The Constitution of India is the world's longest written national constitution
The Constitution of India is the supreme legal document of India and the longest written national constitution in the world. It contains 395 articles in 22 parts and 12 schedules, with about 145,000 words. The constitution was drawn from a number of sources, including previous legislation such as the Government of India Acts of 1858, 1892, 1919, and 1935, as well as the Indian Independence Act of 1947. The constitution was drafted by the 389-member Constituent Assembly, which was elected by the members of the provincial assemblies. The assembly sat for eleven sessions over a period of 165 days (some sources state 167 days) to frame the constitution, which was adopted on 26 November 1949 and came into effect on 26 January 1950. The original 1950 constitution is preserved in a nitrogen-filled case at the Parliament Library Building in New Delhi.
The constitution declares India a sovereign, socialist, secular, and democratic republic, assuring its citizens justice, equality, and liberty, and promoting fraternity. It lays down the framework for the fundamental political code, structure, procedures, powers, and duties of government institutions and sets out the fundamental rights, directive principles, and duties of citizens. The constitution also includes important articles such as the Right to Information Act, the Muslim Women (Protection of Rights on Marriage) Act, and the Right to Equality, which prohibits discrimination on grounds of religion, race, caste, sex, or place of birth.
The Constitution of India replaced the Government of India Act 1935 as the country's fundamental governing document, marking India's transition from a dominion of the British Crown to a sovereign, democratic republic. The constitution repealed prior acts of the British Parliament, including the Indian Independence Act of 1947, to ensure constitutional autochthony. This meant that India's constitution would be created by a constituent assembly rather than Parliament, reflecting constitutional supremacy rather than parliamentary supremacy.
Since its adoption, The Constitution of India has been amended 103 times, with a total of 126 Amendment Bills introduced in parliament as of 2020. The constitution continues to evolve, with landmark judgments and constitutional crises shaping its interpretation and application. The Supreme Court of India has also played a significant role in upholding the integrity of the constitution, such as in the case of Kesavananda Bharati v. State of Kerala, where the court held that certain features of the Indian constitution are integral and cannot be amended.

The constitution was adopted by the Constituent Assembly of India on 26 November 1949 and became effective on 26 January 1950, replacing the Government of India Act 1935 as the country's fundamental governing document.
The constitution declares India a "sovereign, socialist, secular, and democratic republic". This means that India is a free country with the complete right to govern itself without interference from any external source. The term "sovereign" signifies India's departure from being a dominion in the British Commonwealth, as set up by the Indian Independence Act of 1947, to becoming a free nation when the Constitution of India came into effect on 26 January 1950.
The term "socialist" is not defined in the Constitution, but the Directive Principles of State Policy in Part IV have a socialist character. These principles embody the philosophy that the welfare of the larger society shall precede individual interests. "Secular" implies that India is not a theocratic state and does not have an official religion. Finally, "democratic republic" indicates that India is a country where the supreme power lies in the body of citizens entitled to vote, and the democratic form of government is a system of government by the whole population or all the eligible members of a state, typically through elected representatives.
The constitution assures its citizens justice, equality, and liberty, and endeavours to promote fraternity. It lays down the framework that demarcates the fundamental political code, structure, procedures, powers, and duties of government institutions, and sets out fundamental rights, directive principles, and the duties of citizens.
