The transition of India from a British colony to an independent nation on August 15, 1947, was legally anchored in the Indian Independence Act, 1947. Enacted by the British Parliament on July 18, 1947, this statute was based on the Mountbatten Plan of June 3, 1947. It brought an end to the British Raj by creating two independent Dominions: India and Pakistan.
Key Structural Provisions of the 1947 Act
- Lapse of Paramountcy: British suzerainty over the 562 Princely States terminated on August 15, 1947, returning them to their technically independent status before they signed Instruments of Accession.
- Sovereignty of the Constituent Assembly: The Constituent Assembly of India, formed in 1946 under the Cabinet Mission Plan, was elevated to a fully sovereign legislative body. It assumed the dual authority of drafting the Constitution and enacting ordinary central laws.
- Adaptation of the 1935 Act: Until the new Constitution was formally adopted on January 26, 1950, the Dominion of India was administered under the modified framework of the Government of India Act, 1935.
- Omission of the Imperial Title: The title “Emperor of India” was officially dropped from the British Royal Style and Titles by a royal proclamation.
Chronology of the Transfer of Power
The final phase of the freedom struggle moved rapidly from the arrival of the last Viceroy to the declaration of independence.

The Midnight Session and the Birth of Independent India
Setting the Date: Why August 15?
Lord Mountbatten selected August 15, 1947, as the date for the transfer of power because it marked the second anniversary of the unconditional surrender of Japan to the Allied Forces in World War II, a victory Mountbatten had personally overseen as the Supreme Allied Commander in Southeast Asia. Due to astrological concerns raised by Indian scholars regarding the suitability of August 15, a compromise was reached to hold the sovereign session on the midnight turning from August 14 to August 15, which satisfied both administrative and traditional calendars.
Proceedings of the Historic Session
- Presidential Chairmanship: The historic midnight session of the Constituent Assembly was presided over by Dr. Rajendra Prasad at the Constitution Hall (now the Central Hall of Parliament) in New Delhi.
- National Song: The session commenced at 11:00 PM on August 14 with the singing of Vande Mataram by Sucheta Kripalani.
- The Tryst with Destiny: Minutes before midnight, Jawaharlal Nehru delivered his historic address, emphasizing the end of an era and the soul of a nation long suppressed finding utterance.

- Presentation of the Tricolor: A group of Indian women, represented by Hansa Mehta, formally presented the National Flag of independent India to the Assembly on behalf of the women of India.
Administrative and Political Governance on Day One
The Transition of Executive Heads
Upon independence, the office of the Viceroy was abolished. India became an independent Dominion within the British Commonwealth, retaining a constitutional Governor-General as the representative of the Crown until it transitioned to a Republic.
- Governor-General of India: Lord Louis Mountbatten was requested by the Indian leadership to serve as the first Governor-General of independent India, a post he held until June 1948.
- Prime Minister: Jawaharlal Nehru was sworn in as the first Prime Minister of independent India by Governor-General Mountbatten on the morning of August 15, 1947.

The first cabinet was structured as a national coalition government, incorporating prominent non-Congress leaders and domain experts to ensure stability during partition.
- Jawaharlal Nehru: Prime Minister; External Affairs and Commonwealth Relations; Scientific Research.
- Sardar Vallabhbhai Patel: Deputy Prime Minister; Home; Information and Broadcasting; States.
- Dr. B.R. Ambedkar: Minister of Law (Nominated by Congress despite being a fierce critic, ensuring his leadership over the Drafting Committee).

Territorial Realities and Geopolitical Dynamics
The Redrawn Borders
The geographic limits of the newly independent state were drawn by the Boundary Commissions led by Sir Cyril Radcliffe. The delay in publishing the Radcliffe Award until August 17 meant that on August 15, 1947, the populations of border districts in Punjab (such as Gurdaspur and Amritsar) and Bengal (such as Nadia and Murshidabad) celebrated independence without knowing which dominion they belonged to.
Status of Non-British Enclaves
On August 15, 1947, significant portions of the Indian subcontinent remained under non-British European colonial rule and were not part of the initial Independence Day celebrations.
- French India: Enclaves including Pondicherry, Karikal, Yanam, Mahé, and Chandernagore remained under French administrative control until their de facto transfer in 1954 and de jure integration in 1962.
- Portuguese India: Goa, Daman, Diu, Dadra, and Nagar Haveli remained under Portuguese rule. Dadra and Nagar Haveli were liberated in 1954, while Goa, Daman, and Diu were integrated into the Indian Union through military intervention via Operation Vijay in December 1961.
Symbols and Protocols Established on Independence Day
Evolution of the National Flag
The National Flag hoisted on Independence Day was adopted by the Constituent Assembly on July 22, 1947. It was an adaptation of the Swaraj Flag designed by Pingali Venkayya. The spinning wheel (Charkha) at the center was replaced by the 24-spoke Dharma Chakra (Wheel of Law) from the Ashoka Lion Capital at Sarnath to ensure visual symmetry and historical continuity.
The Anthem and the State Emblem
- National Anthem: While Jana Gana Mana (composed by Rabindranath Tagore in 1911) and Vande Mataram (written by Bankim Chandra Chattopadhyay) were sung during the independence proceedings, Jana Gana Mana was officially declared the National Anthem, and Vande Mataram the National Song, on January 24, 1950.
- Hoisting Protocol: By established constitutional protocol, the Prime Minister of India hoists the National Flag at the fortifications of the Red Fort in Delhi on Independence Day, delivering an address to the nation. This contrasts with Republic Day (January 26), where the President of India unfurls the flag at Kartavya Path as the constitutional Head of State.
Historical Trivia and Prelims-Specific Facts
Mahatma Gandhi’s Absence from New Delhi
Mahatma Gandhi did not participate in any official Independence Day celebrations or the midnight session of the Constituent Assembly. On August 15, 1947, he was stationed at Beliaghata in Calcutta (now Kolkata), fasting and holding prayers to quell the violent communal riots ravaging Bengal.
The First Flag Hoisting Site
The first public hoisting of the National Flag by Prime Minister Jawaharlal Nehru did not take place at the Red Fort on August 15. On the morning of August 15, Nehru took the oath at the Government House (now Rashtrapati Bhavan). The public flag hoisting ceremony occurred later that afternoon at the Princes Park near India Gate. The symbolic flag hoisting at the Red Fort took place the following morning, on August 16, 1947.
The Last British Troops to Leave
The transfer of power did not mean the immediate evacuation of all British military personnel. The first contingent of British troops left Indian shores on August 17, 1947. The final unit, the 1st Battalion of the Somerset Light Infantry, departed from Bombay through the Gateway of India on February 28, 1948, formally drawing the curtain on the British military presence in India.
