Religion in India
Religion in India is characterised by a diversity of religious beliefs and practices. India is a secular state with no state religion. The Indian subcontinent is the birthplace of four of the world's major religions; namely Hinduism, Buddhism, Jainism and Sikhism.

Religious diversity and religious tolerance are both established in the country by the law and custom; the Constitution of India has declared the right to freedom of religion to be a fundamental right.
