The Republic Day of India marks the anniversary of the adoption of the Constitution of India and the transition of India from a British Dominion to a republic on January 26, 1950.

Although India obtained its independence on August 15, 1947, it did not yet have a permanent constitution; instead, its laws were based on the modified colonial Government of India Act 1935, and the country was a Dominion, with George VI as head of state and Earl Mountbatten as Governor General. On August 29, 1947, the Drafting Committee was appointed to draft a permanent constitution, with Bhimrao Ramji Ambedkar as chairman.
