Éire

British subjects in Éire could not vote, hold public office, or work in the government service of Éire, whereas Éire citizens in Britain could do all of these.

In the light of modern scholarship it now seems highly likely that the total recruitment figure for both Northern Irish and Éire citizens in the British Armed Forces stood at around 100–120,000 men and women.

Since Éire remained in the Commonwealth during the war—leaving in 1949—it could be argued that volunteers and war workers from Éire belong in this list. Éire was the only Commonwealth country to remain neutral throughout the war.
