The Preamble to the Constitution of India declares that India is a secular country. The term secularism refers to the governmental practice of indifference towards religion. Secular politics attempt to prevent religious philosophies or bodies from influencing governmental policies. The philosophy that the Indian constitution upholds is a kind of secular humanism made relevant through a historical development of the ideology within the context of religious pluralism in India.

The Constitution of India prohibits discrimination against members of a particular religion, race, caste, sex or place of birth. However, there are many groups in India who claim that secularism isn't trully practiced in India by those who claim they are and claim there is actually pseudo-secularism in India.

The word secular was inserted into the preamble by the Forty-second Amendment.(1976) It implies equality of all religions and religious tolerance. India, therefore does not have an official state religion. Every person has the right to preach, practice and propagate any religion they choose. The government must not favour or discriminate against any religion. It must treat all religions with equal respect. All citizens, irrespective of their religious beliefs are equal in the eyes of law. No religious instruction is imparted in government or government-aided schools. Nevertheless, general information about all established world religions is imparted as part of the course in Sociology, without giving any importance to any one religion or the others. The content presents the basic/fundamental information with regards to the fundamental beliefs, social values and main practices and festivals of each established world religions. The Supreme Court in S.R Bommai v. Union of India held that secularism was an integral part of the basic structure of the constitution.

The Constitution of India (Hindi: भारतीय संविधान; see also names in the other official languages) is the supreme law of India. It lays down the framework defining fundamental political principles, establishes the structure, procedures, powers, and duties of government institutions, and sets out fundamental rights, directive principles, and the duties of citizens. It is the longest written constitution of any sovereign country in the world, containing 444 articles in 24 parts, 12 schedules and 97 amendments. Besides the English version, there is an official Hindi translation. Bodhisattva Dr. Babasaheb Ambedkar[bhimrao ramji Ambedkar] is Chief Architect of Indian Constitution.

The Constitution was enacted by the Constituent Assembly on 26 November 1949, and came into effect on 26 January 1950. The date 26 January was chosen to commemorate the Purna Swaraj declaration of independence of 1930. With its adoption, the Union of India officially became the modern and contemporary Republic of India and it replaced the Government of India Act 1935 as the country's fundamental governing document. The Constitution declares India to be a sovereign, socialist, secular, democratic republic, assuring its citizens of justice, equality, and liberty, and endeavours to promote fraternity among them. The words "socialist" and "secular" were added to the definition in 1976 by constitutional amendment. India celebrates the adoption of the constitution on 26 January each year as Republic Day.
