada Mosque in Ghogha, Gujarat built before 623 CE, Cheraman Juma Mosque (629 CE) in Methala, Kerala and Palaiya Jumma Palli (630 CE) in Kilakarai, Tamil Nadu are three of the first mosques in South Asia.^{[36][37][38][39][34]}

The first incursion occurred through sea by Caliph Umar's governor of Bahrain, Usman ibn Abu al-Aas, who sent his brother Hakam ibn Abu al-Aas to raid and reconnoitre the Makran region^[40] around 636 CE or 643 AD long before any Arab army reached the frontier of India by land. Al-Hakim ibn Jabalah al-Abdi, who attacked Makran in the year 649 AD, was an early partisan of Ali ibn Abu Talib.^[41] During the caliphate of Ali, many Hindu Jats of Sindh had come under the influence of Shi'ism^[42] and some even participated in the Battle of Camel and died fighting for Ali.^[41] According to popular tradition, Islam was brought to Lakshadweep islands, situated just to the west of Malabar Coast, by Ubaidullah in 661 CE. After the Rashidun Caliphate, Muslim dynasties came to power.^[43][44] Since 1947, South Asia has been largely governed by modern states.^[45][46]

Christianity in Asia has its roots in the very inception of Christianity, which originated from the life and teachings of Jesus in 1st-century Roman Judea. Christianity then spread through the missionary work of his apostles, first in the Levant and taking roots in the major cities such as Jerusalem and Antioch. According to tradition, further eastward expansion occurred via the preaching of Thomas the Apostle, who established Christianity in the Parthian Empire (Iran) and India. The very First Ecumenical Council was held in the city of Nicaea in Asia Minor (325). The first nations to adopt Christianity as a state religion were Armenia in 301 and Georgia in 327. By the 4th century, Christianity became the dominant religion in all Asian provinces of the Eastern Roman Empire.

After the First Council of Ephesus in 431 and the Nestorian Schism, the Nestorian Christianity developed. Nestorians began converting Mongols around the 7th century, and Nestorian Christianity was probably introduced into China during the Tang dynasty (618–907). Mongols tended to be tolerant of multiple religions, with several Mongol tribes being primarily Christian, and under the leadership of Genghis Khan's grandson, the great khan Möngke, Christianity was a small religious influence of the Mongol Empire in the 13th century.

The Fourth Ecumenical Council was held in Asian city of Chalcedon (451). Christological controversies and disputes that surrounded the Council and its aftermath gradually resulted in division between pro-Chalcedonian (Eastern Orthodox) and anti-Chalcedonian (Oriental Orthodox) Christianity.^[47]

At the late 12th and 13th centuries, there was some effort to reunite Eastern and Western Christianity. There were also numerous missionary efforts from Europe to Asia, primarily by Franciscan, Dominican, or Jesuit missionaries. In the 16th century, Spain began to convert Filipinos. In the 18th century, Catholicism developed more or less independently in Korea.

At present, Christianity continues to be the majority religion in the Philippines, East Timor, Armenia, Georgia, Cyprus and Russia. It has significant minority populations in South Korea, Taiwan, China, India, Pakistan, Iran, Indonesia, Vietnam, Singapore, Hong Kong, Japan, Malaysia, Kazakhstan, Kyrgyzstan, Israel, Palestine (including the West Bank and the Gaza Strip), Lebanon, Syria, Iraq, Jordan, and several other countries in Asia with a total Christian population of more than 295 million.^[48]

As of 2021, there are nearly 383 million Christians in Asia.^[49]

Sikhism ( ), also known as Sikhi ( ', , from ), is an Indian religion and philosophy in particular for the Sikh ethnoreligious group that originated in the Punjab region of India around the end of the 15th century CE. The Sikh scriptures are written in the Gurumukhi script particular to Sikhs. It is one of the most recently founded major religious groups and among the largest in the world, with about 25–30million adherents (known as Sikhs).

Sikhism developed from the spiritual teachings of Guru Nanak (1469–1539), the faith's first guru, and the nine Sikh gurus who succeeded him. The tenth guru, Gobind Singh (1666–1708), named the Sikh scripture Guru Granth Sahib as his successor, bringing to a close the line of human gurus and establishing the scripture as the 11th and last eternally living guru, a religious spiritual/life guide for Sikhs. Guru Nanak taught that living an "active, creative, and practical life" of "truthfulness, fidelity, self-control and purity" is above metaphysical truth, and that the ideal man "establishes union with God, knows His Will, and carries out that Will". Guru Hargobind, the sixth Sikh Guru (1606–1644), established the concept of mutual co-existence of the miri ('political'/'temporal') and piri ('spiritual') realms.

