The correct answer is 42nd Amendment.
Key Points
- The term "Secular" was added to the Preamble by Indira Gandhi Government in the 42nd amendment.
- Secular means the relationship between the government and the religious groups is defined by constitution and law.
- Under the 42nd Amendment Act, three words were added: Socialist, Secular, and Integrity.
- The Indian Constitution embodies the positive concept of secularism, all the religions in our country have the same status and support from the state.
- However, as the Supreme Court said in 1974, although the words ‘secular state’ was not explicitly mentioned in the Constitution, there can be no doubt that Constitution-makers wanted to establish such a state, and accordingly, Articles 25 to 28 (guaranteeing the fundamental right to freedom of religion) have been included in the constitution.
- On 18 December 1976, during the Emergency in India, the Indira Gandhi government pushed through several changes in the Forty-second Amendment of the constitution.
- Through this amendment, the words "socialist" and "secular" were added between the words "sovereign" and "democratic" and the words "unity of the Nation" were changed to "unity and integrity of the Nation".
