After the nominal Mughal emperor Bahadur Shah Zafar was deposed at the conclusion of the Indian Rebellion of 1857 (10 May 1857 – 1 November 1858), the government of the United Kingdom decided to transfer control of British India and its princely states from the mercantile East India Company (EIC) to the Crown, thus marking the beginning of the British Raj. The EIC was officially dissolved on 1 June 1874, and the British prime minister, Benjamin Disraeli, decided to offer Queen Victoria the title "empress of India" shortly afterwards. Victoria accepted this style on 1 May 1876. The first Delhi Durbar (which served as an imperial coronation) was held in her honour eight months later on 1 January 1877.
