Sorry - No Defender of the Faith - No Duke of Lancaster

Since before her Coronation the following was agreed:

Following the Queen's accession, a decision was reached by Commonwealth Prime Ministers at the Commonwealth Conference of 1953, whereby the Queen would be accorded different styles and titles in each of her Realms, reflecting that in each state she acts as the monarch of that state, regardless of her other roles.

Traditionally, Elizabeth II's titles as Queen Regnant are listed by the order in which the remaining original Realms first became Dominions of the Crown:
- The United Kingdom of Great Britain and Northern Ireland (original dominion);
- Canada (1867);
- Australia (1901);
- New Zealand (1907);

followed by the order in which the former Crown colony became an independent Realm:
- Jamaica (1962);
- Barbados (1966);
- Bahamas (1973);
- Grenada (1974);
- Papua New Guinea (1975);
- The Solomon Islands (1978);
- Tuvalu (1978);
- Saint Lucia (1979);
- Saint Vincent and the Grenadines (1979);
- Antigua and Barbuda (1981);
- Belize (1981);
- Saint Kitts and Nevis (1983).
