Tandoori Chicken is a dish of Mughlai cuisine. It was popular among the noble families and Nawab families. This dish became popular with the ordinary Muslims of South Asia as the Mughal Empire declined.
The tandoori chicken at Moti Mahal so impressed the first Prime Minister of India, Jawaharlal Nehru, that he made it a regular at official banquets. Visiting dignitaries who enjoyed tandoori chicken included American Presidents Richard Nixon and John F. Kennedy, Soviet leaders Nikolai Bulganin and Nikita Khrushchev, the King of Nepal, and the Shah of Iran.
The fame of tandoori chicken led to many derivatives, such as chicken tikka (and eventually the Indian dish popularized in Britain, chicken tikka masala), commonly found in menus in Indian restaurants all over the world.
