No, the Indian Constitution does not make ethnic identity a criterion for citizenship. The Constitution of India, which was adopted on 26th January 1950, provides for citizenship based on specific principles and criteria, rather than ethnic identity. The constitution enshrines the principles of equality, secularism, and non-discrimination, ensuring that citizenship is not determined by one's ethnicity.

The Constitution of India provides for citizenship under Articles 5 to 11. According to Article 5, all individuals who were born in India or whose parents were born in India are considered citizens of India. Article 6 deals with individuals who migrated to India from Pakistan during the partition and provides for their citizenship. Articles 7 and 8 deal with the rights and criteria for citizenship of individuals who migrated to India from Bangladesh and other countries. These articles do not mention ethnicity as a criterion for citizenship, but rather focus on the place of birth or parentage.

Furthermore, the Indian Citizenship Act of 1955 provides for the acquisition and termination of citizenship. It lays down various modes through which individuals can acquire Indian citizenship, such as birth, descent, registration, naturalization, and incorporation of territory. Again, the Act does not have any provision that makes ethnic identity a criterion for citizenship.

The principle of equality and non-discrimination is a fundamental aspect of the Indian Constitution. Article 15 of the Constitution prohibits discrimination on the basis of religion, race, caste, sex, or place of birth. This further reinforces the fact that ethnic identity is not a criterion for citizenship in India.

In conclusion, the Indian Constitution does not make ethnic identity a criterion for citizenship. Citizenship in India is determined by specific principles and criteria mentioned in the Constitution and the Citizenship Act of 1955. The Constitution upholds the principles of equality, secularism, and non-discrimination, ensuring that citizenship is not determined by one's ethnicity.
