The Star of India refers to a group of flags used during the period of the British Raj in the Indian subcontinent. India had a range of flags for different purposes during its existence. The Princely states had their own flags which were to be flown alongside the British flag as a symbol of suzerainty. The official state flag for use on land was the Union Flag of the United Kingdom and it was this flag that was lowered on Independence Day in 1947. The flag of the governor-general of India was defaced with the Star of India. The civil ensign and naval ensign were the Red Ensign or Blue Ensign, respectively, defaced with the Star of India emblem.

Emperor or Empress of India was a title used by British monarchs from 1 May 1876 to 22 June 1948 to signify their sovereignty over the Indian Empire as its imperial head of state. The image of the emperor or empress appeared on Indian currency, in government buildings, railway stations, courts, on statues etc. Oaths of allegiance were made to the emperor or empress and the lawful successors by the governors-general, princes, governors, commissioners in India in events such as imperial durbars.
