Constituent Assembly of India in the context of "Imperial Legislative Council of India"

Before it gained independence in 1947, India (also called the Indian Empire) was divided into two sets of territories, one under direct British rule (British India), and the other consisting of princely states under the suzerainty of the British Crown, with control over their internal affairs remaining to varying degrees in the hands of their hereditary rulers. The latter included 562 princely states which had different types of revenue-sharing arrangements with the British, often depending on their size, population and local conditions. In addition, there were several colonial enclaves controlled by France and Portugal. After independence, the political integration of these territories into an Indian Union was a declared objective of the Indian National Congress, and the Government of India pursued this over the next decade.

In 1920, Congress (party) under the leadership of Mahatma Gandhi declared swaraj (self-rule) for Indians as its goal and asked the princes of India to establish responsible government. Jawaharlal Nehru played a major role in pushing Congress to confront the princely states and declared in 1929 that "only people who have the right to determine the future of the States must be the people of these States". In 1937, the Congress won in most parts of British India (not including the princely states) in the provincial elections, and started to intervene in the affairs of the states. In the same year, Gandhi played a major role in proposing a federation involving a union between British India and the princely states, with an Indian central government. In 1946, Jawaharlal Nehru observed that no princely state could prevail militarily against the army of independent India. In January 1947, Nehru said that independent India would not accept the divine right of kings. In May 1947, he declared that any princely state which refused to join the Constituent Assembly would be treated as an enemy state. Vallabhbhai Patel, Louis Mountbatten and V. P. Menon were more conciliatory towards the princes, and as the men charged with integrating the states, were successful in the task. Having secured their accession, they then proceeded, in a step-by-step process, to secure and extend the union government's authority over these states and transform their administrations until, by 1956, there was little difference between the territories that had been part of British India and those that had been princely states. Simultaneously, the Government of India, through a combination of military and diplomatic means, acquired de facto and de jure control over the remaining colonial enclaves, which too were integrated into India.

The Constitution of India is the supreme legal document of India, and the longest written national constitution in the world. The document lays down the framework that demarcates fundamental political code, structure, procedures, powers, and duties of government institutions and sets out fundamental rights, directive principles, and the duties of citizens.

It espouses constitutional supremacy (not parliamentary supremacy found in the United Kingdom, since it was created by a constituent assembly rather than Parliament) and was adopted with a declaration in its preamble. The Indian Constitution does not contain a provision to limit the powers of the parliament to amend the constitution. However, the Supreme Court in Kesavananda Bharati v. State of Kerala held that there were certain features of the Constitution so integral to its functioning and existence that they could never be cut out of the constitution (known as the 'Basic Structure' Doctrine).

Bhimrao Ramji Ambedkar (Bhīmrāo Rāmjī Āmbēḍkar; 14 April 1891 – 6 December 1956) was an Indian jurist, economist, social reformer and political leader who chaired the committee that drafted the Constitution of India based on the debates of the Constituent Assembly of India and the first draft of Sir Benegal Narsing Rau. Ambedkar served as Law and Justice minister in the first cabinet of Jawaharlal Nehru. He later renounced Hinduism, converted to Buddhism and inspired the Dalit Buddhist movement.

After graduating from Elphinstone College, University of Bombay, Ambedkar studied economics at Columbia University and the London School of Economics, receiving doctorates in 1927 and 1923, respectively, and was among a handful of Indian students to have done so at either institution in the 1920s. During his time at the Columbia University, Ambedkar came under the influence of John Dewey and his philosophy of pragmatism. He also trained in the law at Gray's Inn, London. In his early career, he was an economist, professor, and lawyer. His later life was marked by his political activities; he became involved in campaigning and negotiations for partition, publishing journals, advocating political rights and social freedom for Dalits, and contributing to the establishment of the state of India. In 1956, he converted to Buddhism, initiating mass conversions of Dalits.