The Sikh scripture opens with the Mul Mantar or alternatively spelled "Mool Mantar" (), fundamental prayer about Ik Onkar (). The core beliefs of Sikhism, articulated in the Guru Granth Sahib, include faith and meditation in the name of the one creator; divine unity and equality of all humankind; engaging in seva ('selfless service'); striving for justice for the benefit and prosperity of all; and honest conduct and livelihood while living a householder's life. Following this standard, Sikhism rejects claims that any particular religious tradition has a monopoly on Absolute truth. Sikhism emphasizes simran (, meditation and remembrance of the teachings of Gurus), which can be expressed musically through kirtan, or internally through naam japna ('meditation on His name') as a means to feel God's presence. It teaches followers to transform the "Five Thieves" (i.e., lust, rage, greed, attachment, and ego).

The religion developed and evolved in times of religious persecution, gaining converts from both Hinduism and Islam. The Mughal emperors of India tortured and executed two of the Sikh gurus—Guru Arjan (1563–1605) and Guru Tegh Bahadur (1621–1675)—after they refused to convert to Islam. The persecution of Sikhs triggered the founding of the Khalsa by Guru Gobind Singh in 1699 as an order to protect the freedom of conscience and religion, with members expressing the qualities of a Sant-Sipāhī ('saint-soldier'). The Sikh community may be seen to correspond to A.D. Smith's definition of a politicized community, sharing common ancestry myths and historical memories of martyrdom and persecution under successive rulers.

Buddhism is an ancient Indian religion, which arose in and around the ancient Kingdom of Magadha (now in Bihar, India), and is based on the teachings of Gautama Buddha who was deemed a "Buddha" ("Awakened One"), although Buddhist doctrine holds that there were other Buddhas before him. Buddhism spread outside of Magadha starting in the Buddha's lifetime.

During the reign of the Mauryan Emperor Ashoka, the Buddhist community split into two branches: the Mahāsāṃghika and the Sthaviravāda, each of which spread throughout India and split into numerous sub-sects. In modern times, two major branches of Buddhism exist: the Theravada in Sri Lanka and Southeast Asia, and the Mahayana throughout the Himalayas and East Asia. The Buddhist tradition of Vajrayana is sometimes classified as a part of Mahayana Buddhism, but some scholars consider it to be a different branch altogether.

The practice of Buddhism lost influence in India around the 7th century CE, after the collapse of the Gupta Empire. The last large state to support Buddhism—the Pala Empire—fell in the 12th century. By the end of the 12th century, Buddhism had largely disappeared from India with the exception of the Himalayan region and isolated remnants in parts of south India. However, since the 19th century, modern revivals of Buddhism have included the Maha Bodhi Society, the Vipassana movement, and the Dalit Buddhist movement spearheaded by B. R. Ambedkar. There has also been a growth in Tibetan Buddhism with the arrival of Tibetan refugees and the Tibetan government in exile to India, following the Chinese occupation of Tibet in 1950. According to the 2011 Census there are 8.4 million Buddhists in India (0.70% of the total population).

Jainism ( ), also known as Jain Dharma, is an Indian religion. Jainism traces its spiritual ideas and history through the succession of twenty-four tirthankaras (supreme preachers of Dharma), with the first in the current time cycle being Rishabhadeva, whom the tradition holds to have lived millions of years ago, the twenty-third tirthankara Parshvanatha, whom historians date to the 9th century BCE, and the twenty-fourth tirthankara Mahavira, around 600 BCE. Jainism is considered an eternal dharma with the tirthankaras guiding every time cycle of the cosmology. The three main pillars of Jainism are ahiṃsā (non-violence), anekāntavāda (non-absolutism), and aparigraha (asceticism).

Jain monks take five main vows: ahiṃsā (non-violence), satya (truth), asteya (not stealing), brahmacharya (chastity), and aparigraha (non-possessiveness). These principles have affected Jain culture in many ways, such as leading to a predominantly lacto-vegetarian lifestyle. Parasparopagraho jīvānām (the function of souls is to help one another) is the faith's motto, and the Namokar Mantra is its most common and strongest prayer.

