Which British king was the last Emperor of India?

George VI (Albert Frederick Arthur George; 14 December 1895 – 6 February 1952) was King of the United Kingdom and the Dominions of the British Commonwealth from 11 December 1936 until his death. He was the last Emperor of India and the first Head of the Commonwealth.

The title Emperor/Empress of India was used by the British monarchs during the British Raj in the Indian Subcontinent from 1876 until 1948, after India had attained independence from the United Kingdom, when for a transitional period the British monarch was also king of the independent dominions of India and Pakistan.

The term "Emperor of India" is also used to refer to pre-British Indian emperors. A Persian language title, which translates to Emperor of India in English, was also used in 1857 by the last Mughal emperor Bahadur Shah II until he was captured by the British.
