Q. When was United Provinces officially renamed Uttar Pradesh?
Answer: 24 January 1950
Notes: After India’s independence in August 1947, the United Provinces became a province of the new Dominion of India. The political leadership moved to formally change the name of the state. On 24 January 1950, just before India became a republic, the United Provinces was officially renamed “Uttar Pradesh” (meaning “Northern Province”). The change took effect with the new Constitution of India on 26 January 1950, at which point Uttar Pradesh became a constituent state of the Republic of India. At the same time, three former princely states located within its boundaries – Rampur, Benares (Varanasi), and Tehri Garhwal – were fully merged into Uttar Pradesh. Thus, 1950 marks the statehood of Uttar Pradesh in its modern form.
