Page "Fidei defensor" Paragraph 7

At various times, some countries of the Commonwealth retained the title until they formally became republics, e. g. South Africa from 29 May 1953 and Ireland.

Others dropped it even sooner, e. g. in 1953, while still a dominion of the Commonwealth ( till 1956 ), Pakistan dropped the title in recognition of the contradiction between its overwhelmingly Muslim population and having a monarch as the defender of the Christian faith.