"Jana Gana Mana" is the national anthem of the Republic of India. It was originally composed as "Bharoto Bhagyo Bidhata" in Bengali written by polymath, activist and country's first Nobel laureate Rabindranath Tagore on 11 December 1911. The first stanza of the song "Bharoto Bhagyo Bidhata" was adopted by the Constituent Assembly of India as the National Anthem on 24 January 1950. A formal rendition of the national anthem takes approximately 52 seconds. A shortened version consisting of the first and last lines (and taking about 20 seconds to play) is also staged occasionally. It was first publicly sung on 27 December 1911 at the Calcutta (present-day Kolkata) Session of the Indian National Congress.

The Preamble to the Constitution of the Republic of India is based on the Objectives Resolution, which was moved in the Constituent Assembly by Jawaharlal Nehru on 13 December 1946 accepted on 22 January 1947 and adopted by the Constituent Assembly on 26 November 1949, coming into force on 26 January 1950, celebrated as the Republic Day of India, and was initially drafted by Jawaharlal Nehru. The words "socialist", "secular" and "integrity" were later added during the Indian emergency by Indira Gandhi.

The Constitution of India's preamble, as amended up to July 2024, reads as follows:

The Partition of Bengal in 1947, also known as the Second Partition of Bengal, part of the Partition of India, divided the British Indian Bengal Province along the Radcliffe Line between the Dominion of India and the Dominion of Pakistan. The Bengali Hindu-majority West Bengal became a state of India, and the Bengali Muslim-majority East Bengal (now Bangladesh) became a province of Pakistan.

On 20 June 1947, the Bengal Legislative Assembly met to decide the future of the Bengal Province, as between being a United Bengal within India or Pakistan or divided into West Bengal and East Bengal as the homelands for the Bengali Hindus and the Bengali Muslims, respectively. At the preliminary joint session, the assembly decided by 126–90 that if it remained united, it should join the new Constituent Assembly of Pakistan. Later, a separate meeting of legislators from West Bengal decided by 58–21 that the province should be partitioned and that West Bengal should join the existing Constituent Assembly of India. In another separate meeting of legislators from East Bengal, it was decided by 106–35 that the province should not be partitioned and by 107–34 that East Bengal should join Pakistan in the event of Partition.

The Old Parliament House, officially known as the Samvidhan Sadan (Constitution House), was the seat of the Parliament of India between 26 January 1950 and 18 September 2023. It housed the Lok Sabha and the Rajya Sabha (the lower and upper houses) respectively in India's bicameral parliament for nearly 73 years. Earlier it had served as the seat of the Imperial Legislative Council between 18 January 1927 and 15 August 1947, and the Constituent Assembly of India between 15 August 1947 and 26 January 1950.

The building was designed by British architects Edwin Lutyens and Herbert Baker and was constructed between 1921 and 1927. It was opened in January 1927 as the seat of the Imperial Legislative Council and was known as the Council House. Following the Indian Independence in 1947, it was taken over by the Constituent Assembly of India, and then became the seat of the Indian Parliament on 26 January 1950 with India becoming a republic following the adoption of the Indian Constitution.

The national flag of India, colloquially called Tiraṅgā (the tricolour), is a horizontal rectangular tricolour flag, the colours being of India saffron, white and India green; with the Ashoka Chakra, a 24-spoke wheel, in navy blue at its centre. It was adopted in its present form during a meeting of the Constituent Assembly held on 22 July 1947, and it became the official flag of the Union of India on 15 August 1947. The flag was subsequently retained as that of the Republic of India. In India, the term "tricolour" almost always refers to the Indian national flag.

The flag is based on the Swaraj flag, a flag of the Indian National Congress adopted by Mahatma Gandhi after making significant modifications to the design proposed by Pingali Venkayya. This flag included the charkha which was replaced with the chakra in 1947 by Jawaharlal Nehru.

Republic Day is a national holiday in India commemorating the adoption of the Constitution of the Republic of India and the country's transition to a republic which came into effect on 26 January 1950.

The constitution replaced the Government of India Act 1935 as the governing document of India, thus turning the nation from a dominion into a republic, following its independence from the British Raj in 1947. The constitution was adopted by the Constituent Assembly of India on 26 November 1949 and came into effect on 26 January 1950. The date was chosen because the Indian National Congress had proclaimed Purna Swaraj (complete independence) on that date in 1930.
