Hinduism
~80% of India's population
Hinduism is the oldest religion in the world and India's dominant faith, practised by approximately 80% of the population. Also known as Sanatan Dharma (the Eternal Way), it is the world's third-largest religion after Christianity and Islam. Hinduism is not a single religion but a family of diverse traditions, philosophies and beliefs united by core concepts — Dharma (duty), Karma (action and consequence), Moksha (liberation), and devotion to deities such as Brahma, Vishnu and Shiva.

Islam
~14% of India's population
Islam is India's largest minority religion and the world's second-largest faith. India has approximately 200 million Muslims — one of the world's largest Muslim populations. Islam's contact with India began early, with real push in the 8th century. Indian Islam has developed a unique syncretic character through centuries of coexistence with Hindu, Buddhist, and Jain traditions. The Sufi tradition of Islam is particularly influential in India, and shrines like the Dargah of Hazrat Nizamuddin Auliya in Delhi are visited by people of all faiths.

Christianity
~2.3% of India's population
Christianity is one of the prominent religions in India, with approximately 25 million Christians — more than the entire population of Australia. Christianity came to India as early as the 1st century AD with Saint Thomas the Apostle, who is said to have arrived on the Malabar Coast (Kerala) in 52 AD. Indian Christianity is extremely diverse, encompassing Syrian Christians, Roman Catholics, Protestants, and evangelical traditions. Goa, Kerala, and Nagaland have particularly strong Christian traditions.

Sikhism
~1.7% of India's population
Sikhism was founded in the Punjab by Guru Nanak Dev Ji (1469–1539) and developed through 10 Gurus. The word 'Sikh' means a disciple, and Sikhism is essentially the path of discipleship. Sikhs form about 2% of India's population but are among the most visible and influential communities. The Golden Temple (Harmandir Sahib) in Amritsar is the holiest shrine of Sikhism and one of India's most visited destinations. The Sikh community is known for seva (selfless service), including running the world's largest free communal kitchens (langar).

Buddhism
~0.7% of India's population
Buddhism originated in India with the teachings of Siddhartha Gautama (563–483 BC), a royal prince of Kapilvastu. After attaining enlightenment under the Bodhi tree at Bodh Gaya (Bihar), he became the Buddha. Buddhism spread across Central Asia, Sri Lanka, Tibet, Southeast Asia, China, Korea, Japan, and beyond. While Buddhism has fewer followers in India today (~0.7%), India is home to some of the most sacred Buddhist sites: Bodh Gaya, Sarnath, Kushinagar, and Lumbini (near the Nepal border).

Jainism
<1% — powerful community influence
Jainism is traced to Vardhamana Mahavira (The Great Hero, 599–527 BC), though Jainism existed even before him. For centuries, Jains have been famous as a community of traders and merchants. Jains form less than 1% of India's population but have enormous economic influence — they control a significant portion of India's diamond trade, banking, and textile industries. The states of Gujarat and Rajasthan have the highest concentration of Jain population. The principle of Ahimsa (non-violence) from Jainism profoundly influenced Mahatma Gandhi.

Zoroastrianism (Parsi)
~70,000 in India — tiny but influential
Though Zoroastrians (Parsis) number only around 70,000 in India, they remain one of the most influential religious communities. Most Parsis live in Maharashtra (mainly Mumbai) and Gujarat. The Zoroastrian community has produced some of India's greatest industrialists including the Tata family, scientists, musicians, and leaders. Their contributions to Indian industry, charity, and culture far exceed their small numbers. The sacred fire in Zoroastrian temples (Atash Behram) is kept perpetually burning.

Judaism & Bahá'í Faith
Small but significant communities
India has one of the world's oldest Jewish communities — the Bene Israel community of Maharashtra and the Cochin Jews of Kerala, who have lived in India for over 2,000 years. India is historically renowned for never having persecuted its Jewish population. The Bahá'í Faith, which emphasises the unity of all religions and humanity, has its most visited pilgrimage site in India — the magnificent Lotus Temple in New Delhi, which attracts over 4 million visitors annually.
