Commonwealth of Nations
Until 1948, there was a consensus among the existing half-dozen Commonwealth members that a Commonwealth realms that became a republic would ceased to be members but the situation changed in 1948 when newly-independent India announced its intention to become a republic on 1 January 1950 although it wished to remain in the Commonwealth.
