The king 's title , proclaimed under the Royal Titles Act 1901 , was : " George V , by the Grace of God , of the United Kingdom of Great Britain and Ireland and of the British Dominions beyond the Seas King , Defender of the Faith , Emperor of India " At the 1926 Imperial Conference , it was agreed by the government at Westminster and those of the various Dominions that the existing royal style and titles of their shared monarch " hardly accorded with the altered state of affairs arising from the establishment of the Irish Free State as a Dominion " . The Conference concluded that the wording should be changed to : " George V , by the Grace of God , of Great Britain , Ireland and the British Dominions beyond the Seas King , Defender of the Faith , Emperor of India " Under the existing constitutional arrangements of the British Commonwealth , it was necessary for legislation to be enacted by the Parliament of the United Kingdom in order for the royal style and titles to be altered ; the resulting Act would then extend automatically into the law of the various Dominions . The British Government introduced the necessary bill into the House of Commons in March 1927 and easily secured its passage through both Houses of Parliament
