The Indian Constitution
How the world's longest written constitution was drafted, its key principles, and the framework it creates for Indian democracy.
Drafting the Constitution
India's Constitution, adopted on 26 January 1950, is the longest written constitution of any country at nearly 150,000 words. It was drafted by a Constituent Assembly chaired by Dr B.R. Ambedkar, a Dalit scholar and lawyer who insisted on strong protections for marginalised communities. The drafters drew on multiple sources: the Government of India Act 1935 (administrative structure), the US Constitution (fundamental rights, judicial review), the Irish Constitution (directive principles), and the Westminster system (parliamentary government).
The Preamble declares India a 'sovereign, socialist, secular, democratic republic' — though 'socialist' and 'secular' were added by the 42nd Amendment in 1976 during Indira Gandhi's Emergency.
