External association
External association was a hypothetical relationship between Ireland and the Commonwealth of Nations proposed by Éamon de Valera in 1921–1922, whereby Ireland would be a sovereign state associated with, but not a member of, the Commonwealth; the British monarch would be head of the association, but not head of state of Ireland. De Valera proposed external association as a compromise between isolationist Irish republicanism on the one hand and Dominion status on the other.