Jainism is one of the oldest religions still practiced today. It has two major ancient sub-traditions, Digambaras and Śvētāmbaras, which hold different views on ascetic practices, gender, and the texts considered canonical. Both sub-traditions have mendicants supported by laypersons (śrāvakas and śrāvikas). The Śvētāmbara tradition in turn has three sub-traditions: Mandirvāsī, Deravasi, and Sthānakavasī. The religion has between four and five million followers, known as Jains or Jainas, who reside mostly in India, where they numbered around 4.5 million at the 2011 census. Outside India, some of the largest Jain communities can be found in Canada, Europe, and the United States. Japan is also home to a fast-growing community of converts. Major festivals include Paryushana and Das Lakshana, Ashtanika, Mahavir Janma Kalyanak, Akshaya Tritiya, and Dipawali.

Zoroastrianism, also known as Mazdayasna and Behdin, is an Iranian religion. One of the world's oldest organized faiths, it is based on the teachings of the Avesta and the Iranian prophet Zoroaster. Zoroastrians exalt an uncreated and benevolent deity of wisdom, commonly referred to as "Ahura Mazda" (), as the universe's supreme being; opposed to Ahura Mazda is "Angra Mainyu" (), who is personified as a destructive spirit and the adversary of all things good. Zoroastranism combines a dualistic cosmology of good and evil with an eschatology predicting the ultimate triumph of Ahura Mazda over evil. Opinions vary among scholars as to whether Zoroastrianism is monotheistic, polytheistic, or henotheistic. Some assert that it combines elements of all three.

With possible roots dating back to the 2nd millennium BCE—the Avestan period—the Zoroastrian religion enters recorded history around the middle of the 6th century BCE. For more than a millennium between and 650 CE, it served as the official religion of the ancient Iranian empires, beginning roughly around the time of the Achaemenid Empire and formally coming to an end with the Muslim conquest of Persia. The fall of the Sasanian Empire and the subsequent persecution of Zoroastrians by the early Muslims culminated in the decline of the religion as a whole. During this time, many Zoroastrians fled to the Indian subcontinent, where they were granted refuge by various kings. Recent estimates place the world's current Zoroastrian population at upwards of 110,000–120,000 people, with the majority of this figure residing in India, Iran, and North America; their number has been thought to be declining.

The most important texts of Zoroastrianism are those contained within the Avesta, which includes the Gathas—the central writings that are thought to have been composed by Zoroaster himself, serving as sacred hymns within Zoroastrian liturgy, known as the Yasna. Zoroastrianism and its holy book (The Avesta and its Commentary Known as Zand) are known to have changed over the centuries. The Avesta itself being "composed at different times, providing a series of snapshots of the religion that allow historians to see how it changed over time".Zoroaster's religious philosophy divided the early Iranian gods of Proto-Indo-Iranian paganism into emanations of the natural world, known as ahuras and daevas, the latter of which were not considered to be worthy of worship. Zoroaster proclaimed that Ahura Mazda was the supreme creator; the creative and sustaining force of the universe, and that human beings are given a choice between supporting Ahura Mazda or not, making them ultimately responsible for their fate. Though Ahura Mazda has no equal contesting force, Angra Mainyu, whose negative forces are born from Aka Manah (evil thought), is considered to be every Zoroastrian's main adversarial force, standing against "Spenta Mainyu" (creative spirit/mentality). Angra Mainyu was further developed by Middle Persian literature into Ahriman (), advancing him to be Ahura Mazda's direct adversary.

Additionally, the life force that originates from Ahura Mazda, known as asha (truth, cosmic order), stands in opposition to druj (falsehood, deceit). Ahura Mazda works in gētīg (the visible material realm) and mēnōg (the invisible spiritual and mental realm) through the seven (or six, when excluding Spenta Mainyu) Amesha Spentas.

Afghanistan is an Islamic state, in which most citizens follow Islam. As much as 90% of the population follows Sunni Islam.^[62] According to The World Factbook, Sunni Muslims constitute between 84.7 and 89.7% of the population, and Shia Muslims between 10 and 15%. Other religions are followed by 0.3% of the population.

The United Nations categorizes Bangladesh as a moderate democratic Muslim country. Sunni Islam is the largest and most dominant religion practiced in the country.

In the Constitution of Bangladesh, Islam is referred to twice in the introduction and Part I of the constitution. The document begins with the Islamic phrase Bismillahir Rahmanir Raheem (بِسْمِ اللهِ الرَّحْمٰنِ الرَّحِيْمِ) which in English is translated as "In the name of Allah, the Beneficent, the Merciful" and article (2A) declares that:"Islam is the state religion of the republic" (although it was added later).

Bhutan is a Buddhist country by constitution and Buddhism plays a vital role in the country.

