Queen Elizabeth II and her husband, Prince Philip, visited New Delhi as part of a nine-day state visit to India in November 1983. The visit coincided with the Commonwealth Heads of Government Meeting (CHOGM), which was hosted by then-Indian Prime Minister Indira Gandhi. The royal couple's tour extended beyond Delhi to other parts of India, including Hyderabad, where the Queen visited an agricultural research institute, the Qutb Shahi tombs, and Holy Trinity Church.
