On which date did the Constitution of India come into force, marking the formal birth of the Republic?

1. The Constitution was *adopted* by the Constituent Assembly on 26 November 1949. 2. It was *brought into force* on 26 January 1950, the date now celebrated as Republic Day. 3. India had become independent earlier on 15 August 1947, but at that point it was still governed by the Government of India Act, 1935. 4. So while 26 November 1949 marks the **adoption** of the Constitution, the date on which it became operative is **26 January 1950**. _Source: ICSI CS Executive (Module 1) — Jurisprudence, Interpretation & General Laws, Lesson 2 'Constitution of India', Broad Framework section, p. 26._
