Secularism is the principle of separation between government institutions and the persons mandated to represent the State from religious institutions and religious dignitaries. In one sense, secularism may assert the right to be free from religious rule and teachings, and the right to freedom from governmental imposition of religion upon the people within a state that is neutral on matters of belief. (See also separation of church and state and Laïcité.) In another sense, it refers to the view that human activities and decisions, especially political ones, should be unbiased by religious influence. (See also public reason.) Some scholars are now arguing that the very idea of secularism will change.

Secularism draws its intellectual roots from Greek and Roman philosophers such as Marcus Aurelius and Epicurus; medieval Muslim polymaths such as Ibn Rushd; Enlightenment thinkers such as Denis Diderot, Voltaire, Baruch Spinoza, John Locke, James Madison, Thomas Jefferson, and Thomas Paine; and more recent freethinkers, agnostics, and atheists such as Robert Ingersoll and Bertrand Russell.

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.
