Secularism is a core principle of Indian civilisation, having played a vital role in bringing together people from diverse backgrounds – a defining characteristic of Indian culture. The success of Indian democracy relies heavily on this principle, as it upholds fundamental values such as justice, liberty, equality, and unity. Its role in integrating different segments of society and fostering a sense of national identity warrants recognition. However, some argue that secularism is no longer relevant in India. This research paper explores various aspects of secularism, beginning with its definition, nature, and scope within India. The second section examines the relationship between democracy and secularism, investigating how they interact. Lastly, the paper considers the growing threats to secularism, including the rise of majoritarianism in India.