Religion in India is characterised by a diversity of religious beliefs and practices. Throughout India's history, religion has been an important part of the country's culture and the Indian subcontinent is the birthplace of four of the world's major religions, namely, Buddhism, Hinduism, Jainism, and Sikhism, which are collectively known as native Indian religions or Dharmic religions and represent approx. 83% of the total population of India.

Religion in Nepal encompasses a wide diversity of groups and beliefs. Nepal is a secular nation and secularism in Nepal under the Interim constitution (Part 1, Article 4) is defined as "Religious and cultural freedom along with the protection of religion and culture handed down from time immemorial." That is, "The state government is bound for protecting and fostering Hindu religion while maintaining "Religious" and "Cultural" freedom throughout the nation as fundamental rights.

The official religion of Pakistan is Islam, as enshrined by Article 2 of the Constitution, and is practised by approximately 96.47% of the country's population. The remaining 3.53% practice Hinduism, Christianity, Ahmadiyya Islam (considered non-Muslims by the Pakistani constitution), Sikhism and other religions.

Sri Lanka is officially a Buddhist country, while Sri Lankans practice a variety of religions. As of the 2012 census, 70.2% of Sri Lankans were Buddhists, 12.6% were Hindus, 9.7% were Muslims (mainly Sunni), 7.4% were Christians (mostly Catholics). Buddhism is declared as the State religion of Sri Lanka and has been given special privileges in the Sri Lankan constitution such as the government is bound for protection and fostering of Buddhist Dharma throughout the nation. However, the constitution also provides for freedom of religion and right to equality among all its citizens. In 2008 Sri Lanka was the third most religious country in the world according to a Gallup poll, with 99% of Sri Lankans saying religion is an important part of their daily life.

A caste is a fixed social group into which an individual is born within a particular system of social stratification: a caste system. Within such a system, individuals are expected to: marry exclusively within the same caste (endogamy), follow lifestyles often linked to a particular occupation, hold a ritual status observed within a hierarchy, and interact with others based on cultural notions of exclusion, with certain castes considered as either more pure or more polluted than others. Its paradigmatic ethnographic example is the division of India's Hindu society into rigid social groups. Its roots lie in South Asia's ancient history and it still exists. However, the economic significance of the caste system in India has been declining as a result of urbanisation and affirmative action programs. A subject of much scholarship by sociologists and anthropologists, the Hindu caste system is sometimes used as an analogical basis for the study of caste-like social divisions existing outside Hinduism and India. In colonial Spanish America, mixed-race castas were a category within the Hispanic sector, but the social order was otherwise fluid.

The term "caste" is also applied to morphological groupings in eusocial insects such as ants, bees, and termites.

The caste system in India is the paradigmatic ethnographic instance of social classification based on castes. It has its origins in ancient India, and was transformed by various ruling elites in medieval, early-modern, and modern India, especially in the aftermath of the collapse of the Mughal Empire and the establishment of the British Raj.^{[63][64][65][66]} It is today the basis of affirmative action programmes in India as enforced through its constitution.^[67] The caste system consists of two different concepts, varna and jati, which may be regarded as different levels of analysis of this system.

The caste system as it exists today is thought to be the result of developments during the collapse of the Mughal era and the rise of the British colonial government in India.^[63][68][69] The British Raj furthered this development, making rigid caste organisation a central mechanism of administration.^[68] Between 1860 and 1920, the British incorporated the Indian caste system into their system of governance, granting administrative jobs and senior appointments only to Christians and people belonging to certain castes.^[70] Social unrest during the 1920s led to a change in this policy.^[71] Caste was no longer used by the colonial authority to functionally organize civil society. This reflected changes in administrative practices, understandings of expertise, and the rise of new European scholarly institutions.^[72] After the 1920s, the colonial administration began a policy of positive discrimination by reserving a certain percentage of government jobs for the lower castes. In 1948, negative discrimination on the basis of caste was banned by law and further enshrined in the Indian constitution in 1950;^[73] however, the system continues to be practiced in parts of India.^[67] There are 3,000 castes and 25,000 sub-castes in India, each related to a specific occupation.^[74]

Muslim communities in South Asia have a system of social stratification arising from concepts other than "pure" and "impure", which are integral to the caste system in India. It developed as a result of relations among foreign conquerors, local upper-caste Hindus forced to convert to Islam (ashraf, also known as tabqa-i ashrafiyya) and local lower-caste converts (ajlaf), as well as the continuation of the Indian caste system by converts. Non-ashrafs are backward-caste converts. The concept of "pasmanda" includes ajlaf and arzal Muslims; ajlaf status is defined by descent from converts to Islam and by pesha (profession). These terms are not part of the sociological vocabulary in regions such as Kashmir and Uttar Pradesh, and say little about the functioning of Muslim society.

