What is the capital city of India?

New Delhi is the capital city of India, serving as the seat of the government and the location of key government institutions, including the President's residence, the Parliament, and the Supreme Court. It was officially inaugurated as the capital in 1931, chosen for its strategic location and to symbolize India's transition to a modern nation. New Delhi is part of the larger National Capital Territory of Delhi, which encompasses the surrounding areas.

While Mumbai, Kolkata, and Chennai are major cities in India with significant cultural and economic importance, they do not serve as the capital. Mumbai is known as the financial hub of India, Kolkata has historical significance and rich cultural heritage, and Chennai is recognized for its contributions to the arts and the automobile industry. However, the official administrative functions and diplomatic missions are all centered in New Delhi, making it distinctly the capital city.
