I was interested to read Ireland's first Constitution in connection with threads here on Griffith and on Irish government relations with the Vatican and have never before read it in full.

Just two items of interest at the first glance - the King of England was the head of State (the Constitution was framed by the Anglo Irish Agreement)
and anyone ordinarily resident in 1922 was granted citizenship.