The Biradari system is social stratification in Pakistan and, to an extent, India. The South Asian Muslim caste system includes hierarchical classifications of khandan (dynasty, family, or lineage).

Hindutva (Hindi pronunciation: [hɪnˈdʊtvə] lit. 'Hindu-ness') is a political ideology encompassing the cultural justification of Hindu nationalism and the belief in establishing Hindu hegemony within India.^{[75][76][77][78]} The political ideology was formulated by Vinayak Damodar Savarkar in 1922.^[79][80] It is used by the Rashtriya Swayamsevak Sangh (RSS), the Vishva Hindu Parishad (VHP), the Bharatiya Janata Party (BJP)^[81][82] and other organisations, collectively called the Sangh Parivar.

Inspired by European fascism,^[83][84] the Hindutva movement has been described as a variant of right-wing extremism,^[85] and as "almost fascist in the classical sense", adhering to a concept of homogenised majority and cultural hegemony.^[86][87] Some have also described Hindutva as a separatist ideology.^[88][89] Some analysts dispute the identification of Hindutva with fascism, and suggest Hindutva is an extreme form of conservatism or ethno-nationalism.^[90]

From a historical perspective, Professor Ishtiaq Ahmed of the University of Stockholm and Professor Shamsul Islam of the University of Delhi classified the Muslims of the subcontinent into two categories during the era of the Indian independence movement: Indian nationalist Muslims (individuals who opposed the partition of India) and Indian Muslim nationalists (individuals who desired to create a separate country for Indian Muslims).^[91][92] The All India Azad Muslim Conference represented Indian nationalist Muslims, while the All-India Muslim League represented the Indian Muslim nationalists.^[92] One such popular debate was the Madani–Iqbal debate.

The Khalistan movement is a separatist movement seeking to create a homeland for Sikhs by establishing an ethno‐religious sovereign state called Khalistan (lit. 'land of the Khalsa') in the Punjab region.^[94] The proposed boundaries of Khalistan vary between different groups; some suggest the entirety of the Sikh-majority Indian state of Punjab, while larger claims include Pakistani Punjab and other parts of North India such as Chandigarh, Haryana, and Himachal Pradesh.^[95] Shimla and Lahore have been proposed as the capital of Khalistan.^[96][97]

The call for a separate Sikh state began during the 1930s, when British rule in India was nearing its end.^[98] In 1940, the first explicit call for Khalistan was made in a pamphlet titled "Khalistan".^[99][100] With financial and political support of the Sikh diaspora, the movement flourished in the Indian state of Punjab – which has a Sikh-majority population – continuing through the 1970s and 1980s, and reaching its zenith in the late 1980s. The Sikh separatist leader Jagjit Singh Chohan said that during his talks with Pakistani prime minister that Zulfikar Ali Bhutto affirmed "we'll help you and make it the capital of Khalistan" and claimed Bhutto wanted revenge over Bangladesh.^[101]

The separatist militant insurgency in Punjab started in the early 1980s.^[102][103] Several militant groups were involved in the armed insurgency, including Babbar Khalsa and Khalistan Commando Force, among others.^[104] In 1986, Khalistan Commando Force took responsibility for the assasination of General Arun Vaidya, in retaliation for 1984's Operation Blue Star.^[105][106] By the mid-1990s, theinsurgency petered out, with the last major incident being the assassination of Chief Minister Beant Singh, who was killed in a bomb blast by a member of Babbar Khalsa.^[107] The movement failed to reach its objective for multiple reasons, including heavy police crackdowns on separatists, factional infighting, and disillusionment from the Sikh population.^[102][108]

There is some support within India and the Sikh diaspora, with yearly demonstrations in protest of those killed during Operation Blue Star.^{[109][110][111]} In early 2018, some militant groups were arrested by police in Punjab, India.^[102] Former Chief Minister of Punjab Amarinder Singh claimed that the recent extremism is backed by Pakistan's Inter-Services Intelligence (ISI) and "Khalistani sympathisers" in Canada, Italy, and the UK.^[112] Simranjit Singh Mann, elected in 2022 from Sangrur, is currently the only openly Khalistani MP in the Indian parliament and his party, and Shiromani Akali Dal (Amritsar) is currently the only pro-Khalistan party in the Indian parliament.^[113][114]
